A cushion includes a cushion shell formed to define a fill receiving cavity and a cushion fill that resides within the fill receiving cavity. The cushion shell includes a shell upper surface, at least one shell side surface and a bottom surface. The shell upper surface is generally oriented parallel to a first plane. The shell upper surface does not include any seams and is fabricated from at least one water impervious material. The at least one shell side surface is generally oriented parallel to a second plane perpendicular to the first plane. The shell side surface is fabricated from the at least one water impervious material. The shell bottom surface is generally oriented parallel to the first plane. The shell bottom surface is fabricated from a water pervious material and is joined to the side surface along a bottom edge seam.
A sub-assembly is disclosed. The sub-assembly is a valve including: a housing, a plunger, a seal, an indexing member, a biasing member, a seat member and a push button actuator. The plunger axially supports the seal and the indexing member within the housing. The biasing member is supported by the seat member and axially biases the plunger relative the housing in a first axial direction in order to axially bias the seal in the first axial direction toward a sealing surface formed by the housing. Arrangement of the seal adjacent the sealing surface formed by the housing prevents fluid flow through the valve. When the seal is arranged adjacent the sealing surface formed by the housing, a distal camming surface of the indexing member is not registered adjacent a corresponding camming surface of the housing. The push button actuator is arranged for movement relative the housing in a second axial direction that is opposite the first axial direction such that movement of the push button actuator relative the housing in the second axial direction results in a corresponding movement imparted to the plunger in the second axial direction. Movement of the plunger in the second axial direction results in corresponding axial movement of the seal in the second axial direction such that the seal is axially moved away from the sealing surface formed by the housing to thereby permit fluid flow through the valve. A self-inflating assembly is also disclosed. A cushion assembly is also disclosed. A method is also disclosed.

A process for manufacturing a polymer fill, the method comprising the steps of blending polymer fibers to form a polymer fill, depositing the polymer fill onto a surface, orientating the polymer fibers in a desired orientation, heating the polymer fill, compressing the polymer fill and cooling the polymer fill. The surface carries the polymer fill from the blending step through the heating step, and wherein the polymer fill enters the compression step independent of the surface.
