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.
The chair is comparable to the much more expensive all mesh chairs that are on the market. Have been using it for a few weeks now and love it. My back and my neck are very well supported and certainly helps alleviating the pains I was experiencing with my old chair. Would highly recommend it.
