Collapsible layered cushion
First Claim
1. A layered cushion comprising:
- a first matrix of void cells formed exclusively in a first sheet of resiliently deflectable material, the first matrix including at least two rows and two columns of void cells;
a second matrix of void cells formed exclusively in a second sheet of resiliently deflectable material, the second matrix including at least two rows and two columns of void cells, wherein each void cell of the first matrix is axially aligned with a corresponding void cell of the second matrix;
a plurality of drainage holes providing one or more fluid-permeable channels through the first sheet of resiliently deflectable material and the second sheet of resiliently deflectable material;
a foam layer; and
a removable cover configured to envelop the first matrix of void cells, the second matrix of void cells, and the foam layer, wherein the foam layer is removable from the cover, the first matrix of void cells, and the second matrix of void cells.

Abstract
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.

9. A washable layered mattress comprising:
-
a foam layer; a void cell layer including a first matrix of void cells formed exclusively in a first sheet of resiliently deflectable material and a second matrix of void cells formed exclusively in a second sheet of resiliently deflectable material, wherein the first matrix includes at least two rows and two columns of void cells and the second matrix includes at least two rows and two columns of void cells; 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; a plurality of drainage holes providing one or more fluid-permeable channels through the first sheet of resiliently deflectable material and the second sheet of resiliently deflectable material of the void cell layer; and a removable cover configured to envelop the foam layer, the separation layer, and the void cell layer. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A method of assembling a layered cushion comprising:
-
positioning a foam layer adjacent to a void cell layer on opposite sides of a separation layer, wherein the separation layer contacts the first matrix of void cells and substantially prevents the foam layer from collapsing into the void cell layer, the void cell layer including a first matrix of void cells formed exclusively in a first sheet of resiliently deflectable material and a second matrix of void cells formed exclusively in a second sheet of resiliently deflectable material, wherein each void cell of the first matrix is aligned with a corresponding void cell of the second matrix and includes a drainage hole that facilitates fluid transport through the first sheet of resiliently deflectable material and the second sheet of resiliently deflectable material, and wherein the first matrix includes at least two rows and two columns of void cells and the second matrix includes at least two rows and two columns of void cells; positioning the foam layer and the void cell layer within a cover; and closing the cover to envelop the foam layer and the void cell layer, wherein the foam layer, the void cell layer, and the cover are removable from one another. - View Dependent Claims (18, 19, 20)

21. A washable layered mattress comprising:
-
a foam layer; a void cell layer including a first matrix of void cells formed exclusively in a first sheet of resiliently deflectable material and a second matrix of void cells formed exclusively in a second sheet of resiliently deflectable material, wherein the first matrix includes at least two rows and two columns of void cells and the second matrix includes at least two rows and two columns of void cells, wherein each of the void cells in the first matrix and in the second matrix is maintained at atmospheric pressure independent from a state of compression of the void cell layer; a separation layer configured to be oriented between the foam layer and the void cell layer, wherein the separation layer substantially prevents the foam layer from collapsing into the void cell layer; and a removable cover configured to envelop the foam layer and the void cell layer wherein the foam layer is removable from the cover, the first matrix of void cells, and the second matrix of void cells.
