The Drive Medical Swivel Seat Cushion is compact in size and supports up to 350 pounds. Perfect for use in your car, van, truck, office, or home. It turns a full 360 degrees, minimizing stress on the back, hips, or knees associated with twisting and turning to get out of a seat. The seat cushion's foam padding is soft and comfortable, helping to reduce the pressure on the back and tailbone, especially when seated for long periods. The height of this cushion also makes the road more visible, while the compact size is perfect for using in deep bucket seats, scooters, or smaller chairs. The removable cover is machine washable, making clean-up a snap. Backed by a limited one-year warranty from Drive Medical, a leading brand of mobility aids and other medical goods for more than 20 years, you can purchase with confidence.
