Ergonomic Seat Cushion for Office Home Car

The Kensington K55805WW is an ergonomic memory foam seat cushion designed for anyone who sits for long periods at a desk, in a vehicle or at events. It promotes healthy posture and improves circulation while reducing discomfort, fatigue and stiffness in the tailbone and lower back.
