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

My previous chair, although still looking pretty good for its age (well over 10 years) , had started to dig into the back of my thighs as the seat cushion was rapidly losing its support. Time to go shopping. The colour of this caught my eye - but then I've always loved a bit of colour - and I also liked the style. What convinced me was the description that explained how the seat cushion was shaped so as not to dig into the back of your thighs and the video showing the simple assembly. Decision made. Chair ordered. I immediately began to feel a little excited at the thought of replacing my old, armrestless black office style chair - that's served me well, although, I didn't actually buy it and it wasn't what I would've chosen, had I done so. Less then 24 hours later, the chair arrived and on opening the box I was immediately delighted with the colour and style-even before I'd assembled it. A huge upgrade over my previous chair and much more 'me'. The simplicity of assembly was just as I'd expected after watching the video, which was great. I was particulary impressed at the simple idea of having extra screws and washers as standard. Something I've often thought would be a good idea, as I've experienced the odd situation where insufficient were supplied - or something were a little damaged and un-usable. At 5' 10" with short legs, the lowest setting for the seat height, armrest height and lumbar support are perfect for me. I'm a little longer in the body but the headrest has only been raised a modest amount within its range. This makes me feel the range of adjustments would accomodate people who are quite a lot taller. Comfort wise, I'm also delighted. Whilst the feel of the seat when you sit on it is quite firm, I have my own business and work from my home office, so, I'm using it pretty much all day, Monday to Friday and sometimes at weekends, as well. I've found it to be really comfortable and have no problems if I sit in it forhours on end, which does happen when I get into the flow of work, although I do like to get up and stretch my legs periodically. This is a great purchase, it was excellent value, feels good quality and I couldn't be happier. The chair met all my expectations based on what I saw prior to purchasing it. Comfort wise, you really can't tell from a photo and so I had none. But I'm also really pleased at the comfort. Oh, and I've found the recline positions are really good, too. Wimbledon's on, at the moment, and whilst I could easily watch it all afternon, I exercise a little self-discipline and don't watch much during working hours. The exception is over lunch, wher I might watch for half an hour or so. Sitting reclined, using my desk as a foot rest (don't mention that to my better half) and eating my lunch whilst watching a bit of tennis has been exceptionally comfortable. Happy days!

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.

Overall I really like this chair, assembly was easy and everything needed was provided, including one more screw and washer than needed for all of them and even a pair of gloves, took about 10 minutes to put together alone. The chair is comfortable for long periods of time, lumber support is good and adjustable and have not had any discomfort sitting in this for 8-12 hours with only small breaks, the cushion is fairly thin but it is still very supportive and comfortable. I have two small complaints with the first being very negligible that the arms have no forward/back adjustment, its clearly advertised that it don't have it and only had up/down adjust (and in a way in/out adjust with being able to screw it onto the base closer or further out) I would not deduct a star for this and it is very minor. My only serious complaint about this chair is the headrest, there is some left/right sway when you have it on the higher settings and its also a little too easy to move it with medium pressure when resting your head on it, it is still a relatively minor point but I feel like this is worthy of docking a star from an otherwise amazing chair. Overall very good product and I think you would really struggle to find a chair as good at the price point, I got it on sale and I wouldn't have begrudged paying full price.

I am giving 4 star because the height is not high enough for me.

Very easy to setup and instructions were pretty simple to follow. Plus they have video instructions that you can scan on the manual to get. A VERY comfortable chair that lets you lie back and relax with ease. This is my first ergonomic chair ever, so I’m really impressed. Plus it’s a HUGE upgrade from the chair I had before (picture attached).

One of the nuts was completely loose in the seat. I will have to fix it myself.

Der SIHOO M18 hat meine Erwartungen an einen ergonomischen Bürostuhl absolut erfüllt. Die verstellbare Kopfstütze und Lendenwirbelstütze sorgen für eine individuell anpassbare Sitzhaltung – gerade bei längeren Arbeitsphasen eine echte Entlastung für den Rücken. Die hohe Rückenlehne unterstützt die Wirbelsäule optimal, und das atmungsaktive Mesh-Material fühlt sich auch an warmen Tagen angenehm an. Alles wirkt solide verarbeitet, die Mechanik läuft ruhig und zuverlässig. Auch die Montage war unkompliziert – in unter 30 Minuten stand der Stuhl einsatzbereit. Besonders gut gefällt mir das moderne, unaufdringliche Design in Dunkelgrau. Der Stuhl passt perfekt in mein Heimbüro und bietet ein sehr gutes Sitzgefühl – selbst nach mehreren Stunden. Absolute Kaufempfehlung für alle, die viel am Schreibtisch sitzen! 💼🧘‍♂️

Great value for money. Assembly is relatively easy but can be a bit confusing. The product is sturdy and provides ample support. Cushion may feel hard initially but settles well. Way better than many other brands that I have tried and gives comfort similar to Herman Miller chairs - unsure about durability. Only issue I have is with the headrest. It was too tight to go into the slots and I had to remove the holder to fit it. It is still a bit too tight to adjust easily.
