Office Desk Chair, Ergonomic Computer Office Chair with Adjustable Headrest and Lumbar Support,High Back Executive Swivel Chair (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.

I only make an effort to write a review when I think it’s truly required—and in this case, it definitely is. This chair is absolutely worth it. I do have one small critique, but honestly, for the price, it’s barely worth mentioning. Still, for complete transparency, I’ll include it. 1. Assembly This chair is the easiest thing I’ve ever built in my entire life. Not only do they include clear instructions, but they also provide a YouTube video to walk you through it. If you follow that, you’ll have it done in no time. On top of that, they include the tool for the screws—and it’s not some cheap little L-key. It’s actually a solid, well-made tool that makes the whole process easier. I’ve built chairs before that required all kinds of jiu-jitsu tricks just to align the parts, but this one came together perfectly. 2. Quality of Materials The materials are genuinely high quality. They invested in the areas that matter—seat, back support, legs, the whole structure. Nothing feels cheap or rushed. 3. Adjustability I’ve seen some complaints online, but honestly, this chair adjusts exactly the way you want it to. It leans back, goes up and down—everything you’d expect. If someone can’t figure out how to operate it, that’s more of a user problem than a chair problem. 4. Design It’s just beautiful. As we get older, we don’t want to be full-grown adults sitting in racing-style or overly “gamer” chairs. We want something more mature and classy, and this chair nails that aesthetic. 5. Wheels The wheels are perfectly fine. They’re standard office chair wheels—they move when you push them, exactly as they should. I don’t know what some people are doing, trying to race around their house or perform NASCAR maneuvers, but calling these wheels “low quality” is wild. They work exactly as intended. 6. Comfort The comfort level is perfect. It has great lumbar support, and the mesh material keeps you cool instead of heating you up. If you have bad posture, this chair will genuinely help improve it. Trust me—your back will appreciate it. Finally, the critique The armrests go up and down, but they don’t swivel. This is the one area where they trimmed the quality a bit—but for the price, it’s completely acceptable. The arms aren’t bad at all; they’re just not multi-directional. If you want fully adjustable 4D armrests, you’ll need to look elsewhere. But for what you pay, this chair is basically perfect. I just wanted to put everyone at ease, because I know how overwhelming it is trying to find a good chair in this endless sea of options. This one genuinely deserved a review, especially for one small detail: For absolutely no reason… they included gloves. I’ve never seen that before, but it shows they care. Honestly, this is a phenomenal company—you can tell they took their time making sure the engineering on this chair was done right.

I have had this chair for over 4 years now. It is still strong and working. It has provided ultimate comfort this whole time (4 years) - over long gaming sessions and 8 hour Work-From-Home sessions. Back support is great, head support is great, and it does not squeak/make high pitch noises when turning. Over the last 4 years, one issue I have had, is that the arm rest cusions have been falling apart and I find sponge on my floors every so often. The second issue, is that the bolts come lose and the chair makes an annoying sound until you screw them fully back in again. Overall, quality chair that has outlasted any other chair I have had. P.S. The price is still the same as I bought it last (current price = £170 (British pounds) or $240 (American dollars).

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've been using the SIHOO Office Desk Chair for nearly 4 months now, and I wanted to share my thoughts on this product. In the past, I had always owned executive chairs, which were comfortable but lacked adequate support. This wasn't a problem before, but over the last year, I started experiencing discomfort in my lower back and hips after sitting for extended periods of time. It seems like age is catching up with me! My previous chair was falling apart - the faux leather was peeling off and making its way around the house, and there was no padding left in the seat. Within an hour of sitting, I would noticeably sink 8 inches lower than when I started. So, it was definitely time for a new office chair that could provide better support. I spend a significant amount of time at my desk each day, so finding the right chair was a priority for me. As someone who is over 6 feet tall and overweight, I knew I needed to do thorough research before making a purchase. After reading the reviews for this chair, which were generally positive despite a few minor issues and complaints about size, I decided to take the plunge. It seemed that any concerns raised in those negative reviews had been addressed with refunds. The chair arrived well-packaged and was quite heavy. I unpacked it at the bottom of my stairs and carried each part individually to my office. The assembly process was straightforward, and all parts were included - a good sign right from the start. While an Allen key was provided, I opted to use my own tools for final tightening, just to ensure everything was secure. Attaching the wheels required a bit of careful handling, but it wasn't any more challenging than other chairs I've put together in the past. All bolt holes lined up perfectly, eliminating any need for excessive force or adjustments. The online assembly video provided by the manufacturer proved to be incredibly helpful and comforting throughout the process. Once assembled I could see the quality was very good. I had read some other reviews that said otherwise but I can't see why. I have always spent up to £200 on chairs and this is of superior quality to anything else I have owned. I suppose if you are used to £2000 chairs then this might fall a little short. The wheels glide quietly, and there is very little movement side to side, even after 4 months (remember I am over 6 feet tall and overweight). Ergonomically this chair is fantastic. At just over 6 feet tall I did find this chair a little shorter than I was used to but I did some research and took some measurements and discovered it was actually the correct height for me and I soon got used to the new position. I think all those executive chairs I have lounged around in previously had skewed my expectations. The lumbar support, again something I had not experienced before, took some adjustment to find the correct and comfortable height but once I found the sweet spot and remembered to not slouch into it, the benefit is obvious. The headrest is fine for my height but it is fully extended. The arms adjust easily and they are nicely scalloped so my arms nestle in them which is nice. The recline feature is not something I use as I mainly have the chair locked into a correct seating position but on the odd occasion I have released it I felt comfortable and secure thanks to the large wheelbase. I have also found the mesh is brilliant on hot days, far superior to real or faux leather. To sum up, I have used this chair for on average 8 hours a day for 4 months, I am tall and heavy but the chair shows no sign of deterioration at all. My back and hip issue has all but gone and I am confident that any aches and pains I do suffer from now are not chair related. I do very much wish I had ordered one of these style chairs many years ago!

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.

Bought it based on the reviews. Easy to assemble. Looking nice. In terms of how comfortable it is I would rate it ok. It didn't live up to its hype but at the same time the price is reasonable. Far from the best chair but it's ok

Really comfortable to sit on for long periods at a time. The pink is really cute and fits well with my pink setup. Unfortunately, the backrest did come ripped out of the box as the parts were really packed in the box… so I don’t know if another part tore the backrest… besides that the price for what you get is great reclines nice and has good back adjustments.

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

Very comfortable chair with well packed item i love it !

Great quality, sturdy, comfortable. Comes with clear instructions and everything you need to assemble. Highly recommend, definitely worth the money 😊

The product is easy to assemble and it was delivered earlier than originally indicated at the point of placing order. The chair is very comfortable and has different settings to cater to individual comfort level. You'll not regret buying the product,
