This wheelchair gel bladder encased cushions are made from unique pressure relieving material to provide a stable, pressure relieving sitting position. Due to the open cell, visco-elastic and temperature sensitive properties of the material, the Tempur wheelchair cushion fits the body-shape perfectly. The Tempur wheelchair cushion widens the pressure area and distributes pressure evenly along the entire surface area of the cushion. The Tempur wheelchair cushion relieves pressure on prominent body parts e.g. the coccyx and the projecting thighbone. The risk of developing pressure sores is greatly reduced, and the patient sits in a comfortable, stable and relaxed position.
