1 H x 16 W x 13 1/2 D.
Portable Gel Seat (2 1/2 lbs.) The surface slopes forward a gentle 5u00B0 to encourage proper pelvic posture for correct lumbar curvature, while 16 small vented openings allow for adequate ventilation. Unlike bulky seat cushions that are heavy or difficult to carry, this compact gel-filled cushion weighs only 2 1/2 lbs, folds in half, and is easily portable due to its integrated handle.
