Chair has good support and features you would expect for a chair in this price range. I won it in a raffle which makes it even more wonderful! I would really rate the chair a 4.5 with the only drawback being the arm rests. There fixed molded plastic/rubber composite like materials with an indentation for your arms to fit in. If you type with your elbows out away from your body or your keyboard is ergonomically designed, so that your arms are on an angle, the armrests can be uncomfortable
