usmile Y10 Pro Sonic Electric Toothbrush: One minute review
The usmile Y10 Pro Sonic Electric Toothbrush is smart brush that gets you some high-end features, in a model that is priced lower than you might expect. There are few other screen-toting brushes out there, and you'll pay a premium for that. So does that help get the Y10 Pro in the list of best electric toothbrush options?
A screen alone won't do that, but when combined with all the other features this is a very compelling option for your mouth indeed. The brush is adaptive meaning it's able to change the power and style of brushing to suit the various parts of your mouth. All that should mean an ideal clean without damaging your gums in the process.
Then there's that stunning battery life. Despite packing in the features, this can keep it going for a whopping six months before it needs a charge. That makes it better than the top-end premium likes of the Oral-B iO Series 10 and the Philips Sonicare DiamondClean 9000.
This even charges using traditional USB-C, meaning no silly bathroom charger you need to carry about with you. That said, it doesn't come with a travel case and some of the guidance on the screen can be oddly worded. But with four cleaning modes, well-designed bristle head and a sleek finish, this is an impressive brush indeed.

usmile Y10 Pro Sonic Electric Toothbrush review: Price and availability
Priced at $109 / £86 / AU$166
The usmile Y10 Pro Sonic Electric Toothbrush is available online to be bought directly from the company and shipped internationally. The price stands at $109 / £86 / AU$166 although this can vary.
At time of publishing, for example, there is a sale on and the pricing is $88.49 / £70 / AU$170. That gets you the brush, two brush heads and a USB-C charging cable.

(Image credit: Future)
IPX8 waterproof
USB-C charging
Color display
This brush certainly looks premium with that sleek finish, color display, and those quality-looking metallic edges to the screen and main button. The shape is pretty standard, largely because that shape works for comfort and weight balance. That said, this is a little longer than some – likely down to that inbuilt USB-C charging port and the very long battery life.
The head is easily replaceable and features a wave design to the bristles for deep cleaning. This is designed specifically to whiten teeth and penetrate deeply. Helpfully, the colors of the head are designed to fade over a period of three months so you can see when it's time to replace that with a new head.
There are two buttons, one to power the brush on and off and another to select modes and cycle through them. The brush is IPX8 waterproof, meaning it's sealed to the wet, to the point that you can brush your teeth while in the shower, if that's your thing.
The brush features a gyroscopic sensor which helps it to recognise the position you're using it in. That means it can offer more intelligent feedback, guidance and adaptiveness to give you the ideal brushing experience.
Design score: 5 / 5
usmile Y10 Pro Sonic Electric Toothbrush review: Features
(Image credit: Future)
Impressive six-month battery
Fast charging
Four modes
One of the most impressive features of the Y10 Pro is a superb six-month battery life. That's based on you brushing twice daily for two minutes a session. So even if this comes up a little short of that, you're still looking at months more battery life than even the best efforts from big names like Oral-B and Philips. Then, with a four-hour charge from a standard USB-C cable, it means you rarely need to think about battery – twice a year, rarely.
That display is another of the powerful weapons in this brush's arsenal. It means that you can see the mode you're using, you can see a timer, you get feedback on details like plaque, you can see the areas in your mouth you need to brush, and you get a stats read-out at the end.
Feedback is an important feature too as the brush is equipped to detect how you're brushing and adapt its sonic vibrations to suit. That can mean pulsations between 31,000 and 38,000 per minute to get you the best brush for your teeth, but while protecting your gums in the process.
There is a lack of a travel case, but since this keeps the price down it can be a good thing – presuming you don't need one. It's a shame there isn't an option to buy one with it, or as an accessory though.
Features score: 4.5 / 5
usmile Y10 Pro Sonic Electric Toothbrush review: Performance
(Image credit: Future)
Decent power levels
Amazing battery life
Odd feedback messages
When it comes to performance, this brush certainly packs plenty of power, giving enough sonic movement to really feel like you're getting the plaque and dirt off your teeth. The screen, which shows the area of your mouth that's been brushed or missed is also impressive, using the gyroscope to detect where you've brushed.
The timer with haptic feedback helps you to move between mouth sectors every 30 seconds. There is a red LED on the back to show when you're using too much force, although you'll need to either be in front of the mirror, or in the dark, to be able to see that flashing as it's oddly placed on the back of the brush.
The battery does indeed just keep going, so that's not something you'll need to worry about. With a display of how much life it has left displayed on that screen, you can keep track and rest easy knowing you have enough juice left – ideal if you're away and don't want to have to charge, for example. Although with that USB-C port even charging can be simple, using a phone cable.
The language on the display is a little odd at times, telling you "need enhance" presumably for better brushing being required. Or saying "many plaques" which makes sense but just feels budget that this wasn't picked up in production, and leaves you wondering about what other areas did get enough attention to detail.
For example, the four modes of Smart, Clean, White and Soft are supposed to adapt the vibrations on the brush head based on the modes and what area of your mouth it detects you working on. In reality, it's pretty tough to feel much difference which leaves you wondering just how effective these advanced claims are. That said, it does feel clean after use so even if every detail isn't as good as it seems, the results speak for themselves.
Performance score: 4/5

How I tested
I used the usmile Y10 Pro Sonic Electric Toothbrush for weeks in order to test the effectiveness of the brush itself as well as that battery performance. I also visited the dentist during this time and was complemented on my cleaning efforts - reflecting well on this brush's performance.
My brushing was twice daily with that two-minute timer and haptic half-minute guidance vibrations used to get a full and fair brush.
I was also testing other brushes from Oral-B and more which allowed me to see the difference between features like extra modes, oscillations versus sonics, battery life, screes, apps and more.
The Zoma Hybrid mattress is a 12-inch (30cm) tall hybrid mattress with memory foam and pocket springs, and is available in both the US and the UK. The brand is geared specifically towards using sleep for recovery, and promises 'cutting-edge sleep technology'. For this review, I slept on a UK king-size for four weeks, alongside my husband. I also ran several objective tests for performance aspects like pressure relief and edge support. The aim was to cut through the tech-talk and see how this model really matches up against the rest of today's best mattresses.
The overall feel is firmly springy. There is memory foam here, but it's paired with a bouncier foam layer and the overall feel is responsive, with minimal contouring. There's no indication of firmness on the Zoma website but I'd say it's around an 8.5 out of 10 (with 10 being the firmest). Myself and my husband (5ft 8 and 6ft 4 respectively, with a combined weight of 190kg) both found it far too firm for side sleeping, and it caused pressure to build up uncomfortably in our shoulders. It's far more comfortable for back sleeping, where the foams and coils help distribute weight evenly and keep the spine aligned.

Elsewhere, the mattress performed well. The edges are nice and sturdy, so if you, like me, end up pushed to the side of the bed by a toddler in the middle of the night, you shouldn't have to worry about rolling off. I was also impressed by the temperature regulation; I had no issues with overheating during my review period.
In terms of price, this mattress is almost always discounted (in the UK and the US) and generally sits in the mid-range price bracket. That's a good price for a hybrid model, but if it's a competitive bracket and there are cheaper models in our best hybrid mattressguide that offer similar quality.
At time of writing, Zoma isn't a particularly well-known brand in the UK, but it has a following in the States with some high praises from athletes. I was impressed by some of the brand's sustainability practices in the UK – it offers free old mattress recycling and it has a 'zero waste to landfill' policy in its factories. For more details on these points, read on for my full Zoma Hybrid mattress review.
Zoma Hybrid mattress review: price & value for money
Never sold at full price; consistent discounts in both US and UK
Sits in the mid range, and well priced for a hybrid
... although there is strong competition in this bracket
At ticket price, the Zoma Hybrid is getting into the premium mattress space. It is, however, very rarely sold at full price. In the US, expect $150 off all sizes, and in the UK there's usually £250 off. Based on the typical prices you'll actually pay, it sits in the mid-range price bracket in both the US and the UK.
Here's the pricing for the Zoma, alongside the discounted price you can expect to actually pay.
In the US:
Twin: MSRP $749 (usually sold at $599)
Full: MSRP $949 (usually sold at $799)
Queen: MSRP $1,149 (usually sold at $999)
King: MSRP $1,349 (usually sold at $1,199)
California King: MSRP $1,349 (usually sold at $1,199)
In the UK:
Single: £749 (usually sold at £499)
Double: £849 (usually sold at £599)
King: £949 (usually sold at £699)
Super king: £1,149 (usually sold at £899)
Overall, the mattress feels well made, and that's a decent price for a hybrid (most of today's best cheap mattresses tend to be all-foam models.). I have tested mattresses that suit my sleep style better and that I think are better value for money (read more in the alternatives section) but it's competitively priced in the wider market.
Hybrid mattress with several types of foam and pocket coils
Breathable mesh fabric cover, not removable and no handles
12" (30cm) tall, on all sizes, although review model was a bit shorter
The Zoma Hybrid is a hybrid of different foams and pocketed springs, and it's made in the US or UK (depending where you reside). The top layer is a memory foam that has been designed to provide targeted support and relieve pressure on joints. It's infused with gel to promote cooling. A layer down is something Zoma calls 'Reactiv'. It's designed to be responsive and bounce back quickly.
(Image credit: Zoma)
Underneath these two types of foam is where you'll find the hundreds (no specifics given) of 19cm pocketed coils. These are there to add stability and support, and will also allow air to move through the mattress, aiding with breathability. It looks like there may be a layer of base foam beneath the coils (there's reference to a 'high-density base layer' but again, no specifics are given). If you're not bothered by having coils, there's an all-foam version of this mattress available too.
There's a zip, but Zoma says the cover shouldn't be removed (Image credit: Future)
The Zoma Hybrid is wrapped in a soft, breathable cover that it calls 'AirCloth'. This knitted material is designed to wick away heat and moisture. It's not removable or washable – there is a zip, but that's for manufacturing purposes only – and there's no non-slip gripping anywhere that I can see to help keep the mattress firmly on the bed base. It also doesn't have handles, which could be a problem if you need to move it at any time because it's pretty heavy.
(Image credit: Future)
Officially it's 12 inches (30cm) tall, but I measured by review model in a few spots and it was only 11.2 inches (28.5cm). Regardless, it's still on the thicker side, so you'll probably need some deep-fitted sheets.
Design score: 4 out of 5
Zoma Hybrid mattress review: comfort & support
No firmness indicated on Zoma website, but I rate it 8.5 out of 10 (firm)
Most comfortable in a back sleeper position
Springy, responsive feel, with minimal contouring
I'd describe the Zoma Hybrid as having a 'firm bounce'. There is memory foam here, but it's paired with a bouncier foam layer and the overall feel is responsive. The foams contour slightly around the sleeper, but don't expect a body-hugging feel. The upper foam layers are thick, so you can't feel the coils through them. When the pressure is removed from the surface of the mattress, it returns to shape almost immediately.
To test the firmness I placed my 10kg weight in the middle of the mattress; it sunk by 1.5 inches. Unusually, there's no indication on the Zoma website of how firm this mattress is. I emailed a rep and the rating they gave me was in our 'soft' bracket, but I'd completely disagree with that. Although it did soften up a bit over the course of our testing period, it's definitely a firm mattress – I'd rate it around an 8.5 out of 10 on firmness (with 10 being rock-hard). It's a contender for TechRadar's best firm mattressguide.
(Image credit: Future)
Throughout the testing I found that I was most comfortable laying on my back, even though I am naturally a side sleeper and it took me a while to adapt to this new position. This was the same for my husband. When laying on my back it felt like my weight was more evenly distributed, and helped to realign my spine after hunching over a computer all day.
However, laying on my side quickly became uncomfortable – I woke a couple of times in the night during testing with pins-and-needles on the side I was lying on. My husband experienced a similar thing. For reference, we have a combined weight of 198kg, and are taller than average; I'm 5ft 8 and my husband is 6ft 4.
That's not really a surprise – the best mattresses for side sleeperstend to be a bit softer (between 5 and 7.5 out of 10 on firmness), to allow the shoulder to sink in a bit, and prevent pressure from building up in this area. Even though we typically like quite a solid mattress, my husband and I found it was far too firm for us.
Zoma says there's no real weight limit on the mattress, but the general industry recommendation is 115kg per sleeper. However, I found myself rolling inwards towards my partner, who's the heavier of the two of us, in the night.
Zoma Hybrid mattress review: performance
Great temperature regulation – no issues with overheating
Some motion transfer but only an issue for light sleepers
Excellent edge support
As well as taking into account the comfort and pressure relief of the Zoma Hybrid, for this review I have also focused on: temperature regulation (how hot or cool one feels on the mattress), motion isolation (how well it absorbs movements on the surface) and edge support (how sturdy the edge of the mattress is). Read on for my findings…
Temperature regulation
Memory foam can have a habit of clinging on to body heat, and many brands use fancy terminology to make it sound like you're getting a cooler option. The only way you'll know if it actually works or not is to either try it out, or read a review.
The memory foam in the Zoma Hybrid mattress is infused with gel, with the aim of aiding temperature regulation. Whether it's down to the gel or not, I found the Zoma did a great job of keeping me at a comfortable temperature.
(Image credit: Future)
I was in the middle of a new home renovation during my testing period, so I slept on the Zoma in cold UK winter temperatures either with no heating or with raging heating while waiting for a thermostat. I didn't wake once feeling hot during the night, which is a sign that this aspect of the mattress spec was performing as it should.
Temperature regulation score: 4.5 out of 5
Motion isolation
This is about how movement transfers across the mattress. If a mattress has poor motion isolation, you'll feel it when your bed-sharer turns over or gets into or out of bed. If you're a restless sleeper and/or share a bed, it's worth paying attention to this aspect of performance.
To try out the Zoma Hybrid for motion isolation I bravely put my 10kg weight next to a pint-sized glass with some water in it. The glass (almost) fell over at 3.5-inches, wobbled at 8-inches but was safe at 12-inches away from the weight.
(Image credit: Future)
I also tested out the motion isolation in the real world, by moving around in bed, and asking my husband to move around too. The bouncy feel means there is a bit of motion transfer. I could feel my partner changing position and getting in and out of bed, and vice versa, although there wasn't enough movement for it to bother either of us. If you're a particularly light sleeper, you might want to look for something with more complete motion isolation, however. It's also worth noting that the mattress tended to cause me to roll inwards towards my partner (who is heavier than I am).
Motion isolation score: 3 out of 5
Edge support
Edge support is an important factor to look out for because a sturdy edge means that you'll be able to comfortably sit on / push up off a mattress when getting up, as well as being able to sleep right up to the edge. To test the Zoma Hybrid for edge support I placed my 10kg as close to the edge as possible – it sank 2 inches, which is slightly less than the centre. That's a good result.
(Image credit: Future)
I also tested out the edge support in a real-world scenario. I felt well supported when sitting on the edge of the bed, and also when lying right near the edge of the mattress when our toddler decided to squeeze into bed with us. Overall, I was impressed with the edge support here.
Edge support score: 4.5 out of 5
Zoma Hybrid mattress review: customer experience
Mattress delivered vacuum-packed and boxed; free delivery to door
Standard 10 year warranty and 100 night trial
Free old mattress removal in the UK
As a bed in a box mattress, the Zoma Hybrid is delivered vacuum-packed and rolled (if you're new to this kind of bed, read about the difference in our mattress in a box vs traditional mattress explainer). Zoma offers free delivery, but only to your front door. I can only speak for the UK delivery setup, but I was impressed with the company's communication – I received text messages a week prior to delivery (confirming delivery date) and then the day before delivery (with a more specific time slot).

It's a shame there's no option to upgrade to a delivery that includes setup – some bed brands offer this as a paid-for extra, and a handful even include it for free. Although the box was much more compact than a non-vacuum-packed mattress would be, it was still mega heavy and definitely needed two people to lift it.
There were no instructions or little pamphlets or even a little cutting tool to break the mattress free from the plastic wrapping. I found some scissors, and scored down the side of the plastic. The pressure of the vacuum-sealed mattress helped to force it out. Within a few minutes, the Zoma Hybrid was unwrapped and on the Livingstone Bed Base (also on review). It was pretty much ready to use straight out of the box, although the official advice from Zoma is to wait 4-6 hours before sleeping on it. There was no off-gassing.
If you're not entirely satisfied with your new Zoma Hybrid then you can return it, for free, after a 30-day period until the 100-night sleep trial ends. This 30-night mark stands because Zoma wants you to try it out for a minimum of a month to allow your body enough time to get used to it. Should you wish to return it within a month, you'll be charged $99/£79 shipping fee.
(Image credit: Future)
The 100-night trial is about the minimum offered by any of the big bed brands, although still long enough to try your mattress out thoroughly. Trials of 200 nights are fairly common now, and a few brands like Nectar give you a full year.
All Zoma mattresses also carry a 10-year warranty, which again is acceptable but not especially generous. During this time you're covered for a full repair or replacement, but the warranty only covers workmanship and structural defects – so no accidents.
An unusual perk is that Zoma offers free old mattress recycling. Old mattress removal is generally a paid-for extra, if it's offered at all, so this is good to see. In the UK, it's part of Zoma's commitment to sustainability – there, it repurposes all excess foam so there's zero waste to landfill. Any returned mattresses are recycled or refurbished. (This does not appear to be the case in the US.)

Zoma Hybrid mattress review: other reviews
4.8* average over 1,217 reviews (Mar 2024), US / UK reviews combined
High praise for comfort, breathability and motion isolation
Some complaints of it being too firm
At the time of writing, Zoma mattresses hadn't been available to UK customers for very long, so all the reviews that we're available to sift through are from the US. As of March 2024 there were a total of just over 1,200 reviews, the majority of which were 5 stars, and all sang the same tune about comfort and coolness. It's ordered highest scores to lowest, so you'll need to head to the latter pages for any complaints.
Here, I found a few reviews echo what I found. There are a few reviewers who found it too firm and uncomfortable for side sleeping, and found in led to aches and pains. One likened it to sleeping on a too-full air mattress.
Should you buy the Zoma Hybrid mattress?
Buy it if...
✅ You're a back sleeper: The Zoma Hybrid relieved pressure on achy muscles and joints when laying on our backs, with no sinking.
✅ You like a super-firm mattress: This is one of the firmest mattresses I've tested, rating 8.5 out of 10 on firmness. If you want a super-sturdy bed, this is it.
✅ Environmental impact is important to you: All Zoma mattresses are either made in the US or UK, depending on where you reside, and (in the UK at least) the brand has some admirable sustainability practices.
Alternatives to consider
❌ You're a side sleeper: The firm feel means most side sleepers will end up with pressure building up in their shoulder. I found it uncomfortable for side sleeping, and ended up having to shift onto my back. Other reviews reflect a similar experience.
❌ You weigh more than average: I found myself rolling towards the (heavier) weight of my husband in the night. If you share a bed and one or more of you is heavier in body weight then this isn't a great choice – our guide to the best mattresses for bigger bodies has some great specialist models.
❌ You want a joint-hugging feel: There's not much contouring here. If you want that body-hugging sensation, our guide to the best memory foam mattresses has plenty of recommendations.
Alternatives to consider
Rem-Fit 400 Hybrid mattress
The closest rival that I have tested to the Zoma Hybrid is the Rem-Fit 400 Hybrid. You'll usually pay around £450 for a UK double, so it's a fair bit cheaper than the Zoma. It stands for a similar purpose to the Zoma which is to help users 'recover'. I found that this mattress was far more comfortable for a side-sleeper, with reduced motion transfer compared to the Zoma.
Simba Hybrid Original mattress
I also vouch for the Simba Hybrid (UK-only). It's typically a bit pricier than the Zoma but worth every penny: fabulous edge-support, good motion isolation and superb support. Head to TechRadar's Simba Hybrid mattress review to find out more.
How I tested the Zoma Hybrid mattress
Myself and my husband slept exclusively on the UK king size Zoma Hybrid for four weeks. The review period coincided with a new house renovation, and the testing process was during February when there were some cold nights in the UK (when we had no heating) and warm nights (when the heating needed some fine-tuning). I also ran a series of tests to measure the edge-to-edge support and motion transfer.
The Saatva Graphite Memory Foam Mattress Topper is a three-inch thick, medium-firm topper from this well respected, luxury sleep brand. I slept on a king size topper for two weeks in February to see how it performs in practice, and how it compares to the rest of the best mattress toppers on the market.
Having written a Saatva Memory Foam Hybrid mattress review recently, and knowing that Saatva is the brand behind TechRadar's #1 best mattress, I was excited to test out this topper option. Saatva positions the Graphite Memory Foam topper as having “advanced cooling technology” and a “body hugging feel.” I found it delivered a cozy sleep experience, no matter which sleep position you prefer.
In addition to relieving some minor aches and pains, this topper will either improve your existing mattress' motion isolation capabilities, or at the least, maintain them. However, while it may be positioned as a cooling topper, I found it failed in this endeavor, which makes it hard to justify the high price tag.
A 180-night trial and free delivery sounds great, but be warned that you only get a one-year limited warranty and there is a $99 fee if you need to return it. All in all, if you’re more concerned with comfort than cooling properties, the Graphite Memory Foam Mattress Topper is worth the buy. However, hot sleepers should look elsewhere. Read below to learn more in my full Saatva Graphite Memory Foam Mattress Topper review.
3-inch-tall topper with memory foam infused with graphite
Organic cotton cover with antimicrobial treatment
Straps at corners hold it in place
The bulk of this Saatva topper design is CertiPUR-US certified memory foam infused with graphite, which provides a supportive feel, pressure relief, and cooling properties. The graphite, combined with an organic cotton cover that wicks away moisture and contributes to breathability, are the main cooling features. Although the topper can only be spot-cleaned, at least it has an antimicrobial treatment to prevent bacteria, mold, and mildew. (It's probably worth adding one of the best mattress protectors to make cleaning easier.)
(Image credit: Future)
This three-inch-thick mattress topper gave my 10-inch mattress some additional height. It blends naturally with my mattress and stays in place with four straps at the corners.

Saatva Graphite Memory Foam Mattress Topper review: price & value for money
Premium priced with a one-year limited warranty and 180-night trial
Not the most expensive or budget-friendly that Saatva offers
Rarely discounted
At $445 for a queen-size, the Saatva Graphite Memory Foam Mattress Topper is very much a premium mattress topper. Saatva offers another topper at the same price, two more that are cheaper, and one that’s more expensive.
Based on the materials, I can understand why it’s priced as a premium topper. However, when it’s touted as a cooling topper and doesn’t succeed in that department, I can’t say confidently that the price matches the quality. Here are the list prices for each size of the mattress.
On the larger market, it’s in the same price bracket (though slightly cheaper than) the Avocado Organic Latex Mattress Topper ($664 for the queen size). The Tempur-Adapt Topper has nearly the same MSRP, but there are semi-regular 40% off deals that make it much more affordable (head to TechRadar's Tempur-Adapt Topper review for more on that one) .
Medium firm and supportive feel for all sleep styles
Retains lots of heat
Improves edge support and has good motion isolation capabilities
While I have a supportive organic latex mattress (about a 5.5 on the firmness scale), the Saatva topper was slightly firmer. On a 10-point scale, I’d give it a 6.5 firmness rating as it had a cozy, body-hugging feel that was supportive, but not hard by any means. For reference, I’m 5'5" and weigh 170lbs. A friend who is smaller than me slept on the topper and agreed that it has a medium firm feel. She rated it as a 6.
(Image credit: Future)
While Saatva says that the Graphite Memory Foam Mattress Topper is best suited to side sleepers, I slept better on my stomach and back. In fact, it wasn’t until the second week that the topper had softened enough for me to sleep comfortably on my side.
I felt as if the topper reinforced the edges of my mattress, which is good news if you want or need a sturdy edge to help you get up in the morning. In addition, the topper also has great motion isolation capabilities. I tested this by placing a wine glass in the center, and then getting in and out of bed and changing sleep positions near the glass. The glass never wobbled.
(Image credit: Future)
Designed with memory foam infused with graphite and a breathable organic cotton cover, this mattress topper is supposed to offer top-tier temperature regulation. Unfortunately, it trapped so much heat that I slept uncomfortably, even with just a microfiber sheet covering me at night. I tested the topper in February and generally had to sleep with the fan on, especially after I woke up more than one night sweating. When a friend visited, I had her lay down on the topper on my bed and the first thing she said was, “Your bed is really warm.”
Vacuum-packed and rolled for delivery, but box not secure and heavy
While the mattress topper arrived by free delivery in a cardboard box, the box wasn’t secure. One of the cardboard flaps broke free of the paper tape. At least the box and tape were recyclable. The box was pretty heavy, but once I'd got it to my room, it was easy to remove the topper, which was rolled and vacuum sealed in plastic. The topper gained its full shape within a few hours, and yet, I noticed that the memory foam didn’t quite fill up the cover, leaving some wrinkles on the top.

... and on a bed just after being unpacked (Image credit: Future)
Upon removing it from its package, the topper had a noticeable woodsy, earthen smell. I don’t consider it an off-gassing or chemical smell, but I smelled the same thing when I previously tested a Saatva mattress. The smell was so overpowering on this topper (and caused my head to ache), that I couldn’t sleep on it for three days. After two weeks, the smell has now faded enough that it doesn’t disrupt my sleep. A friend of mine did not notice the smell after I had been using the topper for a week.
In addition to a 180-night trial, Saatva offers a one-year limited warranty, which is not typical for a premium topper. I’ve seen other luxury brands offer anywhere from three to 10-year warranties on their toppers – and Saatva itself has a forever warranty on its mattresses, so it's odd that its topper warranty is so stingy in comparison. Not to mention, it’s a little disappointing that there is a $99 processing fee to return the topper. I should also note that the brand doesn’t allow for exchanges – if you want to swap for another option, you must return the topper and then order a different one.

✅ You and your partner have different sleep styles: Neither you nor your partner will sacrifice good sleep as this topper will suit stomach, back, and side sleepers. Side sleepers may need to give their bodies a week to get used to it.
✅ Your existing mattress is very soft or very firm: This topper sits right in the middle of the firmness scale, which means it’ll firm up a very soft mattress or soften a very firm mattress.
✅ You want to know your mattress topper isn’t breeding mildew, mold, or bacteria: Thanks to an antimicrobial treatment, your topper will be free of mildew, mold, and bacteria – which is good since you can only spot clean this topper.
Don't buy it if...
❌ You sleep hot: For someone who doesn’t get warm or hot when they sleep, there were many nights where I woke up sweating while sleeping on this Saatva topper. The Brooklyn Bedding Microcoil Mattress Topper may offer a cooler night’s rest due to a 0.75-inch layer of micro coils.
❌ You want a super soft sleep experience: This topper is suited to stomach and back sleepers, so you know it has a medium-firm, supportive feel. The Tempur-Adapt Mattress Topper is known to offer a softer sleep experience.
❌ You’re on a budget: This is not a budget-friendly topper by any means. Save a pretty penny by going with the LinenSpa Gel-Infused Mattress Topper, which may result in a cooler sleep since it’s infused with gel.
How I tested the Saatva Graphite Memory Foam Mattress Topper
I slept on a king-sized Saatva Graphite Memory Foam Mattress for two weeks in February in Texas. There were a mix of cold and warm nights during that time, and while I generally sleep with a comforter and sheet, I had to forgo the comforter to sleep on this topper comfortably. Additionally, I had a friend sleep on the topper one night and provide me feedback.
The 1More Fit Open Earbuds S50 use air conduction technology to get sound to your ears. They don’t sit in your ear canal, like most other true wireless earbuds, or cover your whole ear, like over-ear headphones. Instead they’re designed to hook around your ears, positioning little speakers above your ear canals.
The benefits of this open-ear design is that you can stay more aware of what’s going on around you, which is ideal for outdoor workouts or anyone who doesn’t want to feel cut off from their surroundings. Because no part of the design goes inside your ear, they’re also a good option for people who don’t like the intrusive design of other types of buds.
Other audio brands have been venturing into air conduction tech recently, including Bose, Shokz and JBL. But, as I’ll get to soon, keeping earphones in place when there’s nothing inside your ear is a challenge: the 1More Fit Open Earbuds S50 won’t give the best earbuds a run for their money. It’s very difficult to get fantastic sound from this sort of design, but I was pleasantly surprised by their audio: it was clearer than I was expecting with some decent, but not powerful, bass.
They’re built for workouts with some specs you’d expect from the best workout headphones, like an IPX7 rating, making them sweat-resistant, and an impressive listed 38 hours of battery. I got around 35 hours during testing, so this is quite representative. The 1More Fit Open Earbuds S50 may sound like a decent set of earbuds, but they’re sadly let down by their fit: for me, they simply weren’t stable enough.
It’s easy to see why there’d be a problem with this design as in-ear buds are “anchored” in place when they fit in your ear canal. 1More attempts to solve this problem both with earhooks and small silicone rings, which sit just outside of your ear canal. However, the earhooks didn’t bend enough and were oddly-shaped for my ear. This meant I never got a good fit on my left ear, the bud fell out several times, and although I managed to get a slightly better fit on my right ear, the bud still felt precarious the whole time – not ideal for earbuds built for fitness.
Some of these fit issues could have been down to the size and shape of my ears, but I asked a few other people to test them and several had similar problems. Issues with stability became even more apparent when I was wearing glasses, too, as the earhooks and glasses were competing for the same small space behind my ear.

Cost $149.99 in the US
£149.99 in the UK
Around AU$290
The 1More Fit Open Earbuds S50 were released internationally in September 2023 and cost $149.99 / £149.99 / around AU$290. At the time of writing, they’ve been reduced on the 1More website to $99.99 / £104.99. We don’t know if this is a permanent discount or part of a limited deal.
1More also makes the S30, and while these earbuds use the same air conduction tech and have a similar design, they’re cheaper and a step down in terms of specs. They only have an IPX5 water-resistant rating and a 30-hour battery, compared to the S50’s IPX7 rating and 38-hour battery. The S30 cost $69.99 / £69.99 but, like the S50, are currently reduced to $47.99 / £49.99.
To put the S50 into broader context, similar air conduction rivals, like the Shokz OpenFit, are more expensive at $179.95 / £179.99 / AU$289, although I did find the Shokz buds to be generally better and much easier to wear. The S50 are more similar in price to JBL’s air conduction offering, the Soundgear Sense, at $149.99/£129.99/AU$231.
When comparing the 1More Fit Open Earbuds S50 to sports earbuds more generally, you can often expect to pay more for buds at the top of their game, like the Beats Fit Pro at $199 / £199 / AU$299. Then again, plenty of the options in our best workout earbuds guide are much cheaper and perform significantly better than the 1More buds, like the JLab Go Air Sport at only $30 / £29 / AU$69.

1More Fit Open Earbuds S50: Design
(Image credit: Becca Caddy)
Earhook design
Unstable fit
Looks nice and slickly designed
The 1More Fit Open Earbuds S50 use air conduction technology to enable you to hear audio, which means there’s nothing in your ear canal. Instead, a speaker is just outside of it. So what keeps these buds in place is an earhook design that fits behind your ear and little silicone rings, which 1More calls “sound loops”, that rest just above the ear canal. There are three different sizes of these loops to choose from to get the best fit. Rival buds have a similar earhook, but we’ve not seen the sound loop-like design anywhere else yet.
I get the thinking behind the sound loops: they’re a way to keep the buds in place without putting anything in your ear, which means you’re still aware of your surroundings. But they defeat the point of open-ear buds a little for me, as they are still using something to block your ear, even if it’s not as intrusive as a bud in your ear canal. I much prefer the design of the Shokz OpenFit.
But the reason the Shokz OpenFit work well without similar loops is that their earhooks are effective (albeit not perfect). Unfortunately, the 1More Fit Open Earbuds S50 have earhooks that are too rigid and not as ergonomic – at least not for my ears. This meant I never achieved a snug or stable fit with the buds, especially in my left ear. This bud fell out even when I was just walking and not working out.
I played with the earhook, adjusted the positioning, tried out all of the different loop sizes but had no luck. My best guess is that the distance between the bulk of the bud and the top of the earhook was just too big, so it actually fell down over the top of my ear. I did wonder whether this was a quirk of my ears and so enlisted a couple of friends and family members to see if they had similar problems. This was by no means an exhaustive test, but I found women with smaller frames had similar problems, either with one bud or both.
There was another problem that affected the fit: glasses. Even with my right ear feeling stable, wearing glasses meant the arm of my glasses and the earhook were competing for space behind my ear. I could either lay the earhook down first and put my glasses arm on top, which meant my glasses were unstable and vision ever-so-slightly distorted or the other way around, which meant the buds were even more unstable.
I opted to wear contact lenses for the rest of my testing, but some people won’t be able to. This also means wearing these buds and sunglasses could be an issue, which feels disappointing considering these are buds designed for outdoor workouts.
Despite these fit issues, these are a nice-looking pair of earbuds with a sleek design. I tested the silver version but, from what I can tell from online press shots, the darker grey shade is a little more appealing. The silver shade is nice, but does look a little cheap and plasticky. The same can be said about the charging case, which has a shiny cheap look about it. The charging case that comes with these buds is also big compared to the cases offered by competitors at 86 × 65 × 29.8 mm and weighing in at 63g (82.5g with the buds in). It could be slipped into a bag or a large pocket, but it’s not ideal for taking out on a run with minimal gear.

IPX7 water-resistant rating
Air conduction for ambient awareness
Good battery life
These earbuds are durable with an IPX7 sweat-resistant rating. This means they should handle the most sweaty workout sessions, even splashes, light rain and, technically, an accidental dunk in water. However, we wouldn’t advise it – and best keep them out of the shower.
There’s some opportunity to change the audio with 12 EQ presets within the 1More app. It’s good to have this option, but I preferred the way the buds sounded out of the box. You can also use the app to customize some of the touch controls on the buds. These didn’t work well for me as I never got a stable fit, so touching them made it more unstable.
The 1More Fit Open Earbuds S50 have what 1More calls its ‘PurePower Driver’ inside. The company says it has a diamond-like DLC diaphragm, which results in a 40% boost in power over conventional models. It’s not clear whether this means whether that’s over previous 1More models or rivals. There are also dual mics on each earbud for calls, and an AI algorithm promises to distinguish voices from background noises, helping block out any ambient sound when you’re on a call.
In terms of battery, 1More promises up to 11 hours of battery life from the buds and 38 hours of battery life with the charging case. I found these figures to be accurate during testing.
This is where the S50 really shine, bringing some of the best battery compared to rivals. For example, the Shokz OpenFit offer seven hours of battery life, and 28 hours from the case. And the JLab Go Air Sport (with an in-ear design) bring you eight hours with an additional 32 hours of battery life with the case.

Decent sound
Only some leakage
Great for hearing your surroundings
One of the biggest benefits of these open-style buds is that you can hear what’s going on around you, especially traffic, loud conversations and music. I personally found this to be a better experience than simply using the “ambient awareness” or similar modes on ANC headphones and earbuds, which I always find difficult to process.
However, due to the build of these buds – with their positioning and the silicone sound loops – not all sounds were clear in my immediate environment and it was easy to get distracted by the audio. This means you’ll need to be careful, as you definitely can’t hear everything when you’re using them. Especially when the volume is loud, which is worth bearing in mind if you run next to roads.
As you’d expect from an open-ear design, there’s some sound leakage. But not as much as I anticipated, which makes the 1More Fit Open Earbuds S50 a versatile proposition for wearing in a range of different environments – assuming you get a decent fit.
The S50 deliver a good but unremarkable sound. The audio is clear and there’s some decent bass and volume here too – again, two things I wasn’t expecting from the open-ear design. Push up the volume high on a bass-heavy track and things do start to sound a little muddied. Due to the style of these buds there’s also no real sense of immersion or an expansive soundstage. But then again, these buds were never going to be the best-sounding out there, you’d need to find a pair of the best ANC buds for a more polished experience. However, for me, the sound is perfect for providing a soundtrack to a walk or workout.

How I tested
I wore the 1More Fit Open Earbuds S50 most days over three weeks, and had the opportunity to test them in a range of different environments.
I used them while walking around the city and by the beach, running through the countryside and rollerblading. I took them to work at several coffee shops and the gym and wore them as I worked at home alone.
I also went on a trip to Rome whilst testing these buds, which gave me a good opportunity to use them in some different situations, like on a plane to listen to movies with my phone and in an airport to listen to podcasts and stay aware of flight announcements.
I paired them with an iPhone 14 Pro and mostly used Apple Music and Spotify streaming services to test them with music, as well as podcasts on Spotify and movies on Mubi.
I’ve tested many different headphones and earbuds over the past 12 years, especially those designed for fitness and active lifestyles. I like to find the devices that prioritize comfort and ease of use and flag up any new tech that feels more style over substance.
Suri Sustainable Sonic Toothbrush: One minute review
The Suri Sustainable Sonic Toothbrush tells you a lot about what it's aiming for right there in the name. However, there are other attributes to this powerful yet relatively affordable brush, that make it stand out from the many offerings now vying for your mouth space and the title of best electric toothbrush.
Primarily this is a company that prides itself on being sustainable, meaning it uses recyclable plant-based materials for the heads and bristles. But it also is designed with a simple aluminum frame that's made to be taken apart and fixed if necessary.
The company is so confident that you'll be pleased with what it offers that there is also a 100-day money-back guarantee – which applies to both the UK and US.
The brush is a sonic model, meaning it vibrates rather than oscillates. It also, quite uniquely, offers a carry case that features a UV-C light designed to give your brush head a bacteria-killing clean. A nifty feature that helps it compete even against the tech-crammed top-tier toothbrushes like the Oral-B iO Series 10 and the Philips Sonicare DiamondClean 9000.
Plus – and this is a tiny detail but shows the depth of thinking in design here – you get a sticky back magnet to attach to your bathroom mirror or wall, so the metal toothbrush can sit up and out of the way, keeping your sides clear and clean.
Suri Sustainable Sonic Toothbrush review: Price and availability

Priced at $92 in the US
£75 in the UK
AU$145 in Australia
The Suri Sustainable Sonic Toothbrush might not have been around for long, having launched in 2024, but it has been placed at such an ideal price point it is going to be appealing for a long time – especially if that price drops. It is available in the US, Canada, UK and Europe. It is currently priced at $92 / £75 / AU$145.
However, that is for the brush and charger alone, and if you want the case it will cost you extra. For the brush and UV case, the pricing is $116 / £95 / AU$185. The company says the brush is made to be easily repaired, so you shouldn't need another. Plus, if you do change up, Suri will recycle it all for free.
The heads are sustainable but are still going to wear down so you'll need to factor in replacement costs. A pack of three new heads will cost you $18.45 / £14.40 / AU$28. That includes fast and free shipping as part of the charge.

IP67 waterproof
Aluminium body
Sustainable, plant-based heads
When it comes to design, this is an area that Suri has worked on from the basics to the finished product with great attention to detail. This is because it had the goal of not only creating a great sonic toothbrush to compete with the big-name brands, but to do it all while remaining eco-conscious.
To do this, Suri used plant-based ingredients for its brush heads, from cornstarch and castor oil. These are shaped into a wave-shaped bristle pattern to take care of interdental cleaning. Plus the company will send these out with a return envelope so you can send them back for recycling.
The brush unit is made from an aluminum frame which lends it a solid and robust feel. The slender shape, thinner in depth than width, feels very comfortable in the hand and makes for a fine balance of weight, both in the hand and when standing up.
I found the included mount simple to set up, with a sticky back and magnetic front, yet it adds so much value. Stick it anywhere and your brush magnetically attaches – keeping your bathroom sides clutter-free and avoiding those black ring marks that most of the other brands leave on your bathroom sides.
The case is also worth shouting about as it not only charges the brush but also features a UV-C light to clean the head, but more on this in the features section. There is also an included puck-style charger base that plugs into a USB-style charging socket.
Suri has spent a lot of time and money refining the design of this toothbrush and it really comes across in the finish. Proof that sustainable and premium can be found in one sleek and sonic electric toothbrush-shaped package.

Suri Sustainable Sonic Toothbrush review: Features
(Image credit: Future)
Impressive 40+ day battery
Fast charging
UV-C cleaning light
Competing against the already established electric toothbrush competition in the forms of Oral-B and Philips was always going to be a challenge. But one way to really bring it to them is to offer better battery life – something that everyone nowadays appreciates, as one less gadget to charge is a relief. That's why this brush's battery life, which extends to beyond 40 days of use, is a really appealing feature. And, as if that wasn't enough, it also charges to full in just four hours.
The tricks keep helping this brush punch above the price point though, as that travel case is packing a UV-C light. This is a powerful light when it comes to cleaning as it will kill 99.9% of harmful bacteria in a single minute – a great feature especially when travelling. Plus the case charges the toothbrush, is sleek in its finish, and is minimal enough to take up very little room in a wash bag.
Of course, that case is part of the higher priced package – but even having the option to leave that, if it's not for you, in favor of saving a bit of money, is a thoughtful option.
The brush head itself features that wave design for superior cleaning, while the back of the head has a rubberized pattern that can make for the now-standard tongue cleaning with just the right amount of abrasion.
The main body is super minimal with a single button to power on and jump between modes. There are only two of these: Clean or Polish. The lack of modes sounds like a negative, but unless you need a softer mode for sensitive teeth, this can be more than enough. Since this is a sonic setup, it means you can go as gentle or hard as you need, so even the lack of a sensitive setting is probably an intentional choice from Suri.
There is a timer as standard, so you can get that recommended daily two minutes morning and night. This brush also features haptic feedback with vibrations at every 30 seconds so you have that guidance to move between dental zones – all pretty standard and expected of an electric brush at this price.
Features score: 4.5 / 5

Super quiet operating
High-speed sonics at 33,000
Brilliant battery
One of the standout features of this toothbrush is just how quietly it runs, at a meagre 54 db. This is barely noticeable. When you compare to oscillating brushes or premium sonic options, this undercuts them quite considerably – ideal for late-night brushing when a partner, roommate or parent is within earshot.
The brushing performance is above average standard. This is thanks to a combination of that brush head with the wave-shaped bristles of varying lengths that get in between teeth, and those sonic vibrations. The brush will vibrate at 33,000 times per minute which is ideal as a way to break down plaque and clean teeth more effectively than a manual brush, although the lack of oscillation does mean it's not as comprehensive as some of the ultra-premium brushes.
Usefully, when you switch up to Polish mode, you can feel the intensity increase, which allows you to put less pressure on while the brush does more of the work for you. This is useful for those who might struggle to maintain pressure for the full two minutes, or for anyone who wants to achieve a more effective clean without as much pressure on the brushing technique itself.
That battery life is also worth another mention since it's so effective. A four-hour charge time is fantastic. You can easily pop this on in the morning and you're good to go for your evening brush – or even a lunchtime clean if you're that committed. Then having a solid 40 days of use means you don't need to think about battery life for a good month or more.
Details like including the recycling packaging, to send heads back to the company, make it a more realistic process for most people, as does designing the brush to be easily repaired. This is potentially the last brush you need to buy for a very, very long time.

How I tested
I used the Suri Sustainable Sonic Toothbrush for weeks in order to test the effectiveness of the brush itself as well as that battery performance. I also visited the dentist during this time and was complemented on my cleaning efforts - reflecting well on this brush's performance.
I used the case for travel, over-night, as well as making use of the UV-C light cleaning feature. I mounted the magnetic holder to test its usefulness and was left surprised at how helpful this small addition was.
My brushing was twice daily with that two-minute timer and haptic half-minute guidance vibrations used to get a full and fair brush.
I was also testing other brushes from Oral-B and more which allowed me to see the difference between features like extra modes, oscillations versus sonics, battery life, screes, apps and more.
The Emma Premium Mattress Topper is a chunky, 9cm-deep foam topper that promises to boost in-bed comfort without trapping heat. I slept on this topper for two weeks to see if it could deliver on those claims, as well as to judge how it compares to the rest of the best mattress toppers on the market. We rate Emma to be among the best mattress brands on the market (discover the reasons for this in our Emma mattress review and Emma NextGen Premium review), so I was excited to see how this topper performed in practice.
Overall, I was impressed. While it isn't the right fit for me specifically, I believe it will be the ideal topper for certain groups of people. The two layers of foam deliver a plush, squashy feel that's great for lightweight people, some side sleepers, and anyone who is already a fan of a soft mattress. It's also thick enough to totally transform the feel of your existing bed. It's less well suited to heavier individuals and back or stomach sleepers, who (like me) might find the feel too soft, and lacking in support.
Price is another potential sticking point; it's fluctuated quite dramatically while I've been testing and writing this review, although it has remained in the premium price bracket. The quality and the fact it's thick enough to transform your existing mattress go some way to justifying the higher price, but there are plenty of cheaper options for those on a budget. Read on for my full Emma Premium Topper review.

Emma Premium Topper review: Design
Thick, 9cm depth topper with two different layers of foams
Polyester cover can be removed and washed at 40C
No straps or elasticated skirt to keep the topper in place
The Emma Premium Topper has a generous depth of 9cm. Unless your current mattress is pancake thin, it will probably require the purchase of extra-deep sheets. I added it to a 28cm mattress, with the topper taking things to slightly comical heights (I almost had to hop up into bed, and I'm not a short person).
Inside, you'll find two layers of foam: a thinner top layer of ThermoSync foam and a thicker bottom level of comfort foam. The uppermost foam is infused with graphite, to aid with temperature regulation (it also features in Emma's cooling mattress, which you can read about that in our Emma Luxe Cooling mattress review).
(Image credit: Future)
The cover is made from 98 per cent polyester and 2 per cent elastane, and it can be removed using the zip and washed at 40C – which isn't quite hot enough to kill off dust mites, but still helpful if you're prone to spillages. The cover isn't suitable for tumble drying, bleaching or ironing. I'd still be tempted to add one of the best mattress protectors, for even easier cleaning.
The base is made from a textured, slightly plasticky material. The topper is described as being flippable, but I'm pretty sure that's an error – I certainly wouldn't want to sleep on that base fabric. Although it's no good for lying on, the textured surface feels nice and durable, and does a good job of keeping the topper in place on the bed. This is good news, since there are no straps or other method of attaching it to your bed.
(Image credit: Future)
During my review, I topped it with a mattress protector with an elasticated skirt, and used a fitted sheet. All that, combined with the grippy base, kept the topper in place effectively. It all felt secure, and I never once had to reposition it during the two-week test period. I'm not sure how well it would fare just with a flat sheet, though.
The Emma Premium Topper is available in UK single, small double, double, king, and super king sizes. At the time of writing, there's one other topper in the Emma range – the Flip Topper, which is thinner at 6cm and can be flipped to give a softer or firmer feel. It's also very pleasing to say out loud.
Emma Premium Topper review: Price & value for money
Sits in the premium price bracket; price has fluctuated
At maximum price, almost as expensive as a full mattress
Thickness and quality of materials somewhat justifies higher pricing
Since I started writing this review, the Emma Premium Topper's pricing has changed quite considerably. At time of my original draft, a double cost £330, but by the time I was ready to publish, this had shot up to £419. Our premium price bracket for toppers is anything above £200 for a double, so it's definitely a pricey option. There are regular Emma mattress sales, but the toppers aren't usually discounted.
At time of publishing, here are the RRPs for the main sizes:
Single: £289
Small double: £349
Double: £419
King: £459
Super king: £509
The topper is thick enough to justify being in that premium bracket; it feels very well made, and it will totally change the feel of your bed. However, I'm not sure it's worth over £400. Some of today's best cheap mattresses cost less than that – in fact, a double Emma Original mattress is only slightly pricier.
Emma Premium Topper review: Comfort & performance
Squishy, sink-in, contouring feel
Thick, so will make your sleep surface feel unstable
Best for side sleepers and those who love a soft mattress
Emma's Premium Topper has a plush, squishy feel, and that softness is enhanced as a result of its thickness. The Emma brand is known for making some of the best memory foam mattresses around, and you're getting some of that magic here. The foam contours gently around the sleeper's joints, gently cushioning and relieving pressure.
Although the feel of a topper will be affected by what's beneath it, because this one is so thick, it has a pretty transformative effect. It's chunky enough to mask any lumps and bumps in an existing mattress – and if your bed is far too firm, then it will sort that right out, too.
(Image credit: Future)
I'm 5ft 8in tall, of average build, and typically go to sleep on my back but switch to my side in the night. I found this topper too soft to lie on for long periods on my back, as my hips sank too far in and left my back unsupported. It was more comfortable when lying on my side.
That all makes sense: the best mattresses for side sleepers are often a little softer, to prevent pressure from building up in the hip and shoulder while continuing to keep the spine aligned; back and stomach sleepers need something firmer, however, to maintain that neutral spinal position.
Some memory foams have a "quicksand" feel, where they're slow to respond to changes in pressure. That's not really the case here – if I press on the surface and remove my hand, it springs back quickly, and I'm not left with an outline of a handprint in the surface. However, the softness of the foam layers and the overall thickness of the topper mean that the sleep surface can feel a bit unstable, making it slightly tricky to change position.
(Image credit: Future)
I would be wary of recommending this topper to heavier individuals, since I often felt that I wasn't quite supported enough. This lead to aches and pains in the morning – maybe the result of shifting about on that slightly unstable surface, perhaps ending up twisting in a sub-optimal sleep position. However, if you're of lighter body weight, or generally just know you get on well with a softer mattress, then this plush topper may prove perfect for you.
Note, too, that the softness and thickness of the topper is particularly noticeable around the edges. Many mattresses come with edge reinforcements; that's never really a feature on a topper, with most shallow enough not to matter. If you need a sturdy edge to push up off when rising in the morning, you might get on better with a thinner or firmer topper.
(Image credit: Future)
A common issue with memory foam is that it can cling on to body heat, but I'm pleased to report that I didn't have any problems with the Emma Premium Topper running hot. I found it warmed to a neutral body temperature and stayed that way. I will add the caveat that during testing it was about the coldest overnight temperatures ever seen in my part of England – around -1C, or sometimes colder – so not the best conditions in which to test this properly. Even with that considered, I think the cooling properties of this topper are solid.
Emma Premium Topper review: Customer experience
Free delivery and returns, 100-night trial and 10-year guarantee
Vacuum-packed and rolled for delivery, but still heavy to move
The Emma Premium Topper arrived rolled and vacuum-packed in plastic, and in a box. I was surprised at how big and heavy it was. Many would be right to assume that a topper will be very portable; but at 9cm thick, it adds up to quite a volume of foam (I tested a double size).
Sometimes, foam bed-in-a-box mattresses give off an odour known as off-gassing when released from their wrappings. While harmless, it can be unpleasant. However, there was no reason for concern here: if I stuck my nose right into it, there was a faint "new mattress" smell, but nothing overpowering. Note that experiences can vary from person to person, even with the same product.
The trial period is generous at 100 nights. That's in line with the shortest full mattress trial periods.
Emma Premium Topper specs
Should I buy the Emma Premium Topper?
Buy it if...
✅ You want your mattress to be much softer: This topper is thick, and plush. You could probably lie it on a concrete floor and happily sleep on it.
✅ You're a lightweight side sleeper: This level of squishiness is best suited to side sleepers and those of light body weight. When lying on your side, the foam contours around your joints and prevents pressure building up in the shoulder.
✅ You have a bumpy old mattress: At 9cm thick, the Emma Premium Topper is deep enough to mask all manner of ills beneath it.
Don't buy it if...
❌ You lie on your back or stomach: This topper is likely to be too soft for most back or stomach sleepers, especially if they're on the heavier side. Generally, those positions require a medium-firm or firm feeling bed to keep the spine properly supported.
❌ You have mobility problems: The depth and plushness of the Emma Premium Topper means it will make your mattress super squishy, as a result making it difficult to change position. It will also make the edges of your bed softer and less supportive, which might be an issue if you like to sit on the edge of the bed or use it to push up off when getting up in the morning.
❌ You already have a deep mattress: At 9cm thick, this is one deep topper. Add it to an already thick mattress (such as mine) and your bed quickly starts to look ridiculous. You'll need deep sheets to cover both the topper and your mattress – and, depending on how tall you are and the height of your frame, you genuinely might have to end up having to hop into bed each night.
How I tested the Emma Premium Topper
I slept slept on the Emma Premium Topper every night for two weeks. I added it to a Brook + Wilde Elite mattress (firm feel) and used a thin mattress protector and fitted sheet, along with a duvet and cotton bedding. It was winter during my review period, and very cold overnight – temperatures dipped to -1C on occasion. The temperature in my flat was pretty warm, however.
The Garmin Forerunner 165 fills a necessary gap in its best running watches line. The very cheap Garmin Forerunner 45 and 55 watches are getting quite old, and the next stage up, the Garmin Forerunner 265 and Garmin Forerunner 965 watches, are much more expensive. So it’s nice to have an option in between those, even though we’d like to see a cheaper Forerunner 65 appear eventually.
Starting at $299.99 / £249.99 (with Australia pricing TBC), the Forerunner 165 is a middle-ground option that retains a lot of what makes the premium Forerunners really good training companions. It’s got the AMOLED touchscreen, the ace Morning Report feature introduced in last year’s Garmin Forerunner 955, and Nap Detection as introduced in the Garmin Venu 3.
You can also create Courses in the Garmin Connect app and sync them directly to the watch, and you get race-adaptive training plans, which suggest workouts based on historic exercise and recovery data. The design, meanwhile, is very reminiscent of the Forerunner 265, right down to the profile and the redesigned ‘run’ button. The whole thing is very appealing, especially at a reduced price point, offering genuine value in terms of features.
In order to achieve this, Garmin has made a few small sacrifices, such as using chemically strengthened glass for the screen instead of the 265’s stronger Gorilla Glass. The battery is a bit smaller than the 265's, and the watch has 4GB of storage instead of 8GB. It’s also missing a few features, such as the very useful Training Readiness score evolution of Garmin’s Body Battery feature, multi-band GPS (a big loss for a running watch) and compatibility with cycling power meters.

$299.99 / £249.99 / AU$ TBC
In comparison, the Forerunner 265 is $449 / £429 / AU$770
Music version costs extra
The Garmin Forerunner 165 is available now, priced at $299.99 / £249.99 / AU TBC. It’s good value, considering the 265 is much more expensive at $449 / £429 / AU$770. The older 255 is available for considerably less than the 265 these days, but you don’t get the Training Readiness score, nicer AMOLED screen or redesigned chassis.
The Garmin Forerunner 165 Music, which allows you to download and store songs and playlists from Spotify, Deezer, and Amazon Music, costs $349.99 / £289.99.

Similar chassis as the 265
Light and attractive
Bright screen
As mentioned, the Garmin Forerunner 165 shares a lot of DNA with the other Forerunners in the range. The classic Garmin five-button configuration is here, with the three buttons on the right-hand side used to navigate up and down, or wake the watch’s screen when its motion detector isn’t active. On the left are two more buttons: a start/stop button (labelled ‘run’ on the Forerunner series) and a back button for cancelling options or manually marking laps during a workout. It’s a tried and tested formula at this point, and Garmin isn't reinventing the wheel here.
The 1.2-inch AMOLED display is just as vibrant and bright as it is on the premium Epix Pro, which costs more than three times as much. However, Garmins are still training tools first and smartwatches second, and as such the 165 doesn’t have the smooth refresh rate that you might expect from, for example, the best Apple Watches. Nor does it have a more expensive-feeling metal backing: it’s all plastic and silicone, with the exception of the chemically-strengthened glass screen. There's no durable but pricey Gorilla Glass here, which is one of the sacrifices made to keep the Forerunner 165 at a cheaper price point. Still, it’s light and comfortable on my wrist, and it looks and feels good.
The user experience is the same as with most modern Garmin watches, with their list of widgets which you can easily navigate using either the touchscreen or the five-button system. It’s easily customizable, allowing you to add or reorder widgets as you see fit from Garmin’s library to tailor the watch to your own training style.
Garmin Connect is also one of the most comprehensive companion apps in the business, with a complex design that does require scratching the surface a little, revealing a wealth of depth and potential to elevate your training. I’ll go into this more in the Features section, but nothing’s changed here: if you liked the way previous Garmin watches operate, you’ll like this watch.
Garmin Forerunner 165: Features
(Image credit: Future)
Wrist-based running power
Morning report and Garmin Coach are great additions
No multi-band GPS or Training Readiness score
Garmin has added a lot of features here that I wasn’t necessarily expecting at this price point, such as wrist-based running power. ‘Power’ is an alternative method of calculating your effort that represents the total energy you’re able to put out, not just how fast your heart is beating or estimating how many calories you’ve burned. You used to need a specialist runner’s power meter measure this, as you can do for cycling, but Garmin has cracked the ability to show this number from your wrist.
Other features include the very useful Morning Report, which tells you how well-recovered you are and recommends a workout based on this stat; Course creation; and Garmin Coach, which can generate basic training plans depending on your goals. However, there's no Training Readiness score, which more accurately tells you how well you've recovered from your last workout, and this omission casts initial doubts on the accuracy of the Morning Report.
Another feature sorely missed here is multi-band GPS, which would have ensured greater accuracy when measuring speed and distance on runs. GPS is Garmin’s great selling point, so not providing the best is a missed opportunity, even at this price point.
However, at this lower cost, those interested in buying the Forerunner 165 are probably enthusiast runners who don’t care about pinpoint accuracy, and just want a good estimation. If that’s you, the loss of multi-band shouldn’t worry you too much, and the 165 is still shaping up to be a great running watch.
You do have to pay a premium for the Music version, which allows you to listen to your playlists by connecting your headphones to the watch directly, without using your phone. The Music version also offers guided workouts and performance alerts right from your watch to your headphones, which is very useful for adjusting your pace en route.
Garmin Forerunner 165: Early verdict
Garmin's latest running watch is shaping up to be a good buy. There's not much new here to critique in terms of the metrics Garmin is offering, and it is a little bit light and feels "toyish" thanks to the use of plastic instead of the tougher polymer used on more premium watches. However, it doesn't feel flimsy, and for under $300 / £250, it's a great way to grab a Forerunner at a reasonable price.
At present, I can see it being outdone by rivals such as the Coros Pace 3, which is also a plastic watch that's full of advanced features at a similar price point, but I can’t wait to dive into testing the GPS, advanced running features and battery life to measure it against that standard.
Leesa is a major player in online mattress retailers. The Leesa Studio mattress is its most affordable option, and has a simple design: it's 10 inches tall and contains three layers of different foams. I slept on a king size Studio for three weeks, as well as running a series of tests, to see how it compares to the rest of the best mattresseson the market.
Many customer reviews rate the mattress as a moderately firm feel, and I agree – it's around an 8 out of 10 on firmness. Although the mattress begins with a top layer of memory foam, don't expect to sink in and have your body enveloped in the foam. There is some contouring, but when I press down on the mattress with my hand, the mattress snaps back into form in about a half second.
Not to say that it's like sleeping on the floor – it's still comfortable – but having tested several mattresses over the years from brands like Purple, GhostBed, Saatva, Brooklyn Bedding and others, this is the firmest mattress I've experienced. I found that sleeping on my side on this mattress led to a build-up of pressure in my shoulder, and I expect that will be the case for most side-sleepers.
However, the firmer feel makes it a great choice for those who sleep on their back and stomach, and it might also work well for those suffering from back pain. For context, I used to be a stomach sleeper, but eventually had to switch to sleeping on my side due to lower back pain. When I laid on my stomach for extended periods of time on the Leesa Studio, I didn't experience any of that familiar pain. For me, it's amongst the best mattresses for back pain.
There are a couple of caveats to that. Because it's fairly thin, it probably won't suit those who weigh over 200lbs, and I also had issues with it running warm. If you're a naturally hot sleeper, the Studio won't work for you. Read on for my full Leesa Studio mattress review.
Leesa Studio mattress review: price & value for money
The cheapest Leesa mattress, and lower mid-range overall
Rarely sold at MSRP – expect 25% off
Free pillows usually bundled in
The Studio is the cheapest mattress in the Leesa range, but it sits in the lower-mid range price bracket overall. That's based on the regular discounts, because you'll never really pay full MSRP at Leesa. Expect around 25 per cent off, with two free pillows. Here's the pricing for the main sizes when you buy direct from Leesa:
Twin size: MSRP $549 (usually sold at $412)
Full size: MSRP $699 (usually sold at $524)
Queen size: MSRP $799 (usually sold at $599)
King size: MSRP $999 (usually sold at $749)
We'd always recommend buying direct from the brand wherever possible, to make customer service easier. However, the Studio is also available via the Leesa Amazon store. Pricing will usually be the same but it's worth double-checking before you buy, to make sure you're not missing a bargain.
All-foam mattresses tend to be the most affordable mattress type, which means there's tough competition in this price bracket. The top two models in our best memory foam mattress ranking both generally cost around $699 for the queen size. Read about those in our Nectar mattress review and Cocoon Chill mattress review.
10-inch tall memory foam mattress with three layers of foam
Lightweight for a mattress, king weighs only 83lbs
Cover has a zip but shouldn't be removed; no handles
The design of the Leesa Studio is simple but effective. Inside of the soft, removable mattress cover is three layers of foam. At 10 inches tall, it's on the thinner side, and also pretty lightweight. The king-sized mattress that I tested only weighs 83lbs. For reference, a king-size Purple mattress weighs 120lbs. So, if you ever need to move the mattress from one bedroom to another, or from one home to another, it won't be too heavy to deal with.
(Image credit: Leesa)
All three layers of foam are CertiPUR-US certified. This means the foam was tested by a third-party to ensure that no harmful chemicals are present in the foam and that it meets durability standards to last the lifetime of the mattress. Inside of the mattress cover begins with a 1.5 inch layer of memory foam. This layer is designed to provide a sink-in contouring feeling. Below the initial memory foam is another 1.5 inch layer of responsive foam. This is an airy foam designed to help dissipate heat and keep you cool during your sleep.
(Image credit: Future)
Finally, a 4-inch layer of base foam provides the support for the mattress. Essentially this provides firmness and stability, so you don't simply sink through the top layers into the platform, which wouldn't be comfortable at all.
The look of the cover is recognizable, clean, and modern, making it look appealing standing alone on laundry days when it's time to wash bedding. There is a zipper, so you could take the cover off, but Leesa doesn't recommend it. Adding one of the best mattress protectors is always a good idea, anyway. Overall, it's a simple bed design that's lightweight and easy to move around, even though the mattress doesn't have any handles.

Leesa Studio mattress review: comfort & support
Most comfortable on back or stomach sleeping positions
Light sink in, returns back to form in about half a second
May be too firm for side sleepers
When you scroll through the purchased views on Leesa's website, virtually the only complaint about the mattress is that it is more firm than people expected. I can say that's exactly what my wife and I experienced after sleeping on the bed for a few weeks. I would rate the firmness an 8 out of 10. Leesa rates the mattress as a medium/moderately firm mattress, which is about on-par with my assessment, and the assessment of many customers. Compared to the mattress we were previously sleeping on – a pillow-top, spring mattress – the Studio is a much firmer feel, and it took a few nights for our bodies to adjust.
When I placed a 25lb weight and in the middle of the bed, it sank in roughly 1.5-inches. The mattress returns to form about a half second after the weight is removed. I had two others try out the mattress, and they, like me, reported a responsive feel with minimal sink and just a tiny bit of contouring.
(Image credit: Future)
I weigh about 155lbs and I used to sleep on my stomach, but with my old mattress, I had to switch to my side because stomach sleeping was causing lower back pain. When I lie on my side for too long on the Leesa Studio, I wake up with a sore shoulder. My wife, who is much smaller than me, has the same issue; both of us have noticed that even if we fall asleep on our sides on this mattress, we end up on our backs by the time we wake up. A third member of my testing panel, who weighs just north of 200lbs, also found the mattress to be too firm, and lacking in pressure relief, especially when they laid on their side.
The best mattresses for side sleeperstend to be a bit softer, and often come with higher levels of contouring, to prevent pressure building up in the shoulder. The Leesa Studio doesn't offer enough contouring for most side sleepers.
(Image credit: Future)
However, it's pretty well suited to back and stomach sleepers. Generally, these positions require a medium-firm or firm mattress, to keep the sleeper's back supported and prevent the pelvis from dropping too far into the surface and putting strain on the spine.
Even though I generally try and avoid rolling onto my stomach because of my back, while testing the Leesa Studio mattress I found myself getting comfortable again on my stomach, and without back pain. On my old mattress, when I would lay on my stomach, I could feel my back starting to bark within a couple minutes. On the Leesa Studio, there is plenty of lower back support to keep your lower back/stomach from sinking in and causing pressure that leads to discomfort or pain. (If you like the sound of a sturdy sleep surface and want to see what else is out there, our best firm mattress guide rounds up our favorite options.)
Leesa Studio mattress review: performance
Does not dissipate heat well
Negates some motion transfer
Slightly more sink on edge compared to center
I slept on the Leesa Studio mattress for three weeks during the coldest month of the year in northern Utah (January), with lows in the teens (Fahrenheit). During this time, I tested the mattress following TechRadar's mattress testing methodology. Read on to find out how this mattress performed.
Temperature regulation
I am a hot sleeper and my wife is a cold sleeper; I go to bed in gym shorts while she is fully clothed in bed. I found, even in the dead of northern Utah's coldest month, that I was getting hot at night. My wife did as well, saying that she didn't feel the need to 'layer up' before she went to bed anymore.
(Image credit: Future)
In short, this bed is not ideal for heat dissipation. Living in a dry climate that is especially cold right now, it makes me skeptical that I would be comfortable come summertime on this mattress.
Temperature regulation score: 2 out of 5
Motion isolation
One of my biggest complaints about my normal mattress, which is a spring mattress, is motion transfer. Our 50 pound dog sleeps with us (don't judge me), and I can feel every micro-adjustment he makes in the bed. The Leesa Studio all but eliminates that problem. My wife also mentioned she no longer feels when I get up to go to the bathroom in the middle of the night.
(Image credit: Future)
For an objective idea of how well this mattress isolates motion, I used a travel mug and dropped a 25lb weight from about 6 inches onto the mattress at varying distances away from the mug to measure motion transfer. Once the weight was about 9 inches away from the mug, the mug stopped falling over.
Motion isolation score: 4.5 out of 5
Edge support
Edge support is important for those who have trouble getting in and out of bed. A mattress that doesn't have proper edge support will be more difficult to climb in and out of – you might feel as though the bed is sinking and you're sliding out.
(Image credit: Future)
I placed my 25lb weight on the edge of the bed to measure the sinkage. Remember, the middle of the bed recorded roughly 1.5 inches of sinkage. On the edge of the bed, the sinkage recorded was closer to 2 inches. When I sat on the edges of the bed I felt myself slightly sliding out of the bed. I do still feel supported – the bed isn't collapsing under my weight – but there is definitely a bit more give. When I lay on the edge of the mattress, I don't feel any sensations of rolling off. Edge sleepers shouldn't be concerned about rolling out of bed, and getting in and out of bed wasn't difficult, although there was a little more give than expected.
Edge support score: 3.5 out of 5
Leesa Studio mattress review: customer experience
Free standard delivery to doorstep
In-home setup and old mattress removal available for a fee
Standard 100 day free trial and 10 year limited warranty
You can request at checkout in-home delivery and old mattress removal. In-home delivery and setup costs an extra $159, while adding old mattress removal bumps it up to $199. All you need to do is ensure the bedding is removed from your old bed and the delivery company will either donate or dispose of the mattress sustainably.
Without those add-ons, the Leesa Studio arrived on my front doorstep rolled up, wrapped in plastic and boxed. Since the king mattress is lightweight and only weighs 83lbs, it was quick and easy for two people to move the mattress to the bed.
(Image credit: Future)
Once the mattress was on the bed, I unrolled several layers of plastic and the mattress started to expand even before all of the plastic was fully removed. The mattress seemed to be fully expanded after only 10 minutes or so. Once fully expanded, there is a slight plastic-like smell, but that smell was mostly masked by the fitted sheet, and completely unnoticeable after a day or two.
(Image credit: Future)
Leesa offers a 100-day trial period and a 10 year limited warranty on the Leesa Studio. This is considered industry standard in terms of trials and warranties (some brands, like Nectar, are more generous, and give you a full year's trial and forever warranty). In order to be eligible for a return, you must have the mattress for at least 30 days, but no longer than 100. Leesa will encourage you to donate the mattress to a charity, but if that is not an option, you can call its return phone number and begin the return process. There are no fees associated with returns unless you live in Alaska or Hawaii, in which a $100 return fee is included.

Leesa Studio mattress: other reviews
When it comes to customer reviews, the majority of the people are pleased with the purchase. You'll find a lot of 'best night sleep ever' from a number of user reviews on Amazon or Leesa's website.
As I alluded to previously, the user reviews on the Leesa website provide an overall 4.2 star rating based on 58 reviews. The main culprit of complaints is the firmness of the mattress. Many users claim that it's firmer than the 'medium firm' rating provided by Leesa. Even users who left positive, four-star ratings leave comments noting the firmness of the mattress.
At time of writing (Feb 2024), the mattress had received a 4.4 out of 5 star average rating on Amazon. Again, many of the most common complaints are about the firmness of the mattress, or if you are heavier than 200lbs, the mattress may not be supportive enough. I also found other reviews that mentioned the mattress being ideal for users under 200lbs. I did also find a few mentions of users accounting for the mattress sleeping hot. I had a similar experience, as noted above, and it appears other users second those experiences.

Should you buy the Leesa Studio mattress?
Buy it if...
✅ You're a back / stomach sleeper: The firm (8 out of 10) feel makes this a good choice for those who like to lie on their back or stomach. These positions require a sturdier feel, to keep the pelvis supported and ensure
✅ You suffer from back pain: While my usual, softer mattress can aggravate my lower back pain when lying on my stomach, I didn't have that issue when testing out the Leesa Studio. I think that's down to the firmer, more supportive feel.
✅ You're a cold sleeper: Heat retention is often considered a bad thing with mattresses, but my wife – who is a cold sleeper – found the fact that this mattress retains body heat was a benefit. It meant she didn't need to bundle up at night. .
✅ You share a bed: The Studio does a good job of absorbing movements on its surface, which makes it a strong choice for bed-sharers, especially if they're easily disturbed at night.
Don't buy it if...
❌ You are a hot sleeper: If you're searching for a mattress to help keep you cool at night, the Leesa Studio may not be for you. I found it ran warm at night. TechRadar's best cooling mattress guide has plenty of alternative options – the top rated one is the Purple mattress, which I also tested and was the coolest mattress I've ever slept on.
❌ You are a heavier (200lbs+) person: There are many user reviews across the web that mention that this bed isn't supportive enough for heavier individuals. Something like the DreamCloud Hybrid mattress might be a better choice, or if you weight 250lbs or more, consider something built especially for bigger bodies – TechRadar's guide to the best mattresses for heavy people has our top picks.
❌ You are a side sleeper: Everyone who slept on the Studio for this review has issues with pressure building up in their shoulder when lying on their side. Something more contouring, such as the Nectar Memory Foam mattress, will be a better fit for most side sleepers.
How I tested the Leesa Studio mattress
I slept on the Leesa Studio mattress for three weeks during the coldest month of the year in northern Utah. Utah has a dry climate and during my testing, the lows were in the teens with highs in the 30s (fahrenheit). I used our normal bedding, which for us, consists of a mattress cover and comforter (my wife nor I sleep under a sheet). The bed was occupied every night by me, my wife, and our three-year-old, 50lb Aussiedoodle.
Standardized testing included sinkage testing, where I placed a 25 pound weight in the middle of the bed and measured how much the mattress sunk. For edge support, I placed the same weight on the edge and end of the bed and measured how much the mattress sunk. For motion transfer, I placed a travel mug on the bed and dropped the 25 pound weight from varying distances to see how well the mattress eliminates motion transfer.
The Naturepedic Adagio 2" Organic Latex Mattress Topper is a foam mattress topper that adds softness to your existing mattress. Even a good quality, supportive mattress isn’t always as soft and comfortable as one would like, so a plush mattress topper can add a great deal of comfort. This one isn’t cheap, starting at $499 for a twin size, but I found it to be one of the best mattress toppers you can buy. I had a 'wow' moment the first time I laid down on it.
The Adagio is basically a two-inch thick rectangle of foam encased in fabric that sits on top of a mattress, and it's a fantastic way to turn a too-firm mattress into a softer one, relieve pressure points, and maybe even improve your sleep.
(Image credit: Future)
I tested it for a week. I sleep primarily on my side, but I also sleep on my back and spend a lot of time reading in bed on my back as well. My husband helped me test this mattress topper, and he’s mostly a stomach sleeper. The Adagio feels plush to the touch, and is designed specifically to relieve pressure points. In my testing, I found that it really does the job.
I’d recommend this for anyone with a medium to firm mattress that wants to add a bit of softness, regardless of sleep position. The latex foam doesn’t trap heat, it just adds gentle, pillowy cushioning to your mattress. Additionally, its materials are certified organic by the Global Organic Textile Standard and are sourced from reputable certified suppliers. This ensures purity, fair labor practices, and support for rubber tree forests.
Cover is made from organic cotton stretch knit fabric
No skirt or straps to hold it in place
The Adagio is made from organic latex sourced from rubber tree sap. It has holes throughout that keep it from trapping body heat. This latex is approved by GOTS, the Global Organic Textile Standard, for use in certified organic mattresses. It’s also sourced from reputable certified suppliers, ensuring fair labor practices, product purity, and protection for rubber tree forests.
(Image credit: Future)
The cover is a soft, stretchy, organic knit cotton fabric. The materials combine to make an extraordinarily soft and comfortable sleeping experience. However, even if you could fit this sizable topper into your washing machine, it is not washable at all. You can only spot clean it.
One thing worth noting is that the Adagio topper simply sits on top of your mattress, without any skirt or straps to hold it in place. While I didn't have any problems with the topper sliding out of place during my review period, it feels likely that over longer periods of time you'll like have to adjust it back into place, particularly if you or your partner tend to move around a lot in the night.

Naturepedic Adagio Latex Mattress Topper review: price & value for money
Premium mattress topper
Prices range from $499 (Twin) to $849 (King)
Not always discounted
With prices starting at $499 for a twin and going all the way up to $849 for a king size, the Naturepedic Adagio is certainly a premium mattress topper. Here's what it costs at MSRP:
Twin: $499
Twin XL: $549
Full: $649
Queen: $749
King: $849
Cal king: $849
$749 for a queen size topper is a lot of money; you'll pay less than that for some of the best mattresses. Naturepedic often runs 20%-off deals, which means entering a coupon code at the checkout. It's not hugely intuitive and it means you might assume that there's no discount on the Adagio, but I've just checked and it's currently possible to get 20% off, bringing the price of a queen to a more palatable $599.20.
You can certainly save money choosing a cheaper mattress topper. The Puffy Deluxe Mattress Topper is TechRadar's top pick, and it starts at just $179 for a Twin, which still puts it in the luxury category but it’s substantially cheaper than the Naturepedic Adagio. Our reviewer noted how well it conformed to and cradled her joints in all sleeping positions but noted that it sleeps hot.
If you’re looking for more options, the Turmerry Latex Mattress Topper comes in three different thicknesses and four levels of firmness. It starts at just $150 for a twin, so it’s a more affordable option. Another alternative is the Avocado Organic Latex Mattress Topper; it's 2.75" deep and comes in firm and plush options, and at MSRP a queen size is $100 cheaper than the Adagio.
The Naturepedic Adagio 2” Organic Latex Mattress Topper is soft, and intended to be used over a medium to firm mattress. It’s not adjustable at all, it just is what it is. My mattress is firm with a pillow top, which is pretty comfortable on its own, but this Adagio adds a whole other level of cloud-like softness and pressure point relief. Neither my husband nor I are big people, we both found that this added a great deal of comfort to our mattress.
(Image credit: Future)
I usually sleep on my side, but sometimes sleep on my back. I also spend a great deal of time reading in bed, on my back. With just a mattress, I often feel some pressure in my hip area in both of those positions. The Adagio topper eliminated that completely. My husband is a stomach sleeper, and he felt supported and quite comfortable as well.
Naturepedic mentions on its website that the Adagio mattress topper 'sleeps cool'. While I didn’t notice any cooling sensation, I didn’t notice it trapping body heat, either. As a woman in midlife, I’m quite sensitive to anything that can trap heat, and I didn’t have any such issues with this topper.
(Image credit: Future)
I found it very comfortable to sleep on, temperature-wise; for me it remained temperature neutral all night long. My husband also tends to sleep hot, and he had no issues either. I used nothing but a microfiber fitted sheet between me and the Adagio topper, plus a flat sheet and light quilt over me. I tested the topper during the winter, with the interior thermostat set on 68 degrees.
Free delivery and returns, 100-night trial and 10-year warranty
Heavy but otherwise easy to set up
No noticeable off-gassing smell
The Adagio topper comes with free shipping in 1-3 business days within the continental US. When mine arrived it was so heavy that I had to enlist the help of another person to bring it into my home and upstairs to my bedroom. The topper was rolled and vacuum-packed with several layers of plastic, and packed in a large box. Once unpacked, it was easy enough to remove the plastic and unroll it onto my mattress. This took just a few minutes but there was quite a bit of cardboard and plastic to dispose of.

Once unrolled, it took only a few more minutes for the topper to regain its full shape and thickness. There was no noticeable off-gassing smell, and the topper was ready to use virtually right away.
As well as free delivery, the Naturepedic Adagio topper comes with a 100-night sleep trial, giving you plenty of time to judge whether it's the right addition to your mattress. Naturepedic also offers free returns, and the Adagio comes with a 10-year limited warranty for additional peace of mind.

❌ You're on a tight budget: Even with a discount this is an expensive topper, and while many will happily pay for its luxurious feel, there are cheaper options available. The Turmerry Organic Latex topper is more basic but offers a similar feel for a much lower price.
❌ You're a clean freak: If you want the ability to wash your mattress topper, the spot clean-only Adagio isn't for you. Consider instead the Tempur-Adapt mattress topper: a soft and supportive premium topper that's incredibly comfortable and also boast a washable cover.
❌ You move about a lot in the night: Nocturnal wrigglers are likely to find that the Naturepedic Adagio doesn't stay put for very long, because it sits on top of your mattress with nothing to hold it down. The Saatva Foam mattress topper will transform the feel of your bed in a similar way, and features hefty straps to keep it secure.
How I tested the Naturepedic Adagio 2" Organic Latex Mattress Topper
I tested the Naturepedic Adagio 2" Organic Latex Mattress Topper on a firm mattress with a pillow top, over the course of a week in winter, with the thermostat set on 68 degrees Fahrenheit. I slept on it in on my side and on my back, while my husband tested it while sleeping on his stomach.
The Circular Ring Slim is a smart ring packed with sensors. It’s designed to be worn 24/7 and collects data about your heart rate, breathing, temperature, SpO2 levels, sleep, steps and more. Unlike other smart rings, it has a vibrate function too, enabling you to set alarms. Think of it as a fitness tracker designed to collect data from your finger, rather than your wrist.
Data collected is presented as scores and charts in the accompanying app. Over time, the app will get to know you better and present information about your health and fitness and also make recommendations, such as the best time to eat and when you should avoid blue light in the evenings.
Right now, there are several similar devices available, such as the Oura (generation 3) ring and the Ultrahuman Ring Air, which we’ve reviewed in our guide to the best smart rings. The smart ring market is set for a serious shake-up with Samsung’s smart ring, the Samsung Galaxy Ring, officially on its way, and no doubt there will be others. However, they’re not easy devices to make, and in my opinion I don’t believe they’re a suitable option for most people. In fact, I’d recommend sticking with one of the best fitness trackers – at least for now.
On paper, the Circular Ring Slim offers everything it needs to compete with rival brands. It looks and feels decent, collects a variety of data, and offers genuinely useful insights. But in practice, the Circular Ring Slim needs improving. The exterior scratches easily, battery life is disappointing, and the app is confusing – especially with regards to the journey it takes users on, and the way in which instructions and insights are worded.
Circular could easily fix some of these problems; indeed, it wouldn’t take much to make the app more user-friendly. Circular is also working on improving the exterior of future versions of the ring, making it more resilient to scratches. However, the battery is a major issue, running out of juice in just two days and, at times, reducing performance as it did. Sure, some might already have become accustomed to charging their wearable devices more regularly – I’m looking at you, Apple Watch – but for a health tracker without a screen that’s designed to be worn 24/7, two days doesn’t feel sufficient.
I applaud Circular's solid effort with the Ring Slim – a more basic and affordable version of the brand’s Ring Pro. However, read on for a more in-depth review of the Circular Ring Slim, and to discover the reasons I think its rivals are ahead, delivering more appealing, wearable devices and an overall better experience.

Costs $264 (about £209 / AU$405)
Released in early 2024 in batches
The Circular Ring Slim costs $264 (about £209/AU$405) and ships internationally. Released in early 2024, Circular has been taking pre-orders in batches. At the time of writing, it’s out of stock on the Circular website, but the brand promises a new drop soon.
One of the main features that sets the Circular Ring Slim apart from one of its key competitors, the Oura ring, is that the device doesn’t require a subscription. So if you’re looking to test the waters, then this is probably a better option than investing in a model that requires you to pay out on a monthly basis.
Also competing for your attention in this space is the Ultrahuman Ring Air. Like the Circular Ring Slim, this model doesn’t follow a subscription model either and is therefore a more direct rival to the Circular smart ring. At the time of writing, it costs $349 (about £276 / AU$536). It’s more expensive, then, but it does beat the Ring Slim in almost every way, especially with regards to battery life and app experience – although be aware that it’s just as prone to picking up scratches.
Circular also offers the more expensive Circular Ring Pro, which at $364 (about £288 / AU$559) positions itself against the Ultrahuman Ring Air, but we haven’t had a chance to put that to the test yet.
Compared to the two of its biggest rivals, the Circular Ring Slim is cheaper then; but this doesn’t necessarily make it better value. It's also worth mentioning that you can collect much of the same data from a more affordable fitness tracker, such as the Fitbit Luxe at only $109.95 / £109.99 / AU$199.95. Sure, the Fitbit form factor might not be as fun or exciting, but as you’ll learn throughout the rest of this review, it’s probably far more reliable and a better option for the majority of people.

Circular Ring Slim: Design
(Image credit: Becca Caddy)
Slim and comfy
Scratches easily
White logo cheapens the design
Circular says that the Ring Slim is made from aluminium and carbon fibre on the exterior and an unspecified medical-grade, non-allergenic and non-metallic material on the inside.
With an IPX8 rating, the Ring Slim is water-resistant to a point; it can handle being submerged in 1.5 meters of water for 30 minutes. This means it should be fine for hand washing and showering, but I wouldn’t risk wearing it while swimming, and Circular says it isn’t recommended for wear in the sea, either. While this rating won’t be an issue for most people, given that smart rings are designed for active people and all-day wear, it’s worth bearing in mind for those who swim regularly.
At 2.2mm thick and weighing 2g, the Ring Slim is available in 8 sizes, from US 6 to US 13 – and you can get your hands on a sizing kit to ensure you get the right fit. Circular states on its website that the Ring Slim is the “thinnest” tracker – but its only 0.2mm slimmer than the Ultrahuman Ring Air, and in a side-by-side comparison (see photo below), this isn’t noticeable. Note, too, that while the majority of the ring is super slim, the section where the sensors sit is quite chunky.

Nevertheless, the Circular Ring Slim is comfortable to wear. I wore it for most of the day over six weeks and didn’t really notice it on my finger. The interior is smooth enough not to irritate or pinch, and the ring is incredibly lightweight.
However, it doesn’t have the hypoallergenic epoxy resin coating of the Ultrahuman Ring Air; wearing both models together for a week did point to the Ring Air being slightly ahead for comfort. Regardless, considering most will be unlikely to have both to compare, they’ll be more than happy with how the Ring Slim feels on the finger.
The matte black finish looks super slick when you first take the Ring Slim out of the box. However, following just a couple of days of wear, the ring was already showing mild scratching on the surface and around the edges (see the photo below). This isn’t unexpected; I had similar issues with the Ultrahuman Ring Air. However, considering I took many precautions to ensure this wouldn’t happen – namely removing the ring when I had to grip anything at the gym – it’s a shame the ring showed wear and tear so easily.
I spoke to Circular’s PR team, who said: “They [Circular] are aware that the first batch of rings are a bit more prone to getting scratched, but they have worked on it to improve that for the next batch of Ring Slim.” Let’s hope Circular’s future offerings of the Ring Slim also include different finishes because I think matte black is a tricky finish for this kind of wearable.
The little white Circular logo is an unexpected design choice on the Ring Slim. This presumably ensures you have the ring on the right way round, with the sensors on the inside of your finger to ensure accurate data collection while the logo is positioned on the outside.
In my opinion, the white logo cheapens the look of the ring – and it’s confusing given that it doesn’t appear on all of the images of the smart ring in Circular’s promo material, either. In fact, when I shared an image of the Circular Ring Slim on my Instagram Stories when it first arrived, I had a concerned customer who had pre-ordered a ring get in touch, who hadn’t seen the white logo before and didn’t like it. Proof that I’m not the only one who thinks the white logo isn’t in keeping with the rest of the Ring Slim’s design.

Real-time measurements
Packed with sensors
Kira assistant makes smart recommendations
The Circular Ring Slim does come packed with sensors, which it uses to track and collect data about you through the day and night. You can also take real-time readings, including heart rate, heart rate variability, SpO2 and activity intensity. Compared to the Ultrahuman Ring Air and my Apple Watch, I found these to be accurate.
One unique part of the Circular Ring Slim offering is that it can vibrate. Surprisingly, I didn’t use this feature much during testing, even though I found it quite a cool addition. It makes me wonder whether this sort of tech without a screen should just be “passive”, a set-it-and-forget-it kind of tracker, without all the bells and whistles. Something in-between – a smart ring with vibrations, for example – felt different and unnecessary. Although, I’m aware this is likely to come down to personal preference. Plus, when I did try out the vibrating feature as an alarm to wake me up in the morning, it worked well.
Another feature that makes the Ring Slim stand out is what Circular calls Kira. This is branded as an “AI assistant” that learns more about you over time to then offer personalized insights. However, this isn’t explained particularly well; you’re simply told that for 14 days the ring is calibrating.
Of course, I understand the reasons for having a calibration period, but Circular has made this process unnecessarily confusing. Insights were thin on the ground until the 14-day period was over, and during that time, I was expected to answer some very long and convoluted questions. With clearer explanations and simpler questions, it would have felt less like I was trying to solve a riddle.
Importantly, once the calibration period had passed, the insights delivered were genuinely useful. They included suggestions such as the best time to eat dinner each day, and when you should avoid exposing yourself to blue light.

Circular Ring Slim: Performance

Confusing app
Syncing issues
Only 2 days of battery
In terms of data collection, the Circular Ring Slim performed well, collecting information about heart rate, breathing, temperature, SpO2 levels, sleep, steps and plenty more.
For example, you’ll get a detailed breakdown of your sleep stages, your heart rate overnight and temperature, too. You’ll also get cardio scores when you work out based on your heart rate and VO2 data, but you can’t track specific exercises. Although disappointing, this is standard with smart rings. In addition, considering I was taking the ring off at the gym anyway to avoid it becoming scratched, I didn’t think I missed out. I'd need a separate device for that.
Data collection is mostly accurate and in keeping with other trackers, such as the Ultrahuman Ring Air and the Apple Watch that I wear all the time. This is good to know, since I have been under the impression that smart rings need to be worn quite specifically and don’t collect data accurately; but the Circular Ring Slim did a decent job.
The one area where it struggled at times was sleep. Over the majority of nights, the data the smart ring collected was accurate and useful. However, any disturbances in the night appeared to throw it off. For example, there have been occasions where I’ve woken up at night around 4am for 15-20 minutes. I usually have some water, read, and ease myself back to sleep, regularly catching at least another couple of hours or so of sleep. However, several times, the Circular Ring Slim assumed I was up for the rest of the day from 4am and didn’t track me returning to sleep.
Several big issues affected the daily wear and use of the Circular Ring Slim, too. The one that let down the device, and me, most was battery life. Note here that the ring features two battery modes. There’s Eco, which offers infrequent heart rate tracking but no sleep insights. You’ll get just under five days from the Ring Slim in that mode before it will need a top up. Then there’s Performance mode, which tracks everything, including sleep stages. In this mode, the ring lasted only two days before needing a charge.
You might believe that having a choice of two modes is desirable; however, I’m not convinced that anyone who purchases a smart ring for $264 would ever be happy with it running the bare minimum of features. If you are someone who might be satisfied with that, I suggest opting for a cheaper fitness tracker instead. Also consider that rival models are offering significantly longer on a single charge, with the Ultrahuman Ring Air lasting six days and the Oura Ring (Generation 3) lasting up to 7 days.
In my own experience, in Eco I spent a lot of time worrying about the battery life and when exactly I’d charge the ring, which affected my overall experience. Often I’d choose to charge it overnight, but this meant missing out on collecting sleep data. While charging every two days might be standard practice for a tracker with a bright screen like the Apple Watch, for example, I’d want more from a smart ring.
Setting up the ring was relatively easy, but I did experience issues with syncing during testing. This tended to happen in the morning, especially if the battery was low; I experienced two instances where my sleep data didn’t sync and failed to do so for the rest of the day.
The Circular Ring Slim’s app presents you with all of the data the ring collects in circles at the top of the home screen, providing quick access to the stats you might want to see the most, such as sleep analysis and energy analysis – a little like the “readiness” score you get from other trackers. I like how these circles work, but I encountered lots of other issues with the app that made it frustrating to use. It presents a cluttered design, navigation can be clunky, and in some areas the convoluted copy requires an overhaul.
For example, I hit a step goal one day, and the app told me I had won coins. That was accompanied by the question: “What could this possibly mean?” – which already sounds a little strange. Add to this that there was no option to click through nor actually an explanation of what it does mean. On having a decent night’s sleep, the app reported the experience as “correct” – which, again, is a strange way to describe sleep. And I’ve already mentioned the super wordy, long questions asked during the setup process.
These are just a few examples of many that made the app experience poor; hardly the premium wellness experience to compete with the likes of Oura. In fact, on a personal note it would probably dissuade me from looking at my data. Luckily, this could be a relatively easy fix for Circular, with the brand simply paying more attention to understanding the journey users will take through the app and a copy overhaul.

How I tested
I tested the Circular Ring Slim for six weeks with an iPhone 14 Pro. I wore it while walking, working out at the gym, working remotely from a library, and then travelling to Italy for 10 days. This gave me a great opportunity to put it to the test outside my regular routine.
I’ve also been reviewing tech for more than 12 years, with a particular focus on wearable and fitness tech.
