Abstract
In this study was investigated how to enlarge the contact area of the body surface in order to improve the body pressure dispersion performance in the mattress. We have developed a mattress, by controlling the shape and the fixed and the pressure of the air cell can be deformed to the same pair surface shape, and air cells is along the body surface shape, and can be supported in a distributed weight. As a result was shown in figure. For mattress was placed on the surface of the air cells, a decrease in body pressure was observed by controlling the air cells. It is not to centrally the body pressure in the bone protrusion in dorsal position.
