This desk chair is great for comfort and ergonomics. I have been using it for 2 years now and love it. The mesh seat and back has been especially important to me because the chair does not get sweaty or hot.
Chair is comfortable for multi hour use and stays nice and cool. My only real complaint is that the head rest doesn't move up or down only the tilt changes. I am 6'1" and the head rest sits at my shoulders when tilted all the way up. Removing that it is a great chair.
Since working remotely at home for the past year I suddenly started having coccyx pain. I tried all the recommended seat cushions for this issue but none helped. I decided I probably needed a new desk chair. I read a lot of reviews for great desk chairs but I need to try them out before buying. I tested this chair in a store and it was so comfortable that I immediately went home and ordered it. I have no regrets. It is so comfortable I don't have coccyx pain any longer. I love the head rest and how it reclines back. Highly recommend.
