Ergonomic memory foam support for everyday sitting.
Most of us spend the better part of the day in a chair. The OrthoCore™ Seat Cushion is built around a contoured ergonomic profile that distributes your weight evenly and encourages a settled, upright seated position — so long hours at a desk or behind the wheel stay comfortable.
