Abstract
A pad for supporting a portion of the human body is made of two substantially non-stretchable or non-elastic layers that are joined together along a peripheral edge and then are joined together in local regions to form individual capsules in the pad. The layers are “quilted” in the areas defined by the capsules to control where and how much the pad can bulge. The pad is filled with a wax material that is plastic but does not flow readily. By repeated applications of loads the wax will flow or migrate slowly to change the configuration of the wax to conform to and support the surface contacting the pad.
