Abstract: A cushion for supporting a user relative to a support surface is provided. The cushion has material with sufficient flexibility to deform under a weight of the user and sufficient resilience to return to its original state when the weight is removed. A supporting face contacts the support surface and is characterized by a plurality of points. The supporting face is contoured such that, when the cushion is in an unloaded configuration, a first subset of the plurality of points contact the support surface and a second subset of the plurality of points do not contact the support surface. When a user then sits on the cushion so that it is in a loaded configuration, at least some of the points in the second subset are displaced under the user's weight and contact the support surface. The cushion thus both bends and compresses to distribute the weight of the user.

Abstract: A cushioning device for supporting a user in seated or recumbent posture, e.g., in a wheelchair, comprises a resiliently compressible foam base layer with an upper surface formed of a configuration generally conforming to the user's body and defining a fluid drainage path to a fluid drainage and collection area in case of incontinence episodes, an absorbent layer disposed in association with the fluid collection area for collection and holding fluids draining to the collection area, a fluid-impermeable bottom layer covering the underside of the base layer, and a non-absorbent top layer covering the upper surface of the base layer. Together, the fluid permeability and non-absorbent character of the top layer and the compressible resiliency and drainage configuration of the foam base layer for draining fluids to the absorbent layer, mitigate pressure, heat, moisture, shear and friction conditions that are the main contributing causes to formation of decubitus ulcers.
