Had it for a few weeks and enjoy. It's firm but comfy and moves around pretty well. Upgraded the wheels to some caster wheels but the seat itself is perfect for my needs. If you want an inexpensive office mesh chair this is a good choice.
My bum is so comfy in this chair great back support. Very roomy which is perfect for when I cross leg sit. Mine arrived obviously used nothing was wrapped hairs on the back rest and screws in a ziplock bag. Everything in the box though. No scratches or dings that I can see. Overall happy with the purchase.
The chair seemed to be sturdy and of decent quality. The seat was uncomfortable for me after just a couple of hours and I need something to sit on all day while I work from home. The lumbar support was adjustable height wise but not in any other way and it stuck out a bit too far for me. Also the lumbar support would move down anytime I leaned back to stretch. I tried it for a couple of days and now I'm returning it. I would possibly recommend this for someone who has already tried a mesh seat (no cushion) and liked it but I would tell most people to keep looking. It was fairly easy to put together just not comfortable. Also disassembling it to return has been a pain as the base does not want to come off the hydraulic lift mechanism.
