A unique combination of air and gel technology that provides effective pressure relief and comfort to the high risk user. The cushion has 34 interconnected air-filled cells, each covered with a layer of pressure relieving silicone-based Trugel. As pressure is applied, air circulates to each cell, distributing weight evenly, thus reducing high pressure concentrations around lean prominences. The cushion can be quickly and easily adjusted to suit the comfort of the user. Covered in a stretchy and breathable material with anti-slip base reduces the effects of shear and helps support good posture. Easy to clean and maintain. Length 425mm (17"). Width 425mm (17").
