It’s an integrated cushion and washable custom cover: Matrix’s surface module cushions (pads) spread pressure evenly to allow for excellent airflow and to significantly decrease moisture and heat retention. The thermo-elastic polymer cushion is designed to provide superior pressure relief and shear reduction. A washable, padded cover is available; it secures in place and does not shift around complex curves, yet can be easily removed for cleaning. Grows and adjusts per the client’s needs.
