Used once and then stored. I am also selling other round seat cushions. TITIROBA Round Seat Cushion, Postpartum Donut Cushion, Hemorrhoid Cushion, Round Seat, Donut-shaped Cushion, Donut Seat Cushion, Pregnant Women's Hole Cushion, High Resilience Cushion, Black Brand: TITIROBA Features: Washable Color: Black Size: Approximately 44 x 33 x 6.5cm Material: Polyurethane (PU) Shape: Round [Promotes pressure distribution with gel and high-resilience urethane material] The TITIROBA round seat cushion uses a high-resilience cushion material with moderate resilience that prevents the body from sinking too much, providing firm support for the buttocks and lower back. The gel material dissipates heat, making it comfortable to sit on. [Ergonomically designed to avoid putting pressure on the affected area] This donut cushion reduces pressure on the affected area, making sitting comfortable for postpartum women and those suffering from hemorrhoids, as the painful area does not come into contact with the ground. The indentation at the back prevents pressure from concentrating on the lower back, protecting the waist, and the indentation at the front does not compress the crotch area, distributing body pressure and allowing for relaxed sitting. [Just the right size] Not too hard and not too soft, it has a thickness of about 6.5cm and does not feel like you're sitting on the floor. It's a larger "Big Size" compared to other companies, providing a more comfortable fit. The right size and high-resilience material allow you to use it without worrying about stuffiness compared to general donut seat cushions. [Includes 1 removable, washable cover] The cover is washable, so it's always clean. The surface uses a skin-friendly fabric for a comfortable sitting experience. The back is non-slip for stable sitting. *Cover only washable. [For mothers suffering from postpartum pain and those suffering from hemorrhoid pain] Quality tested by a public inspection agency, so you can use it with peace of mind. Comes with a convenient carrying bag, making it easy to carry and perfect for presents. It's a great help as a postpartum cushion for women after childbirth and as a cushion for hemorrhoids.
