This chair is awesome! I got it for my Husband as his gaming chair, because the one he was using before offered no back support and I know it was uncomfortable for him. He absolutely loves this chair and one of the main bonuses is the massage function! A lot of people complained that it was merely just vibration, but it is enough to give him some relief after a long day! It fits him fine, he is 5'10" and has thick thighs and a donk but he is very comfortable in the size! Great chair!
