Even though our bodies are designed to sitcomplete with strategically placed padding, it simply is not enough. Good thing we have a large selection of seat and back cushions for just about every sitting situation from the car to wheelchair, and desk to park bench. This cushion series has a gel/foam combination that provides pressure relief, prevents minor skin irritations, and improves weight distribution. It has a removable, machine washable polyester/cotton cover and a non-skid bottom with Velcro straps, which secure the cushion to the wheelchair. This 3 inch Gel/Foam combination cushion provides the user excellent weight distribution and even pressure relief. Non-flammable, cover is washable. Great for wheelchairs transpsort chairs or home and office.
