The chair is really good for the price and it fits me pretty well. At the time I am 5 feet 6 inches tall. I would say if I was around 5 feet 8 inches tall it would fit me better. Overall it is a really good chair and the building process took under an hour. The chair can also recline a little it has adjustable head/neck support and lumbar support. The chair is on wheels so it can move around and it can turn/spin. There is also height adjustment features.
Pros: Good lumbar support (a bit adjustable as well) Descent quality Comfortable Cons: 1)Headrest not adjustable by height I'm 6.1 and in straight position I'm touching headrest with my shoulders (which a bit annoying so I had to remove headrest) . This is probably biggest complaint about this chair. 2) Mesh at the sitting is a bit hard if you sitting in shorts and expose your skin it might get uncomfortable (or some shorts/pants which are very thin .. i.e. leggings if you are women) Overall it is pretty good value tried many chairs from 200$ to 1200$ (I was ready to pay even 1000$+ if I would find something what I really like). My biggest complaint about other chairs was lumbar support I found this one most comfortable for me. It is not perfect but surprisingly it was the most comfortable chair for me (I work 8+ hours on it). I didn't try herman miller aeron since I wasn't able to find it at the store if I like it probably will replace this chair.
I purchased this chair to replace my leather executive chair that caused severe upper back pain while I worked at my computer. This chair is comfortable and more ergonomic; I now have no more pain even after sitting long hours.
