The chair is easy to assemble using the included allen wrench. I like the tilt of the back. It looks uncomfortable but when you are sitting in it the back and headrest give good support while not being too stiff. I'm 150 lbs and it holds my weight without losing height but I'm not convinced it would hold if I was over 200. Haven't tested that but just my impression based on using the chair. Overall pretty comfortable for my office use.
