If headrest had been adjustable in height to a greater degree I may have been able to use it. As it is that part had to be put aside which makes the chair a functional but not complete package compared to the whole I was imagining when I bought it.
I bought this chair after trying a friend's and did not regret it. It's very adjustable and very comfortable which is what I need since I do a lot of sitting. I sold my original purchase when I moved across the country and bought a brand new one immediately. I like how cooling the mesh is how much lumbar support there is and that there is neck support. A couple of weeks in a tiny piece of the mesh broke and was poking me but I clipped it with nail clippers and had no further issues.
The chair is decent and about the same comfort level and quality as similar chairs elsewhere. Unfortunately that also means the tilt and pneumatic levers are prone to snapping due to being mostly plastic in design as has happened on two occasions now. I regret not choosing a more solid model like the Tempur-Pedic 6400.
