Chikawa Usagi Morishita This is a round, cooling, low-rebound cushion. It's reversible with different materials, so I think you can use it regardless of the season. It's a USED item, but I don't see any stains or scratches on the main body. The tag shows some signs of use. Please refrain from purchasing if you are concerned about minor details. [Product Description] ● The surface is made of microfiber fabric for a gentle touch. ● The back side has a different pattern and a cool-to-the-touch, cooling material. ● Approximately 40cm in diameter, it fits perfectly on adult chairs. ● Low-rebound material gently and firmly supports your hips and lower back. ● Perfect for the living room, car, desk work, or studying.
