It was too big and I couldn't use it at all, so I kept it in a plastic bag on a shelf. (The bag came with another large cushion I bought.) Large round cushion Diameter 55cm x Height 20cm It can be used as a pillow, a body pillow, or even as a floor cushion because it's thick and firm. Purchased in Jiyugaoka. ♦︎ Non-smoking, no pets, stored in a room with controlled humidity and temperature.
