M18 Office Chair Ergonomic Desk Chair, Breathable Mesh Design High Back Computer Chair, Adjustable Headrest and Lumbar Support, Upgraded to Rollerblade Wheels (Black)

I’ve been using the SIHOO M18 chair daily and I’m genuinely very satisfied with it. The build quality is excellent, everything feels solid, well-designed, and properly engineered rather than flimsy like many chairs in this price range. The chair is very comfortable, especially for long sitting sessions. The lumbar support is firm and supportive without being intrusive, and the mesh back keeps good airflow. The seat base is stable and does not wobble, which gives confidence in its durability. Assembly was straightforward and all parts fitted precisely. Once assembled, the chair feels sturdy and balanced. The adjustment options allow you to find a comfortable position easily. Overall, this chair offers excellent value for money. It feels reliable, supportive, and suitable for daily use over long periods. I would definitely recommend it to anyone looking for a quality ergonomic chair without spending excessive amounts.

comfortable, easily put together, the rollerblade style wheels make it roll smoothly and the locking recline feels reassuringly solid, when set upright the back support realy helps comfortably correct my posture preventing the end of day slump back ache.

It's massively better than Songmic Office Chair Ergonomic OBN52BKUK, which I bought for the spare room (although one might expect all these things are built in the same warehouse and designed by the same people). Like that, the Sihoo is limited and a tad flimsy around the arms, but overall, unlike the Songmic, it's overall a more comfortable sitting upright experience. The rollerblade-style wheels, which I'd never seen before on a chair, are of particular note: combined with the chair being fairly light, it's very easy to move around, it's like gliding, even on carpet. Ultimately, it is a cheap office chair, you go into it not expecting the best build quality, but to its credit it has decent lumbar support (far better than the Ikea Markus it replaced, and the Songmics), and just as crucially, a semblence of a headrest with a decent range of movement, which the Songmics lacks entirely. Frankly, I've used far, far worse chairs in professional offices back in the Before Times. Build is pretty easy, and the package includes a spare of everything, and an actually useful allen key with a big grip. I'm hanging on to that for future reference. My only real negative, even at this price point, is that while the back recline options are limited to two additional fixed positions as may usually be the case in these types of chair, neither of them feel right: even the 2nd position is a too far back for my taste, especially given the seat reclines with it, so it lifts your feet off the floor and you have to reduce the height, which is awkward as both are controlled by a single, dual-function lever. Still, for £136, and knowing the mesh will inevitably be torn to shreds by the cat in a few years, as happened to the Markus—hence why I can't risk even a second-hand Aeron—I don't think you'll be disappointed. Have low expectations, it will beat them easily.

Review of Sihoo M18 Office Chair purchased from Amazon UK for £139 in May 2026. This is an excellent chair, it went together easily, no problems with missing screws or badly drilled holes. The seat is firm but it's not uncomfortable and I understand it gets softer over time.-, there's adjustable incline which can be locked in different positions. I just leave it unlocked to rock back and forth. There's also adjustable lumbar support (up or down/ in or out). I'm 5ft 11inches tall and love this Sihoo Chair, it fits perfectly and is very comfortable. Reccommended.

I purchased this chair in 2022 whilst searching for an ergonomic office chair with skate-style wheels, as I had read at the time that this type of wheel causes less damage to carpets. Three years on, in 2025, it still looks as good as new with no issues whatsoever with any component. The comfort, durability, and appearance are all exceptional. Due to the nature of my work, I spend many hours at my desk, yet I've never experienced a sore neck or back thanks to this chair's excellent ergonomic design. Recently, I contacted Customer Services after my headrest was damaged during a house move by the removal company. Despite the 3-year warranty having just expired, they kindly offered to send me a replacement headrest free of charge, which demonstrates their amazing customer service and commitment to customer satisfaction beyond the warranty period. I would highly recommend this chair to anyone seeking a quality, long-lasting office chair with exceptional after-sales support that goes above and beyond expectations.

Decent chair, definitely a good option if you are budget conscious. Only thing really letting it down is the fact the wood board under the padding isn't that supported by the arms or the front so you have to be careful with how you sit. Given I fidget a bit when sitting, I was shocked to hear a crack when I was moving back onto the seat. No visible damage but does make me concerned if it might fail in the near future after 3 months with it. Wheels are great, no issues on carpet. Height is perfect for most office spaces and the seat padding is comfy enough for long sessions.

Great quality chair, very comfortable and easy assembled (about 15 mins) We purchased 4 of these chairs for our office. They arrived very quickly. We purchased these as some complained about back issues with our old seats & these ones give great support and seating position with adjustable back support head rest etc. They are of very good quality and build, they where a little low for our taller staff so we contacted customer support to see if they could advise on anything. They were brilliant, replied straight away and advised they could send out a higher gas lifter free of charge. We received these a few days later, fitted them and they did the job perfectly. Everyone is more than happy with there new chair. We can not fault these chairs or the level of support that was offered and delt with from SIHOO. Best customer support we have ever had! Would definitely recommend these office chairs.

Like anything flat packed be prepared to lose 20-30 minutes of your life. The good news every set of bolts include 1 extra. The wheels glide but could be better. Chair is comfortable and easily set, the lumber support work well but the adjustment could be improved, that said once correct you won’t move it again. Head rest is the same not the best height adjustment but once set is fine. All in all a comfortable office chair, only used for 2 days so far so this review is only rating initial build and use.

I bought it in 7800, its very good chair in this price, quality is very good too.

VERY quick shipment. The delivery took only 4 days Instead of 12 – 21 as the delivery notification indicated. Very easy to assemble. Expect 30 minutes and you can take it easy. Mount the parts in a large place and then move the finished chair where you want it in two parts, bottom part and top, it is quite easy. The chair is quite comfortable with the nice lumber support as a plus. The slope of the backrest did not work at first, the latch had locked in on position. After some trickery, it let go and now it works. The only negative thing is that it cannot be raised any more. I’m 190+ cm and think it is in the too low even fully raised. I'll will try to find wheels that are higher, would need 5 cm extra. How it lasts over time is hard to say but the construction is robust and well made so I have good hope.

For the price of this, you wouldn't get a better chair. It's solid and it has features that you usually only find on more premium chairs. The pros: - The wheel base is metal (even the wheel brackets themselves are metal) - The wheels are the same as what you find on roller blades. they're very good quality, very silent and smooth when moving around - The padding on the seat is thick and comfortable. I've had it for a good few months now and I work mostly from home and it didn't go out of shape - The reclining options are good. you can lock it into a reclined position or leave it open. you can then adjust the tension from underneath for how much weight / force it takes to recline - When you do recline, the back reclines more than the seat so it feels more natural. the arms are attached to the seat base so they move with the seat (not the back) - The arms can adjust up or down The cons: - There is a lumbar support on it which doesn't have much padding. luckily you can adjust it, so I have it back fully and don't notice it there. - It would be nice to have more adjustment on the arm rests. It can be put up or down, and the padding of the rests are shaped so your forearms won't slip off. The problem is that they don't turn, so when you're typing or using a mouse, the padding on the armrests don't feel too comfortable. This is why I gave it 4 stars instead of 5
