KYY X90E Portable Monitor: 30-second review

KYY is a Chinese hardware maker specialising in portable displays, and the X90E is one of its latest releases.

Described by the makers as a ‘triple laptop screen extender’, more accurately, this is two monitors in a single package, designed to provide three times the normal screen space when used in conjunction with the monitor that the laptop already has.

Its hinged structure places a 15.6-inch 1080p display to the left and the right of the laptop, and connects via a single USB cable.

It can be configured to mirror the contents, so others can see your laptop display from different viewpoints, or provide an extended desktop.

Power can be sourced directly from the laptop, or for extended use, a small USB-C power supply is included.

The obvious limitation of this platform is that it assumes the laptop has USB-C with an ALT-DP capability or Thunderbolt 3 or 4. And, according to KYY, its designed exclusively for Windows PCs, and doesn’t work with Apple MacBook hardware.

At a little over $300 from the makers, and weighing 2.2kg, any purchaser needs to be convinced that the price and the additional carry are worth it for their productivity.

Despite a few limitations at this price point, it’s an obvious candidate for one of the best portable monitors on a budget that we’ve reviewed.

KYY X90E Portable Monitor: Price and availability

• How much does it cost? $240/£230
• When is it out? It available now
• Where can you get it? Direct from KYY or via online retailers like Amazon

As with previous KYY products, buying directly from the maker isn’t the cheapest way to get the K3 portable monitor. It's selling for $309.99 direct from KYY.

On Amazon.com, it can be found for a standard price of $239.99 - a 20% discount on its official $299.99 list price.

However, on Amazon.co.uk, the same hardware is £229.99, making it slightly more costly to those in the UK. KYY doesn’t sell on the French or German versions of Amazon, but it should be possible to find it in Europe from another online reseller.

Those looking for this hardware should be aware that KYY also makes the X90A and X90D models with different specifications, so make sure you have the X90E variant before clicking the 'buy' button.

Moving away from the KYY brand, there is a collection of remarkably similar products from other Chinese display makers, and some are more expensive, and others slightly cheaper.

Those willing to use 14-inch displays instead of the 15.6-inch displays the X90E offers can be under $200, and ones with three extra displays (making four in total) can be nearer $450.

At the Amazon.com price, this is not a major investment, even if it’s only used sparingly, placing the KYY X90E in the affordable category.

KYY X90E Portable Monitor: Design

• Structural integrity
• Various display arrangements
• Single cable connectivity

Out of the box, my first impressions of the X90E were positive. It’s constructed like Soviet-era infrastructure, with a metal skin on all non-display surfaces and two remarkably robust hinges linking the two monitors to a central support plate and foot.

The only downside of the rugged construction is that at 2.2kg, this isn’t a minor item to include in a laptop bag, and you will need one made for a 17-inch laptop to fit it.

When it’s unfolded, the width of the whole unit is a whopping 115cm, although you can make it slightly narrower by adjusting the hinges.

The standard orientation is to place the laptop in the middle and have an extra display on either side, but there are various other options, including rotating them back to provide left and right presentation screens, and also folding one screen away.

You can also use that one screen mode in portrait mode, if you like to mix your orientations.

One curiosity about this solution is that instead of there being one OSD and menu controls, each monitor has its own. I can’t seriously think of a scenario where you would configure one screen to have different brightness, contrast or colour temperature than the other, but this system has that capability.

On the subject of OSD menus, these ones don’t have a large amount of features, and the way they are navigated with buttons is painful. What I fail to understand is that these menus look unchanged from the first ones that appeared on tube monitors twenty-five years ago, same horrible fonts, same insipid colours. The maker's logic appears to be that people will only use it once, so there is little point in making it any better.

In this instance, a menu option to ‘copy to other screen’ might have been a smart choice, but clearly, the menu is something that comes with the display panels, and they’re gloriously unaware of each other.

A feature that I liked much more was that both these displays can be connected using a single USB-C cable to the laptop. That one cable supports ALT-DP to send data to both screens, and also power. The downside of having the one-cable solution is that the screen on a laptop is one of the biggest power consumers, and having three could whittle the battery capacity down rather rapidly.

If you have multiple USB-C ports, you could power the laptop, which might have enough power to drive the external monitors and recharge the battery, or you can use the included 15W PSU to power the monitors directly.

There are only two USB-C inputs on the X90E, one is for connecting and the other is for power, so it’s not possible to give one screen each to two laptops, sadly.

It’s also not on the menu for any laptop that hasn’t got USB-C (or Thunderbolt) or USB-C that supports video output, because there is no HDMI input. While this solution using USB-C is plug and play, requiring no drivers to function, to achieve those standards its exclusively for Windows PCs (7,8.1,10 and 11), and won’t work with Apple MacBook systems.

Overall, the design of the X90E is focused on a specific customer profile who uses a modern Windows laptop with a display between 14-inch and 17-inch. And, while that might seem a little niche, from a percentage viewpoint, it’s a reasonable price for those who might want more screens added to their mobile systems.

KYY X90E Portable Monitor: Performance

• Better than 300 nits
• 82% sRGB

When comparing these displays, we need to be mindful that these are inexpensive IPS technology panels, and therefore, they can’t hold a candle to OLED or MicroLED technology in terms of contrast and colour representation.

That said, the panels on the X90E were significantly better than those on the KYY K3 I previously tested, suggesting that this maker has developed improved designs.

I’m going to assume that the makers quoted 85% NTSC colour gamut is a misunderstanding, because in my tests, that number was closer to 61%. I suspect it got mixed up with the sRGB, as that’s much closer to 85%.

I say that because while the contrast isn’t the 1200:1 that KYY predicts, the brightness of these panels is almost exactly what they claim.

What information isn’t presented here is the uniformity of luminosity, which isn’t wonderful. The rear illumination of this panel is in the middle, with each of the corners being around 15% less illuminated at 100% brightness.

One curiosity I noticed was that the default White Point on these displays is 7600, not the typical 6500. The OSD doesn’t offer specific temperatures, only ‘cool’, ‘warm’ and ‘user’ definable via R, G and B settings.

Looking at this panel overall, it has decent contrast, gamut and tone response, excellent colour accuracy and uniformity, but suffers from the aforementioned luminance uniformity.

Had the backlighting been more diffuse, this might have been a great result.

I’d summarise the X90E as better than anticipated, but hardly something that those working professionally with colour might gravitate to. But for office work and presentation, in an office with blinds, it's definitely a workable option.

• Performance: 4 / 5

KYY X90E Portable Monitor: Final verdict

I recall being shocked by how usable the KYY K3 was, but the X90E is an even better solution and an implausibly low price. Yes, it’s on the heavy side, and it won’t work with anything other than a Windows laptop with USB-C or Thunderbolt, but it's hard to argue with its value proposition.

An HDMI input to allow another system to share the screens would have been a nice option, or to allow both the USB-C ports to act as inputs. But that these aren’t included, along with speakers at this price point, isn’t a huge surprise.

If you need to triple your screen space and don’t mind another 2.2kg of luggage, then the KYY X90E might be the right choice for you.

For more options, we've reviewed the best monitors for a dual-screen set-up.

The Carbon 2 Combo follows hot on the heels of the Centauri Carbon launched last year, and is aimed as a family friendly multicolour filament machine. While we expected the multicolour filament system for the Carbon, this is still in development and is expected later in the year.

The Centauri Carbon 2 Combo is not only a worthy addition to the original Centauri but also offers a slightly different take on the multifilament design, although it doesn’t stray too far away, offering four-filament printing at an extremely budget-friendly price.

When the Centauri Carbon launched, it stood alone as a machine that was exceptionally cheap for what was on offer, and while the Centauri Carbon 2 Combo is still an engineering machine that comes in at a relatively low price, it now has competition from most of the other main manufacturers, so it doesn’t stand out to the same degree.

That said, the Carbon 2 Combo is a solid machine with its sturdy build, and unusually for a multifilament machine at this price, an almost completely enclosed design, although the filaments are still left exposed on the outside of the machine before being passed through the Elegoo CANVAS system into the single nozzle head inside.

Having tested the original Carbon and been impressed, this new iteration is certainly exciting, even more so when the quality of the machine is revealed as it’s removed from the box.

Elegoo Centauri Carbon 2 Combo: Price and availability

The Elegoo Centauri Carbon 2 Combo is available now and can be purchased directly through the Elegoo US website for $449, and via the Elegoo UK website for £399.

• Value: 5 / 5

Elegoo Centauri Carbon 2: Design

Once again, the Centauri Carbon 2 Combo is a solid and slightly weighty machine considering its small size, coming in at 19.69 x 18.90 x 29.25 inches and weighing 42.66 lb.

While the machine itself does look and feel quite small, once you've put the Perspex top in place to make it completely enclosed and popped the four reels onto the side of the machine, it does start to add to the size and bulk of the unit. But it’s still far smaller than many of the larger fully enclosed systems that I’ve reviewed in the last year.

Again, the styling is nicely product-designed with the main framework of the machine being made out of metal, which gives it that sturdiness and weight, essential for COREXY. Likewise, the four filament reel holders on the side slot on brackets are secured through bolting onto the body, and again, they hold firm and tight and have an exceptionally high-quality feel.

The one oddity is the box that sits on top of the machine. It's very much like the protective covers that you use on resin printers and simply slots over the top of the feeder tubes from the CANVAS unit that's bolted to the top right of the machine.

Compared with the advanced multifilament boxes with filament drying, this all seems just a little bit more basic, but then again, this is a cheaper multifilament machine than some others, and when you compare it against the likes of the newly released Anycubic Kobra X, it does feel like a level up.

That, and the fact that alongside the use of metal for the main frame, it features a glass door and otherwise very clean industrial styling with very Elegoo futuristic graphics, that do give it an enthusiast rather than professional look.

One of the major features that stands out is the new integrated CANVAS system, which needs to be installed when the machine arrives. Essentially, there’s a single bracket that screws into the top of the machine, and the CANVAS is then mounted onto the bracket. Once it’s attached and that Perspex top is put in place, it all feels nice and secure, if not as product-designed as the rest of the machine.

When it comes to control, Elegoo has really worked at slicing software, and it's pretty much in line with the rest of the industry when it comes to functionality and ease of use. But what really stands out is the front-mounted touchscreen, which again is nice and large, clear and easy to navigate. And with RFID filament reels, it’s extremely easy to use, recognising the filaments that you’ve installed, so you don’t need to go in and manually program them.

Elegoo Centauri Carbon 2: Features

One of the big new features of the Centauri Carbon 2 is, of course, the fact that you can now do multicolour 3D printing. It does this by means of the CANVAS system, which is bolted to the side of the machine with four filaments mounted on the side feeding through into a single nozzle printhead. It looks a little bit different from most other multicoloured systems on the market, but functions much the same.

Like the original Centauri Carbon, this machine is once again aimed at beginners, hobbyists and anyone who's looking for a relatively small, multifilament-ready machine that can handle engineering materials but is slightly limited for space, and, of course, budget.

What surprised us about the original Centauri was that its price did not reflect its quality. It was an absolutely superb machine for not a great deal of money, and once again, the quality of the Centauri Carbon 2 is of exceptionally high quality. Even against other relatively budget multifilament machines, it is in a class of quality of its own.

The biggest innovation of this new machine is the new CANVAS system. This is essentially a box that sits on top of the machine and feeds the filaments mounted on the side of the machine into the Tool head inside. In order to make the machine fully enclosed, or at least the print area, that Perspex box sits on top, essentially making it almost airtight, giving a far more controlled printing environment than that of the open-style printers that are much more common at this end of the market.

One of the aspects that I like about this machine is the design of the CANVAS system. From the outset it’s just easy to use and as soon as you place the filament into the feeder tube, it’s grabbed and pulled through the system. It doesn’t involve you having to manually feed filament through. Once it’s in, you know it's inserted properly, and the machine essentially handles the rest of the process for you.

Another feature now becoming more common across all 3D printers is the RFID-based filament detection. If you're using the Elegoo RFID filament reels, you can essentially just tap these onto the machine over the RFID reader, and the filament will be recognised before it's used in the system. This means you can't accidentally use ABS to print with a PLA profile.

As with many other manufacturers, Elegoo has its 3D print community platform, which enables the easy sharing of 3D print models and the Elegoo community. This also means that you can instantly download files from the NexaPrint platform directly to the printer without needing to do your own modelling or download from other systems, which just helps to streamline the process for those just getting into 3D printing.

Once again, the machine uses the CoreXY mechanism, which makes it incredibly fast compared with the old Cartesian-style machines. And whilst it still makes a noise when printing, it is relatively low, which makes it a good option if you are using this in the home or in a small office.

As we saw in the Centauri Carbon and in most 3D printers these days, there is a 5-inch touchscreen with an intuitive interface that makes it easy to navigate both the prints and the printer settings.

When it comes to nozzle temperature, the machine is capable of going up to 350°C. This is enough for most engineering materials and elevates this above most other entry-level machines. The enclosed print environment also helps with more complex materials such as ABS and nylon, which require a more stable printing environment to avoid warping and other print defects.

As we’ve now seen across the board from other 3D print manufacturers, there are all of the new features that come with these CoreXY machines that we’ve come to expect, including fast printing, smart auto-levelling, temperature control and, most importantly, consistency across the prints regardless of the material used.

Elegoo Centauri Carbon 2: Performance

I started off with the Centauri Carbon 2 by just running through a series of pre-installed models and was impressed instantly with the quality of model it was capable of producing. Checking out the layer quality of the single filament prints showed just how high-quality a printer this is, which is even more impressive considering the price.

Having run through the single filament prints in a relatively short time, I moved on to the multifilament print. Here, they’ve only included a couple to get started with, one of which is the Elegoo logo on a small badge. Again, this printed in a relatively quick time and, like when used for just a single filament print, the machine started its purging process out of the back, with a small pile of filament building up as each colour was swapped through the CANVAS system to create the print.

While the conditions at the moment are exceptionally cold, around 0°C outside and around 19°C in the workshop, that temperature unfortunately does drop, and the humidity is slightly higher due to the time of year, with the constant rain in the UK. This has meant that, through the test, initially I had the reels mounted on the outside of the machine in the workshop, and some very fine filament hair was appearing on the multicoloured print.

I then moved the machine into the office and replaced the filament, at which point the filament hair disappeared, and the print was clean. This is worth considering, as unlike some of the more expensive multifilament printers that keep the filament in a dry box so it stays in top condition, here, while the machine itself is fully enclosed, the filaments are left exposed on the outside. So, if you are in a workshop or studio where temperatures and humidity can drop and build, this is something to be aware of.

Another point to note is that the filament holders on the side hold card reels well and securely, although with some plastic reels, I had a couple of occasions where the Elegoo PLA reel slipped off the holder. I ended up putting a small rubber sticker onto one of the sides of the holder, which just helped to grip the reel's inner a little more robustly.

As the prints came off the print bed, the printer didn’t fail to impress. The multifilament printing quality is exceptionally good, with clean lines, and when I did a print with white and purple, there was very little contamination between those two filaments, which is an issue that I’m increasingly seeing with some of the cheaper multifilament 3D printers.

When it came to some of the more standard 3D printing traits, the quality of the print was exceptionally good, with the dimensional accuracy being well handled, no doubt helped by that enclosed print environment. While there are some small issues, especially with dimensional accuracy, the overall quality is more than enough for most home and small business users, even if you want to make functional parts.

While standard single and multiple printing is all very well and good, this is the Centauri Carbon 2, so it’s designed to work with engineering materials, not just standard PLA. Taking a look at some common filaments, I was pleased to see the Centauri Carbon 2 was once again able to print with these materials as easily as standard ones, and they seemed to feed through the CANVAS system far more reliably than I’ve found with some of the other multifilament options available. Print quality once again was exceptionally good, and dimensional accuracy really stood out, which is impressive considering the price of this machine.

If you are a small business looking to make functional parts on a budget, then the Centauri Carbon 2 really does live up to expectations.

The one issue here is that, while you can print with these advanced materials, compared with the likes of the H2D and some of the other larger machines, your print area is rather limited, but will still give you good flexibility over what it is that you're printing.

For some more advanced users, this is quite a locked-down system, with very little flexibility, especially through the Elegoo slicer, to really dive deep into the machine settings. It’s good to see that there is live printing and remote monitoring through the software, meaning that for small businesses, this is a really good and affordable option.

Elegoo Centauri Carbon 2: Final verdict

Elegoo needed to produce a near-perfect machine with the Centauri Carbon 2, as the original had really surprised the market when it arrived due to its quality and price. While there was some upset when it was announced that there would be no multifilament upgrade for the Centauri Carbon, Elegoo have gone some way to address this with a decent upgrade offer for Centauri owners to the Centauri Carbon 2.

While that still hurts a bit, because you are having to buy an all-new machine, the cost of this new model is only a little more than some other manufacturers charge for the multifilament dry boxes and there is a loyalty program from Elegoo which if you are a Centuri Carbon owner is well worth checking out.

When it comes to print quality, the detail and accuracy of the prints really do stand out, and while there are some imperfections, once again considering the level of this printer, especially when you compare it with printers of the same price from other manufacturers, this is exceptional value. Not only does it stand alongside some of the market leaders, but because it's able to handle engineering materials and has that fully enclosed environment, it is still one of the best-value 3D printers on the market.

Now Elegoo have two phenomenal 3D printers: the Centauri, which really takes the market for single filament engineering printing on a budget, and now the Centauri Carbon 2 offering multifilament printing at the same quality with a similarly sized machine. You have two affordable options for home and business that really don’t fail to impress in almost every way.

Should I buy the Elegoo Centauri Carbon 2?

I can see why Epson has sold over a 100 million EcoTanks. Being the first to bring the refillable concept to market, Epson hasn’t stopped tweaking the design so that the Epson EcoTank ET-4950 series looks like the slickest all-in-one inkjet in the shop.

I’m testing the white ET-4956 variant, but its also available in black and they both come with a feature-set to suit any small business or home-based professional. It can both duplex print and duplex scan as well as offering an improved automatic document feed (ADF) and a faster print speed than its predecessor.

The main attraction is the huge amount of inbox ink (enough to print for three years), but the asking price is rather high, so let’s see if the new model can maintain Epson’s lead in the increasingly competitive refillable 4-in-1 printer category.

Epson EcoTank ET-4950 series: Design and build

The redesign looks fresh to my eye, especially in this white livery. The folding front panel ensures the touchscreen display is always visible, while the new status light encircling the top of the ink tank cover makes it easy to see if and how your printer is responding from the far side of the office. The smooth plastic feels sturdy enough and the motorized paper output glides out smoothly every time you’re ready to print.

The paper input tray can hold an adequate 250 sheets of paper up to letter or A4-size, but it’s a pity there’s no second input tray as this means you’ll need to unload the main tray each time you want to print on different media.

The 2.4-inch touchscreen is somewhat small, but big enough to operate and quite sensitive. The cable ports are easily accessible at the left side and the fairly large 70ml ink tanks are well integrated on the other side. It’s a practical design overall and the whole thing feels well made.

Epson EcoTank ET-4950 series: Features & specifications

As the top model in Epson’s three-strong range, the ET-4950 series is a four-in-one multifunction device with print, scan, copy and fax functionality, plus plenty of extras. The ADF on top can hold 30 sheets of paper and copy both sides of each page automatically.

That’s something the previous model couldn’t do. It’s using a PrecisionCore print head with 784 inkjet nozzles to achieve a print resolution of 4,800 x 1,200 DPI. WiFi 5 with AirPrint compatibility is built in and it can print on paper up to 300g/m².

It prints quickly for an inkjet with a claimed top speed of 35ppm (pages per minute) with simplex monochrome pages or 23 in color. That’s slightly confusing as the ISO/IEC 24734 is just 18ppm, but suffice to say, that it printed a little faster than its predecessor and compares well with other inkjets in its class. The quoted 8.5-second FPOT (first page out time) is accurate and also PDQ (pretty darn quick).

The only features missing are Bluetooth, NFC, a USB Host port for printing from or scanning to a USB stick and a multi-purpose tray. The first three items I can live without, but a second paper input tray would have really improved the functionality of this printer. Perhaps Epson will include it with the next update.

Epson EcoTank ET-4950 series: Setup and operation

The printed quick-start guide is easy to follow. Just remove all the transport tape, load some paper, plug in, turn on and follow the on-display prompts.

I’d recommend downloading the Epson Smart Panel app onto your Android or iPhone first as this makes it easier to add your new printer to your wi-fi network. I’d also recommend printing out the test pages when offered to ensure all your nozzles are aligned and firing correctly.

Filling the ink reservoirs is a quick and clean process as the bottles hold the same volume of ink as the tanks — 70ml for the three coolers; 127ml for black — and each spout is shaped to fit only its corresponding tank so you can’t muddle them up.

Epson EcoTank ET-4950 series: Performance

The Epson EcoTank ET-4956 I tested put in a strong all-round performance, printing quickly and cleanly with only one paper jam where I loaded a photograph into the automatic document feed for copying. Where the manual says that it can handle paper up to 300g/m² (my photo paper was only 200g/m²) it means via the main tray and evidently not via the ADF.

That incident aside, I was pleased with my test pages, although I couldn’t honestly see any improvement over the outgoing EcoTank ET-4850 test pages. That’s unsurprising given it’s using the same heat-free inkjet technology and the same hybrid pigment and dye-based inks.

Plain pages of text print quietly in simplex mode and the paper is turned swiftly in auto duplex mode. The pigment black is applied precisely enough, but it’s not as dark as, for instance, the Canon MAXIFY GX4020, which uses a smiler hybrid ink system.

Switching to color test documents plays more to the Epson’s strengths as its dye-based C/M/Y inks are particularly bright and color documents look pleasingly vivid. It also does well with photography for the same reason.

The Epson recognizes a range of coated photo paper types and given premium glossy photo paper, my test photos really popped. This printer manages an enhanced resolution of 4,800 x 1,200, which is enough for photo printing, but dedicated photo printers, like the Canon PIXMA G3270, produce sharper images for less money.

Epson EcoTank ET-4950 series: Consumables

The Epson EcoTank ET-4950 comes with five ink bottles containing a total of 464ml of ink. That’s equivalent to around 65 regular ink cartridges and enough, Epson reckons, to print for around three years before needing to buy refills.

Epson’s bottled ink is cheap compared with cartridge ink and there’s nothing to stop you from buying third party ink, which is even cheaper. Put like that, Epson’s claim that this printer is up to 95% cheaper to run than a cartridge printer seems reasonable.

Epson EcoTank ET-4950 series: Maintenance

Epson says its heat-free printing tech means you’ll never need to replace the printhead, which is a cost incurred by plenty of other inkjet owners. This printer is also less prone to clogging in the nozzles thanks to some improved engineering.

However, the settings menu includes several anti-clogging cycles that can be run if (or more likely, when) dried up ink stops you printing. Epson includes a one-year, or 100,000-page warranty with this model.

What you may well have to replace is the maintenance box when it eventually fills up with the tiny amounts of excess ink generated by printing and cleaning. A replacement costs around ten dollars and it looks to me like you could save money by emptying and cleaning the existing one.

Epson EcoTank ET-4950 series: Final verdict

The Epson EcoTank ET-4950 and its variants proved that Epson is the brand to beat in this refillable office-friendly mid-price category. I found it easy to set up and operate thanks to the responsive touchscreen and good design and it has all the features I consider essential for the home worker or small shared office.

In other words, it duplex prints pretty quickly, connects readily my 5GHz Wi-Wi and turns out crisp and colorful test pages on all kinds of media. I also appreciated the two-sided scan feature and, of course, the generous amount of inbox ink.

Does Epson still make the best ink tank printers? This category only gets more competitive with new players like the significantly more affordable Brother DCP-T780DW entering the fray, while the excellent HP Smart Tank 7001 comes with larger ink tanks and the Canon MAXIFY GX4020 offers superior print quality.

But with more features than those rivals, and such a strong all-round performance, I can highly recommend the Epson EcoTank ET-4950 series.

For more top-performing models, I've tested the best home printers and the best all-in-one printers.

ProtoArc has been around for a while now, and they have a handful of items I have reviewed over the years, like their EC100 chair and a few keyboard / mice solutions. They have been impressive through and through with putting out quality gear for a shockingly low price every time.

This chair, the Flexer Pro, is no different. It had a quick and easy assembly that only took about 5 to 8 minutes to assemble, it has surpassingly breathable mesh on the backrest, featuring FlexWeave tech to cool you off on hot days or if you simply run warm like I do, and it has a great set or armrests. Right there, if those things are done well, the chair is already going to win people over. But, beyond that, this chair has some things I have never seen, such as the dual lumbar support. That’s something that even some of of my premium chairs don’t have.

Flexer Pro also excels in not being “too much” as a chair. Given it's only available in the US, and the dual lumbar support can take some time to adjust to, it's unlikely to make our round-up of the best office chairs. But it's simple and elegant in design, while still offering maximum comfort for up to 10 hours according to ProtoArc, and, in my testing, I can say that this chair surely lives up to the hype.

ProtoArc Flexer Pro: Price and availability

At the time of review, the Flexer Pro is currently on sale for $312.55 (was $399.99) on ProtoArc’s website. It's also available on Amazon.com in both black or white variants, with the former being $299 and the latter priced at $315.86.

From what I can see, the chair's only available in the US right now.

One thing that I always pay attention to for chairs like this is the warranty. After all, an office chair is an investment, even at the low- to mid-range models like this one. So, I was pleased to see ProtoArc offering a 10-year limited warranty.

ProtoArc Flexer Pro: Unboxing and First Impressions

The packaging was minimal and simple, yet enough to keep everything well-packaged, safe, and secure. As I mentioned above, this chair took a mere 5 minutes to assemble by myself. It was incredibly easy, no special tools necessary outside of what was sent with the chair, and no points of frustration.

After getting everything set up, I like how simple this chair is. A lot of chairs have a lot of things going on. The Flexer Pro keeps it simple. It’s a cushioned seat, a mesh back, good armrests. That’s the core. It’s clean, straightforward, and great for most.

ProtoArc Flexer Pro: Design & Build Quality

The dual lumbar supports are the stand-out feature of this chair for me, it seems like such a small thing, but in practice and in use, it’s super helpful to be able to add that support in two slightly different, or one larger spot on some days. I do find that some days I will adjust this and have it be slightly different, but perhaps I’m alone in that. Regardless, having that functionality in a chair at this cost is still wild to me.

Further, the cushion and backrest make for a very breathable sitting experience. As someone who runs fairly warm, I really appreciate having a chair that can breathe with me and help keep me cool even on hot days or during long working sessions.

Another thing that I really appreciate is the lack of over-the-top branding on this chair. I have some chairs that will remain unnamed, but they blast their branding everywhere, loud and proud. That ruins the professional feel of a chair immediately, so having this chair minimally branded and that is all is fantastic.

The armrests, crank tilt-tension control, seat depth slider, and 130-degree recline are all fantastic features. Again, these are features I’d love seeing on chairs worth three times as much, so seeing this in a quality chair at a budget price is a spectacular surprise.

ProtoArc Flexer Pro: In use

My team and I have rotated using this chair for the last 88 days at the time of writing. In that time, we have used it in my studio space, in some home offices and in both scenarios this chair has performed wonderfully. The chair is comfortable for even extended desk working sessions, it’s easy to kick back when we want to stand at our standing desks and if we maybe don’t get to stand that day and rather need to lay back, the 130-degree tilt makes it super comfortable and easy to grab a quick rest.

While most of our testing has been done during the harsh Midwest winter in the States, sometimes that means that with the heat on, your house is warmer than normal (depending on the person). For those days, or the harsh summer afternoons, having the mesh backrest is a wonderful two-thumbs-up for this chair. It means that I won’t stand up to find my back stuck to my shirt.

Another thing that is really nice is that since this chair doesn’t have a headrest and has a fairly compact frame, I can push this chair under my desk rather than just kicking it behind me if I am short on space or don’t want to get my chair too far away from my desk.

After three months' use, the felt still looks brand new, the mesh backrest has held up wonderfully, and the armrests still work well. No issues so far, and none in sight.

ProtoArc Flexer Pro: Final verdict

Not everyone who is looking for a chair is looking to spend thousands, or even close to a thousand. Some want a simple chair that gets the job done. The ProtoArc Flexer Pro is an easy recommendation for those people, as it’s budget-priced yet adds features you usually only see in high-end flagship chairs.

The quick assembly time is a real bonus - ProtoArc estimated it's a 10-minute job, but I did it half that time. Airflow, comfortability, and support are all good. And I'm pleased how well the chair has held up after using it for three months.

That dual lumbar support, though, may not be to everyone's tastes. I can understand that. I would've also liked to see greater availability beyond North America.

But the chair's nicely designed overall, with all the adjustability mechanisms I'd expect to find one priced this low. A solid choice for working from home or in the office.

For more office furniture, I've tested the best standing desks.

ProtoArc has been around for a while now, and they have a handful of items I have reviewed over the years, like their EC100 chair and a few keyboard / mice solutions. They have been impressive through and through with putting out quality gear for a shockingly low price every time.

This chair, the Flexer Pro, is no different. It had a quick and easy assembly that only took about 5 to 8 minutes to assemble, it has surpassingly breathable mesh on the backrest, featuring FlexWeave tech to cool you off on hot days or if you simply run warm like I do, and it has a great set or armrests. Right there, if those things are done well, the chair is already going to win people over. But, beyond that, this chair has some things I have never seen, such as the dual lumbar support. That’s something that even some of of my premium chairs don’t have.
