VISCO-ELASTIC BODY SUPPORT AND METHOD OF MANUFACTURING THE SAME
A pillow assembly including a foam core having a top surface, side surface, and bottom surface, and an outer layer covering the top surface and side surface and leaving the bottom surface substantially exposed. The foam core has a higher hardness and a higher density than the outer layer. The foam core and the outer layer comprise reticulated or non-reticulated visco-elastic foam. The outer layer covers a majority of the foam core and has a substantially constant thickness across the top surface. The foam core includes a front side and a back side, both of which are covered by the outer layer and left and right sides of the foam core, which are exposed.
