This is a high-resilience round cushion. I purchased it after giving birth in December 2024, but when I tried sitting on it, the position of my wound was such that it caused more pain. I haven't used it since, so it's in excellent condition with no signs of use. It has a zipper, and the outer cover is washable. However, please understand that this is a used item stored at home. If you have any questions, please feel free to comment before purchasing. - Color: Navy - Shape: Round - Material: High-resilience - Zipper: Yes The purchase was made on Rakuten, and the product is as follows: 1st Place Winner 【5% OFF with LINE Add】 Round Cushion Postpartum Portable Hemorrhoids Firm Donut Cushion Donut-shaped Cushion High Resilience Maternity Cushion Pregnant Women Hole Cushion Cushion for Chairs Breathable [Rakuten] #Rakutenichiba https://item.rakuten.co.jp/high-high/cicushion04/?scid=wi_ich_iphoneapp_item_share Thank you for looking.
