Sleep Number ComfortFit Pillow: two-minute review

I love to sleep, and I also love to sleep comfortably. As a result, I also love to test bed pillows, since they play a significant role in determining how comfortably I’ll sleep. And I could tell at first glance that I was going to enjoy testing the Sleep Number ComfortFit Pillows. Some pillows arrive compressed, and when they’re expanding, it’s a wait-and-see process. Will the pillows be flat, or will they be nice and fluffy?

Since the Sleep Number ComfortFit Pillows aren’t compressed, I knew as soon as I opened the shipping box that they were going to be a pleasure to review. As I unzipped the individually packaged pillows from their stylish fabric bags (with handles, no less), I knew this level of detail in packaging would probably extend to a high level of detail in making the pillows as well.

And I was not disappointed. The pillows were thick and plush (my favorite two adjectives when describing something that I’m going to lay my head on). The fill is made of memory foam and also down alternative fibers for a cushy experience that’s still firm enough to provide support. And since they’re also available in two other shapes, the pillows can work well for side, back, and stomach sleepers.

I tested a pair of the Sleep Number ComfortFit Pillows for over two weeks to see how they compare to the rest of the best pillows on the market. And if you’re looking for ways to really boost your sleep comfort further, take a look at our guide to this year's best mattresses for all budgets.

Sleep Number ComfortFit Pillow review: price & value for money

• Premium pillow, premium priced
• 100-night trial period, 1 year warranty
• Currently buy one, get one 50% off

At $99.99, the classic Sleep Number ComfortFit Pillow in the standard size is considered a higher-end pillow – although there are competitors with pillows that cost significantly more. However, it’s not a cheap or mid-range pillow. Having tested dozens of pillows, I consider the price to be fair, considering the quality design and materials – in fact, I think it’s a good value for what you get.

The classic king size pillow is $119.00. Also, the various shapes have different prices as well. The standard curved pillow is $119.99, and $139.99 for a king. And the ultimate shape pillow, which has three removable inserts so you can find your perfect fit, is $139.99/standard, $159.99/king.

At the time of publication, the pillow was being sold (in every size and shape) as buy one, get one 50% off.

A relatively-comparable alternative is the GhostPillow Faux Down Pillow, which is regularly priced at $139 but on sale for $70. It has a microfiber gel fill, and a breathable cover made of 100% cotton. It’s a fluffy, squeezable pillow like the Sleep Number ComfortFit Pillow, and while it’s on sale, can save you quite a few bucks. However, it’s not available in different shapes and sizes

If you’d prefer a foam pillow and/or you tend to sleep hot, the Nolah Cooling Foam Pillow has cooling features, as well as a stylish design that allows it to be used without an additional pillowcase. In addition, the cover can be washed. It’s supportive, but not as squishy soft as the Sleep Number ComfortFit Pillow.

Sleep Number provides free shipping for the pillow. There’s also a 100-night trial, and a 1-year warranty. In comparison, GhostPIllow provides a 101-night trial period and a 5 year warranty, and Nolah provides a 30 day trial period and a 2 year warranty.

Sleep Number ComfortFit Pillow review: design and materials

• Memory foam and down alternative fibers
• 3 shape choices for side, back, and stomach sleepers
• Breathable Lyocell blend cover

I chose the classic shape, which is recommended for stomach or back sleepers. However, there’s also an option to get the curved pillow, which provides enhanced support and works best for side or back sleepers (I’m testing the curved pillows in a future review). In addition, the ultimate shape has three removable inserts, which can be used for any type of sleeper since the inserts can be taken out (or left in) to customize the pillow. 

The Sleep Number ComfortFit Pillow includes a blend of memory foam pieces and down alternative fibers. The memory foam pieces are moldable, so they fit the shape of my head and neck, and also bounce back when I move your head. The down alternative fibers are designed to imitate the luxurious feel of down. However, alternative or faux down tends to cost less. It’s also a great choice for people who may be allergic to down.

Delivery was uneventful, and set-up was quick and easy, since the pillows were not compressed, so they didn’t need time to expand, and I didn’t have to deal with any potential off-gassing. However, I do want to note that Sleep Number takes presentation very seriously. I was impressed with the individual cloth bags inside of the delivery box. These zippered bags added an extra layer of hygienic protection, and were convenient when storing or transporting the pillows.

Sleep Number ComfortFit Pillow review: care and allergies

The pillows cannot be machine washed (only the ultimate shape pillow has a removable cover that can be machine washed). Spot cleaning is recommended for the classic and curved shapes.

The down alternative material is quite suited for someone with allergies, since it’s not actual down – which serves as an allergen for some people. In fact, the pillows are actually hypoallergenic.

The pillow contains CertiPUR-US certified foam, which means that it was made without formaldehyde, ozone depleters, phthalates, mercury, lead and other heavy metals, and meets the low VOC emissions standard for indoor air. It’s also screened to be free for fire retardants and other chemicals that have been classified as mutagens or reproductive toxins, or carcinogens.

Sleep Number ComfortFit Pillow review: comfort & support

• Thick and plush, but not too plush
• Best for side or back sleepers
• Bounces back and does not need refluffing

For over two weeks, I slept on a pair of Sleep Number ComfortFit Pillows to see how comfortable and supportive they were. The pillows were very plush, akin to sleeping on a cloud. As a result of the memory foam, the pillows molded to the shape of my head and neck, and when I changed positions, they quickly bounced back and proceeded to cradle me in my next position. And since the pillows contains down alternative, they felt luxurious, and were breathable.

The pillows are a mid-loft version that’s not too high and not too low. In side and back positions, it supported me well. However, it may have been too high to provide consistent support for someone who always sleeps on their side. (The ultimate shape would do a better job for side sleepers).

I did not need to re-plump the pillows, due to the combination of fill contents in it. This pillow would be great for the average customer who sleeps on their back or side. It may be too high for petite sleepers. 

Sleep Number ComfortFit Pillow review: temperature regulation

The Sleep Number ComfortFit Pillows have a breathable Lyocell blend cover. Since neither the fill nor the cover trapped heat, the pillows didn’t get hot while sleeping – even though, as you can see from the photos, I was underneath plenty of bedding.

The pillows didn’t necessarily feel cool to the touch, but I was satisfied that they were not making me hot either, since they were breathable, which allowed any heat to escape. I tested the pillows during the fall season, which in Birmingham, AL is comfortable enough to turn off the HVAC.

Sleep Number ComfortFit Pillow review: specs

Should you buy the Sleep Number ComfortFit Pillow?

Buy it if...

✅ You want the best of both worlds: The pillow contains both memory foam and alternative down for a unique experience. It’s luxurious and smooth, while also being squishy, soft and supportive.

✅ You prefer down alternative to down: If you’re allergic to down, you’ll appreciate that the pillow mimics down, but it’s hypoallergenic, so it doesn’t have any of the allergens that may cause you discomfort. Also, it doesn’t have any feathers to protrude and poke you.

✅ You want a luxurious feel: The high-end pillows aren’t as expensive as many other types of high-end pillows, so this is an opportunity to upgrade your existing pillows without breaking the bank. You can get a pair of pillows that you won’t have to replace every year.

Don't buy it if...

❌ You’re strictly a side sleeper: The pillow works best for back sleepers and stomach sleepers. If you always sleep on your side, you might not find the height to provide the right combination of support and comfort. (However, the curved shape is designed for side or back sleepers and the ultimate shape is adjustable, so it can be customized for side sleepers as well.)

❌ You like to adjust the fill: If you get the classic shape, you won’t be able to unzip the cover and remove or add fill. So, if you don’t think the amount of fill is suitable for your needs, keep in mind that you’re stuck with that loft. The ultimate shape pillow is adjustable, but if you want another option try the Layla Kapok Pillow.

❌ You like to wash your pillows and covers: You can’t wash the pillow, and you can’t even unzip the cover and wash it (although I used to toss the pillows in the dryer on the sanitize setting and it didn’t appear to affect performance). The cover is hypoallergenic if that helps, but if you want a fully washable option the GhostPillow Faux Down Pillow could be a good alternative.

How I tested the Sleep Number ComfortFit Pillow

I slept on the Sleep Number ComfortFit Pillows for over two weeks, testing for performance, comfort, and support. These tests were conducted during the fall season. Since I tend to sleep hot – but I love all of the stylish fall and winter bedding – I slept with the HVAC off to avoid getting overly hot in my mild climate.

Aura smart sleep mask: two-minute review

The Aura smart sleep mask uses light and sound to transform a basic eye mask into a mindful, immersive experience. I tried sleeping with the Aura mask for a week, and as someone uses an eye mask every night, I was excited to see whether a smart upgrade really could improve my rest.

Crafted with integrated speakers and an in-built ‘glow’ light, the sleep mask connects to the Aura app to provide a customizable sleep experience. You can mix and match ASMR sounds, guided meditations, and nature soundscapes to craft a meditative wind-down routine, while in the morning, the sunrise function gently wakes you up with light and sound.

The basic design of the Aura mask is excellent. The sculpted interior ‘Hug’ cushion keeps the pressure off your face and blocks light completely, while the anti-slip straps hold the mask in place even over restless nights. Back and side sleepers should be able to get comfortable, but stomach sleepers are likely to find the mask presses into the face.

Thanks to the blackout effect and calming sounds, it’s easy to get immersed in the Aura experience. If you’re struggling to find a mindful headspace before bed, the Aura separates you from the outside world while encouraging relaxation. And with a lightweight build and easy charging method, you can take the Aura’s calming techniques with you when you travel.

However, it’s expensive for a sleep mask, and I’m not sure the features entirely justify the price. There are some issues with the user experience and the app is basic, which seems at odds with the price tag. The Aura is a product like no other, and if you want a more mindful bedtime routine (especially on the go) it might be worth the money. But if it’s just better sleep you’re after, a basic eye mask is probably the better starting place. 

I tested the Aura smart sleep mask in Midnight Black, which is available for pre-order and will be released 14th March. The Aura smart sleep mask original was launched in November 2023. and is available for purchase from Aura.

• Buy the Aura Smart Sleep Mask in Midnight Black from Aura

Aura smart sleep mask: price

• MSRP US$358 / £285 / €339.95, often discounted to US$229 / £182 / €218.95
• Aura app is free to use
• 1 year warranty for the mask, Hug insert has a 3 month warranty

The Aura smart sleep mask has an MSRP of $329, although it’s regularly discounted, so don’t expect to pay full price. Aura has previously discounted the original sleep mask by up to 40 per cent, taking it down to $199.

Even at a discount, this is an expensive buy, especially considering a basic sleep mask is only a few dollars. However, the Aura is pretty unique. While blackout masks, sleep masks with integrated speakers, and sunrise alarm clocks exist separately, as far as I can tell the Aura is the only one that combines all three.

Aura offers a one year warranty for the mask, while the interior insert has a three month warranty. The app is free to download and doesn’t require a subscription to use it. This gives you access to the full range of features at no extra cost – a welcome bonus, as you can’t use the mask without the app. It’s not unusual for smart products to charge an app subscription cost on top of the original price, so I certainly appreciate that the Aura doesn’t require this. 

Is the Aura mask worth it? Thinking of it less as a sleep mask with some added features and more as a sunrise alarm clock with a speaker, a blackout design, and excellent portability, the cost is somewhat justified. There are limited uses to the Aura, but for those after improved mindfulness before bed, the mask delivers.

Aura smart sleep mask: design

• Magnetic 3D Hug insert relieves pressure at the eye area
• Velcro strap for a secure fit
• USB-C charger included

The Aura looks like a bigger, bulkier version of a standard sleep mask, but the simple design hides everything interesting happening underneath. Available in two colors – gray and black – the Aura has a sleek appeal. A few interesting colorways would be welcome, especially considering the price, but the overall look is stylish.

Inside sits a detachable 3D Hug band. This is a sculpted, cushioned band that sticks to the interior of the mask with a magnet, taking the pressure off the face while blocking all light. The outer material and the interior Hug are both soft against the skin, and the 3D effect prevents the mask from damaging the eyelashes. Straps at the back use velcro for an adjustable fit, with an anti-slip design to prevent the mask from moving around in the night. 

Hidden inside the mask is a set of ultra-slim speakers. Because the speakers aren’t set directly over the ears, there is some sound leakage – if you share a bed, your partner is likely to hear what’s coming from your mask, although not clearly. 

Sitting just in front of the eye line on the interior of the mask is a small ‘glow’ bar. This is a gentle light, but when the mask is closed, it does flood the space. It’s also not visible from the outside when wearing the mask.

Aura claims the battery lasts for seven nights of normal use, which I found accurate. However, the battery life does depend on usage – if you choose a particularly long soundscape, expect the battery to drain quicker. A light on the mask indicates when the battery is running low, and you can check battery life by connecting to the app. As the Aura charges directly via the cable, you can’t comfortably use the mask when it’s charging. 

Weighing 4.59oz (130g), this is heavier than your average sleep mask, but feels surprisingly light on the face. It’s also light and compact enough to travel with. The Aura does come with a small bag that I assume is for traveling, but it’s very hard to actually get the mask in there, so it might serve some other purpose I’m not aware of.

The interior Hug band is removable and can be machine or hand washed with mild detergent. Leave it to dry completely before reattaching to your mask. The mask itself is spot clean-only, and you should avoid getting it wet.

Aura smart sleep mask: features

• 100 per cent blackout eye mask
• Integrated speakers play customizable soundscapes
• Glow light provides a sunrise alarm effect

At a basic level, the Aura is a 100 per cent blackout sleep mask. Thanks to the thick fabric and molded shape, no light can get in from any side, leaving you in total darkness. While it does rely slightly on the contours of your face roughly matching the Hug insert, for most people, the Aura should block essentially all light.

But this is the simplest function of the Aura. The Aura is a smart sleep mask, able to connect via Bluetooth to the Aura app to play sound, light, and act as an alarm. As well as white noise for sleep, the Aura offers guided meditations, nature soundscapes, and ASMR, which you can schedule and customize depending on whether you’re waking up, going to sleep, napping, or meditating. Because it uses Bluetooth, you can also play your own music through the Aura…  although I wouldn’t recommend it, as I’ll discuss in the performance section below.

As well as soundscapes, the Aura also contains a sunrise light. This gentle glow bar is located on the interior of the mask, and it pulses along with certain meditations and noises. It also acts as a sunrise alarm clock, with the light gradually increasing at your chosen wake-up time, for a gentle start to the morning. 

The Aura app has its own set of features, but it’s primarily used to control the Aura. While there’s a small sleep diary, its functions are minimal, and it primarily tracks your chosen wake-up and sleep times. The app also sends occasional notifications, indicating it’s time to nap, get ready for bed. These need a bit of fine tuning – I received a wake-up notification several minutes after the alarm had gone off, when I’d already disconnected the Aura and closed the app, for instance. 

Aura smart sleep mask: performance

• Comfortable fit that stays in place during the night
• Immersive experience from blackout design and speakers
• App is basic and not particularly user-friendly

First, let’s talk about the Aura as a sleep mask. It’s soft against the face, with the velcro strap allowing you to create a close and secure fit. The inner Hug cushion is sculpted to the eye area and even with the straps as tight as they would go, it’s comfortable and won’t press against your eyes. An anti-slip coating prevents the Aura from moving during the night if, like me, you toss and turn.

This contoured fit prevents light from leaking in around the edges of the mask, creating a 100 per cent blackout effect. With the mask on, it’s honestly hard to tell if it’s day or night. As someone who struggles to sleep with even small amounts of light in the room, this is a real bonus. But this close fit did come with a slight downside – it could get warm.

Using the Aura app, I designed a series of soundscapes for meditation and to help me fall asleep. With white noise, meditation tracks, ASMR, and nature sounds to choose from, there’s enough variety to suit the majority of sleepers. It was fun to craft these soundscapes, and while I normally kept my sessions under the 30 minute mark, you could push it much longer if you wanted sounds to last for most of the night.

The in-built speakers gave the Aura something of a surround sound effect which, combined with the total blackout, made for a deeply immersive experience. I often struggle to concentrate during meditation – the urge to peek is just too strong. With the Aura, it was much easier to get into the serene headspace and stay there. Plus, because the mask was already on my face and the alarm was set, at the end of the soundscape, I simply had to lie down and go to sleep. No disruptions to my calm mood.

That’s at the start of the night. For the morning, you can use the app to set an alarm for your chosen wake-up time. When the time comes, the ‘glow’ light will gradually illuminate, simulating a sunrise, before the sound kicks in.

The wake-up is impressively effective, with the light and sound coming together to create the feeling of a natural beginning to the morning. I did find it a little slow at waking me up, but that’s by design – this isn’t the jarring alert of a standard alarm. However, I always set the alarm to start a few minutes before I actually wanted to wake up, so it had time to work. 

Aura claims the mask is side sleeper-friendly, and I found this largely accurate. Sometimes it took a minute of adjustment to get my head, the mask, and the pillow just right, but after that, the mask stayed comfortably in place. 

I also found it much easier to get comfortable when I switched my pillow. I usually sleep on a medium-firm, all-foam pillow. The foam gently contours to your head, but it doesn’t have a huge amount of give (read my Levitex pillow review to learn exactly what it’s like). When I used a feather pillow with more yield, there was less pressure from the mask overall. If you’re interested in the Aura, consider what’s the best pillow to suit this smart mask. 

Back sleepers shouldn’t have any issues with the mask, however, it’s not recommended for stomach sleepers. The sides of the mask press into the face, so unless you twist your neck all the way around, it's pretty uncomfortable in this position. 

Connecting the Aura to the app was easy, although I question why the power button is in the middle of the face, rather than along the top bar with the rest of the buttons. With the mask on, it’s hard to locate just where the button is. I spent the first part of any mindfulness session randomly pressing my face and hoping for the best. It’s easier to find when you don’t have the mask on, but then it’s a rush to get comfortable before your soundscape starts.

As it uses a Bluetooth connection, you can also use the Aura to listen to your own music or meditations. However, I don’t recommend it. While the speakers are fine for meditations and white noise, there are some obvious issues with sound quality when listening to music. It’s definitely not good enough to replace a set of headphones. 

The app itself has room for development. There’s a sleep diary with space to record my wake up time and sleep time, plus an emotion and a gratitude prompt. There's no real space to track your bedtime routine, and using the sleep diary isn’t hugely intuitive. Overall, the app could be more user-friendly – the design seems to prioritize minimalism over navigation, which did not put me in a very mindful place. However, I do appreciate that this is a free app, and as the Aura is a relatively new product, there’s plenty of time for development in this area.

The mask isn’t the most user-friendly design and it has limited uses. For example, while the immersive experience is great for meditation, the blackout effect means it’s no good during yoga. 

But used before bed, the Aura has some real benefits. The combination of blackout and sunrise light allows you to really tap into your circadian rhythms. At night, I could drift off in darkness, while in the morning, natural-seeming light helped gently wake me up. For meditation, the Aura can improve concentration for anyone with wandering thoughts, and I could see the same benefit if you’re struggling to sleep from stress or anxiety. By balancing mindfulness with real-world features, the Aura can be a helpful addition to the pre-bed routine.

Aura smart sleep mask: should I buy it?

Buy it if...

✅ You’re sensitive to light: Sleep masks are excellent at blocking light in the evening, making it easier to fall asleep. However, that same blackout effect can be problematic in the morning, when you need light to wake you up. The Aura navigates this issue by incorporating light into the mask itself, waking you up with a natural seeming daylight.

✅ You struggle to concentrate during meditation: As someone who gets distracted easily during meditation, the Aura sleep mask helped me add some mindfulness to my bedtime. Surrounded by sound and with a total blackout, you’re pretty much forced to concentrate. And with the velcro straps keeping the mask close to your face, there’s no temptation to peek. 

✅ You travel frequently: A lightweight build makes the Aura easy to travel with, while the total blackout effect and immersive soundscapes can help you relax even in unfamiliar, noisy, and bright environments. And thanks to the glow effect alarm, early morning flights might feel less disruptive (there’s even a pre-flight anxiety meditation).

Don't buy it if...

❌ You’re on a tight budget: You could buy a lifetime's supply of standard sleep masks for the same price as the Aura. Of course, you won’t get the light and sound functions that make this smart mask standout, but if you just want a darker night, it’s not worth the money. And if only one of the smart features appeals to you (for example. Integrated speakers) there are cheaper options available. 

❌ You sleep on your stomach: The sculpted face of the Aura sleep mask presses into the face in most stomach sleeping positions, requiring multiple adjustments to get comfortable. Whether you spend the entire night on your front or you're a combination sleeper who moves around, there are some sleep positions that just don’t work with the Aura.

❌ You want all your sleep tracking in one place: The Aura app is free but basic and the sleep diary is bare bones. While I didn’t expect the app to track my sleep, I would have appreciated a little more functionality. Overall, it’s not the most intuitive design to use, and it seems like a missed opportunity. A functioning sleep diary plus more space to record your thoughts and mood would have really added to the experience.

Aura smart sleep mask: How I tested

I tested the Aura smart sleep mask for a week, using it both before bed as part of my wind-down routine and in bed to help me sleep and wake me up in the morning. I tested during a mild spring in Wales, in a room without blackout curtains. I also used the Aura around other people, to see how much sound traveled.

Graphite Memory Foam Mattress Topper: two-minute review

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.

Saatva Graphite Memory Foam Mattress Topper review: design & materials

• 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.)

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. 

The Graphite Memory Foam option is one of a number of different toppers available at Saatva – for a run-down of the rest of the range, and who they might suit, head to TechRadar's article exploring 'Which Saatva topper should I buy?'

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.

• Twin: MSRP $325
• Twin XL: MSRP $325
• Full: MSRP $405
• Queen: MSRP $445
• King: MSRP $565
• Split King: MSRP $650
• Cal King: MSRP $565

While Saatva mattress sales and deals happen pretty much constantly, it's very rare that the toppers will be included. 

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) . 

Saatva Graphite Memory Foam Mattress Topper review: comfort & performance

• 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.

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.

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.”

Saatva Graphite Memory Foam Mattress Topper review: customer experience

• Free delivery but $99 fee for returns 
• 180-night trial and 1-year limited warranty
• 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.

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.

Saatva Graphite Memory Foam Mattress Topper review: specs

Should you buy the Saatva Graphite Memory Foam Mattress Topper?

Buy it if...

✅ 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.

Emma Premium topper: Two-minute review

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). 

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.

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. 

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.

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. 

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.
