Abstract:
1. A seat assembly comprising: a cushion composite having a structural layer comprising expanded polypropylene and a cushion layer comprising a polymer and disposed adjacent to the structural layer; and a trim material secured over the cushion composite; wherein a surface of the structural layer defines a first cavity extending laterally across the structural layer, a second cavity extending substantially transverse to the first cavity such that the second cavity extends from an end of the structural layer toward the first cavity, and a third cavity extending substantially transverse to the first cavity such that the third cavity extends from the end of the structural layer toward the first cavity and substantially parallel to the second cavity; wherein the second and third cavities are spaced apart from each other and spaced apart from the first cavity; and wherein the first cavity, the second cavity and the third cavity are configured to facilitate flexure of the structural layer when a force is applied to the structural layer.
