I'm a bit disappointed with this chair and not sure yet if I want to keep it. It's a nice size, and other reviewers were totally not lying about how firm the seat is. What disappoints me is that there is no actual seat mattress that you can remove. Everything is built into the chair and covered by one sheet of fabric. Had I know. That prior to purchasing the chair I may have ordered a different one. The other gripe I have is that the fabric on the chair is SUPER SCRATCHY. It looks soft and smooth in the picture but in real life it feels like burlap-rough and abrasive. I probably would not buy this chair again.
