Claim:
A head restraint, comprising: a first core portion including an exterior surface, an interior and a perimeter edge between the exterior surface and the interior; a first outer layer provided about at least a region of said exterior surface of said first core portion; a second core portion including an exterior surface, an interior and a perimeter edge between the exterior surface and the interior; and a second outer layer provided about at least a region of said exterior surface of said second core portion, wherein material defining at least a region of the perimeter edge of the first core portion is directly attached to material defining at least a region of the perimeter edge of the second core portion, wherein an edge of the first outer layer is directly attached to an edge of the second outer layer to define a perimeter seam therebetween, wherein the first outer layer is a cover wrapped around the perimeter edge of the first core portion and toward the interior of the first core portion, and wherein the second outer layer is a cover wrapped around the perimeter edge of the second core portion and toward the interior of the second core portion such that the perimeter seam is defined between the first outer layer and the second outer layer, and further wherein the perimeter edge of the first core portion is bonded to the perimeter edge of the second core portion, and even further wherein the first and second core portions define a unitary structure formed entirely of expanded polypropylene; wherein the first core portion includes a secondary edge disposed radially inward from said perimeter edge of the first core portion to define an opening, and wherein the second core portion includes a secondary edge disposed radially inward from said perimeter edge of the second core portion to define an opening, and further wherein the opening of the first core portion and the opening of the second core portion are aligned to define an opening through the head restraint, and still further wherein at least a region of the secondary edge of the first core portion and the secondary edge of the second portion define a secondary seam.
