The surface of our portable gel cushion for chairs is gently sloped to keep your lumbar in the correct position to help prevent and reduce lower back pain. The surface is also pressure-distributing and ventilated for proper air circulation. Carry it anywhere with you by folding it in half and using the attached handles. 18 3/4" W x 16 1/2" D x 1 1/4" H.
