Thank you for viewing. [Product Details] This is a donut-shaped cushion made of urethane foam. It's thick and has a bouncy resilience, making it recommended for before and after childbirth. [Condition] I bought it before giving birth, but I only tried sitting on it a few times before delivery, and I haven't used it at all after. It's in near-new condition with no stains or wear, and has been stored at home. [Other] The diameter is 35cm and the height is about 6-7cm. Please purchase only if you understand that this is a used item. Color...Gray系 (Gray-ish) Stains, tears, odors, etc...None
