The Masonair™ LS9000B Bariatric low air loss with alternating pressure mattress is the most advanced system in the Masonair™ series. The high flow multi function air control unit will support up to 1000lbs. The microprocessor sensor technology provides continuous feedback to equalize pressure and maximize patient comfort. The mattress consists of (20 interchangeable) 10” high air cells, encapsulated by a removable waterproof zippered quilted top cover. The top cover is fire retardant, non shear, low friction, anti-microbial and anti-bacterial. In case of a power failure, the patented cell-in-cell design allows the inner cells to remain inflated via a one way valve.
