Floatation-type mattress filled with fluidized balls

Abstract

Provided is a floatation-type mattress filled with fluidized balls, wherein: a tunnel is fully filled with balls along the periphery of the mattress body; a container is merged and connected with a lower plate made of a stiff mesh and an upper plate made of a flexible mesh; multiple columns are arranged inside the container and configured to be pressed vertically; the container is filled with lightweight fluidized small balls; and dynamic equilibrium according to Pascal's principle evenly distributes weight such that, regardless of the angle of bent surfaces of the human body, weight is evenly distributed over all body connection surfaces, thereby providing equilibrium. The floatation-type mattress comforts a person as if he/she is floating on the Dead Sea, has good ventilation, and can be used in a bedroom. The floatation-type mattress prevents or alleviates pressure ulcers occurring to a person restricted to lying in bed for a long period of time.
