The present invention is directed to a cushioning device. The cushioning device has a flexible container and a plurality of polymeric beads within the flexible container which flows under a slight force and shears easily. The cushioning device is capable of receiving a physical object that applies a force to the cushion. When the force is initially applied to the cushioning device, the cushioning device is deformed to conform to the physical object from its original shape. When the physical object is not applying the force, the cushioning device reverts to a shape that is close to but not identical to the original shape, except for a limited number of materials such as molded elastomeric materials. In addition, the pressure exerted by the cushion on the physical object will reduce pressure that would cause tissue damage and lead to decubitus ulcers.
