This chair is great comfy and provides great back support. If I have to give any downside is that the arm rests are not cushy enough for me and did cause me some elbow pain. I ordered some memory foam for the arm rests.
Over all I like the chair. It is difficult to adjust the tension of the back of the chair and the arms to no go as low as I'd like. For so many adjustable functions it's a great price!
