Abstract
Cushions are disclosed herein. In one embodiment, a cushion is comprised of a plurality of foam profiles each having a top surface and a bottom surface, and a geometry of reduced cross-section area from the top surface to the bottom surface in a vertical projection. The plurality of foam profiles are arranged such that the top surfaces of the plurality of foam profiles are disposed in or substantially in a first plane. In this manner, hollow portions can be formed between adjacent foam profiles. At least one sheet of material is affixed to at least one of the top surface and the bottom surface of the plurality of foam profiles. When a compression force is imposed on the cushion, the hollow portions allow the foam profiles to adapt to deformation. Further, by providing the hollow portions, the cushion can more easily be rolled or wrapped for transport or storage.
