I'm a 5'10" thin female. Bought this as a "go-between" my old ancient chair until I can afford the "cadillac." I've only used it a month but it seems just fine. I will sit at my desk for HOURS at a time and ... fatigue is fatigue but I'll keep this one for the time being. Of course it could have a few more adjustment controls but that's why THOSE chairs cost the big bucks.
