Approximately 42×40cm + 8cm fringe This is a thick, carpet-like cushion. I used it for sitting in a warehouse for about two years. I didn't sit on it for long periods, and food, drinks, and water were strictly prohibited. Also, children and cats were generally not allowed in the area, so there are no noticeable scratches or stains. If you'd like, please consider it for your office chair, or as a mat for your dogs or cats.
