PURPOSE: An air compression bed uniting a plurality of syringe pistons is provided to protect a back and other organs on a bed by accompanying variation of volume with pressure. CONSTITUTION: An air compression bed uniting a plurality of syringe pistons is a variable bed apparatus of which volume varies according to a compression degree of air. The bed controls size and number of the piston. The air compression bed uniting a plurality of syringe pistons differentially or identically inject air. The number of pistons is to be more than 30 so that air compression according to variation is performed and the size of piston is not restricted. Continuous supply of air and resupply of air should be required to prepare for loss of the air.
