Collapsible layered cushion

摘要

A layered cushion that may be fully disassembled for easy cleaning is disclosed herein. The sleep system is durable and fire retardant. The layered cushion may include a foam layer, a layer of void cells, and a cover. The foam permits fluids to move freely there through and contours to a user's body to maximize comfort and reduce interface pressure. The reticulated foam layer resists compression set and thermosetting. The layer of void cells also permits fluids to move freely there through and provide additional support to the user's body. The individual void cells of the void cell layer are perforated to allow the transmission of fluids there through. The cover couples the other layers together to form the layered cushion and prevents the layers from deteriorating. The cover is removable to permit cleaning each of the layers independently.

主权项

1. A layered cushion comprising:
a foam layer; a fluid permeable void cell layer including:
a first matrix of void cells formed in a first surface;a second matrix of void cells formed in a second surface, wherein the first surface, the second surface, and the foam layer each share a common normal axis;at least one drainage hole at an interface between two adjacent void cells in the void cell layer, wherein the foam layer substantially collapses at a lower pressure than the fluid permeable void cell layer; a separation layer configured to be oriented between the foam layer and the fluid permeable void cell layer, wherein at least one void cell of the fluid permeable void cell layer opens to the separation layer; a rigid layer oriented adjacent to the fluid permeable void cell layer; and a cover configured to envelop the foam layer and the void cell layer, wherein the cover constrains the foam layer and the fluid permeable void cell layer in a selected position and orientation when enveloping the foam layer and the fluid permeable void cell layer, and wherein the foam layer, the fluid permeable void cell layer, and the cover are removable from one another.
