"All of this amounts to a really crazy experience when it comes to the arm adjustability. Most chairs have a completely flat arm but with this the sweep seems to give a little bit more support to my whole arm rather than just my elbow which is rather nice."
★★★★★
"These flexible plates allow the Doro S100 seat to be tilted smoothly and at any angle for resting, then returned to the initial position without any effort or twisting of the back."
★★★★★
"...with an “anti-gravity mechanism” that allows the chair to smoothly move and stop at any angle without needing to be locked into place."
I work in occupational health and after a lot of searching, this chair seemed like the most affordable and ergonomic chair on the market. After trying for a few weeks, I think that's true. The only time I experience discomfort is when I sit with poor posture. Used correctly, it is great for people without any existing musculoskeletal issues

Its really great chair and sturdy! I like it. The only downside to point out is the lumbar support. Not sure but its place too downward so doesn’t really make big changes and the adjustment is only limited to push and out.

I’ve owned the full mesh version of the SIHOO M57 since October 2021, and it is easily the best chair I’ve ever had.
Most chairs start to sag or creak after a year, but even 3 years in, this chair still feels like new. The build quality is incredibly sturdy, and the mesh hasn’t lost any of its tension—it’s just as supportive now as the day it arrived. It’s rare to find furniture this well-made that actually stands the test of time.
I’ve recommended this chair to everyone I know. If you want a breathable, durable, and high-quality mesh chair that won't need replacing after a year like many others I've had, this is my 10/10 recommendation!"l
Silver Kato M.5/5
Definitely recommend this chair.
Delivery was swift and the chair extremely simple to assemble. It has all the adjustments required and is extremely comfortable, the wheels are great and works well on a medium pile carpet too which is great.
Dean M.5/5Verified
Good quality for money! I recommend it!
Mehrdad A.5/5Verified
Good one.
The mesh is a bit rough. Might not be everyone choice. Chair is quite heavy.
Madhura V.4/5Verified
Im sitting more correct now, but keep in mind it is still a discount chair. Feels kinda cheap

Domenico4/5Verified
It's a nice looking and comfortable chair. Quite heavy, but that shows how robust it is.
For me the seat is a bit on the long side and the wheels don't roll so well on my wooden floor.
My first days on the chair went without pain in the back so that's great.
Paul V.5/5Verified
MI principal queja de esta silla es respecto a su asiento debido a que el plástico que sujeta la malla del medio esta al descubierto y si eres una persona grande o te gusta abrir mucho las piernas te lo vas a acabar clavando

I have been in the need for a new office chair since starting a WFH job. I found this chair via Reddit, and decided to give it a shot. So far, it has been well worth the money! It is very comfortable and I love the adjustability of both the headrest and lower back support. Additionally, the recline aspect adds to my enjoyment of this chair, even though I don��t use it too much.

pour l instant c est parfait
Leo D.5/5Verified
I really like how comfortable the chair is. The lumbar and cervical supports are great. I do wish the lumbar and cervical supports wouldn't change location when the chair reclines, and that it wasn't as easy to recline the chair. After a little research I found that pulling out / pushing in the adjustment lever will lock in the reclinement angle, a feature that definitely makes the chair acceptable.

I bought the SIHOO M57 Ergonomic Office Chair 4 years ago, and it��s been a fantastic investment. I use it over 8 hours a day, and it has held up remarkably well.
Recently, I had a minor issue with an armrest, but customer service quickly sent a replacement, and now the chair feels like new! The build quality is impressive, the seat is comfortable, and the tilt function is great.
Overall, this chair has exceeded my expectations in comfort, support, and durability. Highly recommended for anyone needing a reliable ergonomic chair
Amelia S.5/5Verified
The chair is fine but one piece arrived cracked.
Fawer G.4/5Verified
Chair arrived. Instructions were clear. Chair was built successfully (with no swearing). This is why we pay you the big bucks.
Iain C.5/5Verified
Easy to build. Took a bit of adjustment to get the comfort right. Sitting much higher now so need foot support!
Phil M.4/5Verified
It is the most comfortable chair I have ever sat in to work at my computer. I love the mesh that keeps me cool, the headrest which I can lean back on a close my eyes for a moment, the fact that the armrests are adjustable and therefore I do not require extra padding so as to reach keyboard and mouse. just love it.
Dorothy M.5/5Verified
Definitely a great chair, would recommend. It's helped keep me sitting better and reduce back pain. Excellent customer service, I would recommend this company.
Dominic5/5
Great chair, sturdy but very comfortable as an office chair. Great support and breathable material makes it comfortable for long sessions sitting. Has adjustable lumbar support,
neck and height. Highly recommend.
Hamel P.5/5Verified
Chair is so comfortable!
Joshua H.5/5Verified
Comfortable and sturdy chair! Ready fast delivery too
Tracey P.5/5Verified
It has solved my back pain in a matter of days! The material is like nothing I've ever seen before. It's thin but strong, it's soft but supportive, it grips you into the chair whilst being smooth and bouncy. You can really recline in it whilst you take calls or have a break. Plus, all of the settings are easily adjusted to suit anyone. I tightened up the back a bit, and the chair does all of the work for me. Amazing, and great value, after I'd initially thought it was a lot to spend on a chair. I'd recommend it to anyone who sits at a computer for any length of time on a regular basis.
Sam W.5/5Verified

Easier than expected to assamble. Really comfy.
Ozgur T.5/5Verified
Very happy with the chair. It arrived quickly and was straight forward to assemble. I am finding it easy to sit in all day while working and the mesh is so much cooler than my old non-mesh chair. It's a good chair.
David P.4/5Verified
Safe delivery, box a bit damaged but that wasn't a problem. Heavy and looks like good quality materials.
Vasile A.5/5Verified

Adina B.5/5Verified
Really good for my posture
Karl S.5/5Verified
I am finding it difficult to make this chair comfortable because I have a lot of shoulder and neck aches since using it. So not convinced.
Aidan E.3/5Verified
So far so good 😊. It took a while to get the lumbar adjustment to fit to my requirements. I particularly like the head rest but it should be sturdier. I love the mesh material and looking forward to how it will keep my body cooler in the Summer 🌞.
