A Bigger, Thicker Gel Seat Cushion

If your seat cushion feels too small, too thin, or starts flattening after months of sitting on it, upgrading to another ordinary foam cushion may not solve the problem. The CellGel+ Grand Ultimate Seat Cushion gives you a massive 20" × 20" sitting surface and 2.4" of responsive CellGel+ cushioning underneath you. That extra size gives you more room to sit and more coverage across your chair, while the flexible honeycomb gel grid spreads pressure across the cushion instead of concentrating it in a few areas. And unlike traditional foam, CellGel+ is designed to flex and spring back into shape after you stand up. Hundreds of open-air channels also allow heat to escape through the cushion while you sit, helping you stay more comfortable during long days at your desk, long drives, meals, gaming, or anywhere else you spend hours sitting. ✓ Oversized 20" × 20" sitting surface ✓ Extra-thick 2.4" CellGel+ grid ✓ More room and cushioning underneath you ✓ Responsive pressure-distributing design ✓ Open honeycomb grid for better airflow ✓ Designed to return to shape after use ✓ Non-slip removable cover ✓ Washable cover and gel grid If ordinary seat cushions have always felt a little too small or insubstantial, Grand Ultimate was built to give you a lot more cushion to sit on.
