Pressure reducing support surfaces are a type of medical equipment used for the care of pressure sores, also known as pressure ulcers or injuries. Pressure ulcers are lesions caused by constant pressure on areas in contact with the mattress, resulting in damage of skin and deep tissues.

Some pressure reducing mattresses are powered by electricity and others, like the non-powered advanced pressure reducing mattresses, are not. They replace a standard hospital or home mattress and are placed on a hospital bed frame. Non-powered advanced pressure reducing mattresses have a surface designed to reduce friction and shear, and are made of foam, air, gel and other materials. They are indicated for persons with deeper pressure ulcers (stage II, III or IV) or after surgery, for persons who received a flap or skin graft to cover a wound. 

Powered pressure-reducing air mattresses can be rented through Medicare from medical equipment stores. You can also purchase this product "out-of-pocket" (without insurance), from medical equipment stores.
