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.
