I have a fused spine and struggle with back pain and this chair keeps me comfortable for 10 hours a day 5 days a week. It's better than I expected and assembly was easy.
The chair is very comfortable and the dark brown color is perfect for my "office" setting (part of a larger room). The sales people in the Downingtown PA Staples store were especially helpful and the chair was assembled at my request ready in less than an hour.
