I got this chair because 1. my back had been hurting a lot lately when I stand for too long, and 2. my colleagues have very good persuasion skills! It hurt for the first 2/3 days sitting in this chair because my body was too used to sitting in a weird position. It's all because this chair forces you sit like a normal person who doesn't want to have back problems at 35.
It's comfortable and has a lot features that you would otherwise not get in other chairs. The back support is great even when you lean back. It looks great with my desk setup as well.
I would've preferred the headrest to move towards my head as in its current position, I have to let my head go all the way back (and eventually sleep, my manager will understand).
Great chair and I'd recommend it for anyone who wants to sit comfortably and not worry about having back problems for a lifetime.
