Comfortable chair and seems to offer good ergonomic support so far. I have been able to sit on it for several hours at a time while working my desk job from home. It was pretty easy to assemble as well. It's also a great size for me (6' tall 190lbs). The mesh texture is somewhat abrasive on bare skin though (i.e. if I sit with my foot under me or wear shorts) and the head rest so far has been unnecessary.
This is a great office chair. I like that it helps my posture. Self assembly wasn’t bad for a novice like me. The kit did have a missing screw in section B.
