ABSTRACT:
A low air loss mattress continuously supports a person lying thereon, and includes an upper layer of inflatable cells, and a separate lower layer of inflatable cells. The lower layer of inflatable cells is always maintained at a constant pressure which is higher than the pressure in the upper layer of cells to prevent a person lying on the mattress from contacting the underlying support surface, in particular, when sitting or during transport. Cells forming the upper layer may be inflated at different pressures to provide optimum support to different parts of the body.
