Sihoo M57 Ergonomic Office Chair Grey Mesh

Overall I think it's not too bad for the price. Mesh base and backrest is great for the hot and humid weather. Was worried the base might be hard because it's not memory foam or cold cure foam but it actually feels quite comfortable.Lower back support is alright although it is made of hard plastic covered by what seems like a thin layer of normal sponge and mesh cloth. Good thing is that it can be adjusted up/down and forward/backward to find your sweet spot.The tilt angle is much better than I thought. Allows me to lean back sufficiently for a quick shuteye, compared to e.g. Ikea Matchspel gaming chair.Like the fact that the base slopes slightly backwards so that the whole body slides into the backrest and lumbar support for better support. Feel a lot more ... MoreOverall I think it's not too bad for the price. Mesh base and backrest is great for the hot and humid weather.

Feel a lot more comfortable sitting in this chair.Build quality could be better but then it's not in the price range as e.g. SecretLab. Adjustments to lumbar and neck support is primitive - by simply pushing down or pulling up. There are no buttons to press.

So far it’s perfect

I don’t know how many people will read this but if you’re looking for a full mesh chair I would pick this one again. I have always had issues with my computer chair the main one being sever coccyx pain. This chair has but eliminated this pain for me. I can sit in this chair for hours with no issues. I have had some pain with this chair but it infrequent enough to lead me to believe my posture is bad. 99% of the time I use this chair for more than 3 hours without standing I feel no pain anymore and that alone for me makes this chair worth every penny. It comes with the tool to assemble. Assembly was a breeze, less than 15 mins from box to fully assembled. The tilt and adjustable armrest are perfect in my opinion. The casters and base are very heavy and feel of high ... MoreI don’t know how many people will read this but if you’re looking for a full mesh chair I would pick this one again.

The casters and base are very heavy and feel of high quality. The mesh has yet sink or warp in anyway I weight close to 230lbs so I’m on the upper side of the chairs weight limit and it feels solid as a rock. If you want or need a chair or need an idea for a Christmas gift and don’t have $350 to spend this is a fantastic choice and I would definitely buy it again.

not happy

Assembly of the arms-to-this chair %26 then to the seat was a tremendous struggle. (One) needs a work bench to assemble this chair. The more difficult parts should have been pre-assembled by the mfc. The rest one person could do, on their own w/some perseverance. The hand held hexa screw tool will make you take longer to assemble the parts. /best use a good screw gun or drill w/ screw tip attachments. Could not use the head rest. (doesn't work for me. Not enough range of motion.) Could not use lumbar support. (not enough range of motion (for me). Flip up arm tests Are convenient, but the side to side twist motion is Not necessary. However, I Am keeping it. Been wanting an ergonomic chair for a very long time. Use my own seat %26 back to assemble this chair.
