The mattress utilizes 18 independent 9" deep air cells to provide proper pressure redistribution for the prevention and treatment of Stages I-IV pressure ulcers. Lateral Rotation Therapy reduces the risk of pulmonary complications for patients who are immobile. A full, left or right turn mode is offered with either a 25 small turn or a 40 big turn. The mattress replacement is designed to fit all standard hospital beds and includes a high density foam base, head bolster and abduction wedge for additional patient safety. Supports patients weighing from 650 lbs. to 1000 lbs. Meets California Technical Bulletin #117 for fire retardancy. An optional fire barrier is available to meet the most stringent fire safety requirements when requested for foam base.
