Abstract
A decubitus mattress includes an inflatable cell surrounded by foam with a built-in low-voltage (AC) air pump assembly for controlling the air cell's inflation. In some embodiments, a mattress includes a plurality of inflatable cells, one or more of which (particularly at the foot end of the mattress) can be selectively deflated with valves that are located along the side of the mattress, in corresponding positions.
