摘要

The device has inflatable cushions (1) pneumatically inflated together and separated by an electric air pump (2), and solenoid valves (4) fixed on an air distributer (3). A control unit (5) i.e. control board, controls simultaneous or independent inflation of the inflatable cushions by a wave or an infra-red radiation. The device is dimensioned such that dimensions of the mattress are approximately 25 cm to make slipping of a bedding under the mattress. Two side rolls are respectively arranged at a bottom part and a top part of a bed.
