by Michael F, California, Oct 26, 2015
This chair comes with 100% polyurethane foam in the seat, and as such does not require any extra padding. It is so comfortable, and holds firm through long hours of use. I got mine with memosoft arms, which is the best way to go if you do lots of typing. The back is a mesh screen held in place by a plastic frame. The mesh is very comfortable and breathes nice on hot days. My one complaint is that the frame on the edges of the back is hard, so you have to make sure to only sit with you back in the center of the chair. That said, it does force you to maintain good posture, so I think this is a pretty minor complaint. Overall a great chair!
