I was looking for a new chair that would provide support for my lower back as I suffer quite a bit from lower back pain. So far this has solved that problem for me. I do spend about 6 hours a day sitting and I've noticed in the evening I haven't been in pain like I was in my old office chair. The reason I didn't get it 5 stars is that while it does recline it is really hard to do so. The mesh is also uncomfortable when directly against your skin as well. So as the summer months approach I'll probably have to cover the mesh with a blanket if I want to wear shorts. In regards to assemble overall it was easy but I did need help getting the wheels into the base.
Excellent chair very comfortable. My only complaint is on putting it together. I found it to be no problem until the head rest. For some reason lining that up gave me difficulties. It was probably me.
This will be a first impression because I've only owned it a week. Chair is very comfortable supportive. One reason I chose this over other chairs is the head support. I sat in every other chair at the store and realized how much I liked the head support over no head support. I like the mesh because I don't stick to it in hot humid weather unlike my previous faux leather chair and the mesh allows air to circulate around me. By the way I ditched my faux leather chair because the seat covering was "dissolving"! It was akin to peeling off dead skin after a bad sunburn UGH! Anyway I will wait to see how well this chair and its materials will hold up over time.
