This is a thin, compact, low-rebound cushion with a mesh fabric back support. It has a belt to secure it to chairs, etc. The cover has a zipper and can be removed. Width: 36cm Height: 32cm It's compact, so it can be carried around and used. There is a slight mesh disturbance in one place, but it's barely noticeable. Please check the photos. No smokers, no pets. Used 1-2 times and in good condition, but it has been stored at home, so please understand that it is a used item. Thank you.
