ROHO is a well-known brand of quality medical air cushions. A ROHO cushion is made up of inflatable air cells that evenly distribute the user's weight across the surface of the cushion. The sizes of the air cells are different in various areas of the cushion. This keeps too much weight from being applied on a single area of the body, preventing pressure sores and skin damage. These air cushions are made of neoprene rubber that is easy to clean and repair. Along with their wheelchair cushions, ROHO also makes mattress overlays, commode cushions, and air cushion accessories.
