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 void cell layer including at least a first matrix of void cells formed exclusively in a single sheet of resiliently deflectable material; a foam layer; a separation layer interleaved between the foam layer and the void cell layer and in contact with the first matrix of void cells, the separation layer substantially preventing the foam layer from collapsing into the void cell layer; and a cover configured to envelop the void cell layer, the foam layer, and the separation layer.
