ABSTRACT:
A cushion or pad comprises a first layer of a first synthetic cellular material having a first average cell volume and a second layer of a second synthetic cellular material having a second average cell volume at least ten times greater than the first average cell volume. The first layer is attached to the second layer so that the first layer and the second layer at least partially overlap one another to form a multilayer structure. The layer with the larger average cell volume is a polymeric sheet with at least a substantially planar array of fluid-filled pockets or chambers. The layer with the smaller average cell volume is a foam material with either open cells or closed cells. Further layers of fluid-filled chambers or foam material may be attached to the first two layers.
