About this item Memory Foam Seat Cushion: The donut-shaped cushion is made of high-quality rebound foam. The cushion slowly rebounds after each use, maintaining its shape. The cover of the orthopedic seat ring is velour, soft and comfortable, removable, and machine washable. Seat Cushion with Hole: Thanks to its ergonomic O-shaped design, the donut seat cushion adapts to your body's pressure points. The hollow design reduces direct contact with the seat surface, supporting pressure on the hips and waist and relieving tailbone and hip pain. .
