Pressure-relief mattresses vary the pressure between a patient and the mattress. They use a combination of engineered foam and air cells to redistribute pressure and prevent the formation of bedsores and ulcers.
Friction and pressure cause bedsores in patients who don’t move for long periods. By continually adjusting and redistributing pressure, pressure-relief mattresses preclude the formation of ulcers, help existing ulcers to heal more quickly, and are more comfortable than standard mattresses.
