Extra-Large TravelMate Seat Cushion with Specially Designed Non-Slip Cover to Prevent it from Sliding Even on Polished Marble Floor (Size: 19 x 17 x 3 inches)

New! This extra-large seat cushion is constructed of a highly resilient, furniture-graded foam with a layer of high density memory foam on top. This unique design combines the two key elements you are looking for: comfort and durability. Its extra size enables it to provide bigger coverage to dissipate pressure more effectively while conforming to body contours. It is firm enough to give you good support but not to the point of being "too hard" to undermine its use as a cushion. It can be used in the car, home, or office. It is designed to help relieve back pain, numb buttocks, and other discomfort associated with prolonged sitting. What you get is a high quality product for a lot less than what you have to pay at specialty stores. This newly released and improved version includes a high quality cover coated with a non-slip silicone layer at the bottom of the cushion to prevent it from sliding even on polished marble floors.
