Alternating pressure therapy mattresses use pressure redistribution to stimulate blood flow and nourish the skin. The air cells of the mattress slowly inflate and deflate under the patient at a predetermined or adjustable cycle time. The process allows time for blood flow to reach the skin and provides healing of the skin breakdown or bedsores. The alternate pressure mattresses offer a comfortable and relaxing support surface that can prevent pressure injuries and enables a good night's sleep. Get the right mattress for the uninterrupted sleep and day long comfort of your loved ones. Select from the premuim brands: Span America, Roho, Proactive Medical, Invacare, and many more.
