The All Day Gel Seat--18".
This gel seat cushion relieves point-of-contact pressure and helps reduce lower back pain inherent in long periods of sitting in a car or office chair. The cushion is filled with a soft visco-elastic gel and supportive memory foam that disperse your weight to alleviate pressure points. The surface has a subtle 5-degree slope that promotes proper pelvic posture, encouraging correct lumbar curvature. A depression in the center of the cushion eliminates contact pressure on the tailbone and soft tissue, and 10 small perforations provide ventilation. The cushion folds in half and has an integrated handle to enable simple transport.
