I'm selling this because I bought it but haven't had a chance to use it. The following is an excerpt: High-rebound cushion that won't sink even when an adult sits on it! Made with expanded polyethylene, it won't lose its shape even after sitting for long periods, and it's strong enough to be used as a step stool, with a firmness that won't sink even when an adult stands on it. - 17cm thick, making it easy to sit and stand, and weighs only 635g! - The cover has a handle, which is very convenient for moving it. - The cover is hand-washable, so you can keep it clean. - The design is unobtrusive, so you can leave it out, and it saves space when not in use by standing it up. It's a multi-functional cushion that can be used as a chair, combined to stretch out your legs, or as an accent color in your room. [Size] Approximately 38cm x 38cm x 17cm [Color] Beige [Weight] Approximately 635g [Material] Cover: Cotton linen, Filling: EPE
