It has good support for Your back but the screw covers won't stay on! I don't want to have to glue them on. Just keep having to put them back on and I shouldn't have to keep doing that! Or I would have given it a 5 because of that I give it a 4.
Overall the chair is comfortable but I find myself wanting the the seat to be "deeper"; I feel that I'm being pushed slightly forward when I sit. There is no lumbar or seat back adjustment to make with this chair. Also the seat cushion could be firmer.
The most recent office chair I had was not one that I really liked but got a "good deal" on it. This chair however is awesome! Very comfortable and definitely worth the $
