All-day pressure relief for coccyx and tailbone - The flexible honeycomb gel grid spreads your weight evenly to ease pressure on the hips, sitting bones and tailbone, so long hours at a desk, in the car or a wheelchair feel kinder on your body. Cooler than memory foam - Unlike foam that traps heat and slowly goes flat, Sitwell's open honeycomb gel lets air flow straight through, so you stay cooler and drier through long sitting at work, while gaming, or driving on warm days. Firm yet comfortable support - Sitwell is made to feel supportive without feeling hard. The gel gives just enough to cushion your sitting bones while holding its shape, so you are not perched on a stiff chair or sinking into soft foam. Washable cover included, and it stays put - Sitwell comes with a removable, machine-washable cover that many bare gel cushions leave out, and the non-slip base keeps it steady on office chairs, dining chairs, wheelchairs and car seats. One cushion for office, car, wheelchair and more - Use it for desk work, driving, gaming, travel and everyday mobility support. The neutral grey suits most chairs, it is light to carry between rooms or to the car, and the cover washes clean.
