Abstract

A composite mattress includes a pressurizable layer and a top layer. A coiled spring layer may also be included in the composite mattress. The composite mattress may also include a base layer and/or an intermediate layer. A foundation, or rail, may laterally surround the pressurizable layer and the top layer. The composite mattress may include a cover, including a base panel, a periphery, and a top panel. The cover may encase the other components of the composite mattress. The composite mattress may include a separable top and bottom; these elements may be modular, enabling individuals or couples to customize a mattress by selecting one or more tops from a plurality of available tops for use with one or more bases from a plurality of available bases.

First claim

What is claimed:

1. A mattress, comprising:
a coiled spring layer;
a pressurizable layer; and
a top layer over the coiled spring layer and the pressurizable layer and comprising a plurality of compressible walls defining an array of buckling columns.

2. The mattress of claim 1 , further comprising:
a foundation including at least one peripheral foundation member defining a foundation receptacle.

3. The mattress of claim 2 , wherein the coiled spring layer is located within the foundation receptacle.

4. The mattress of claim 3 , wherein the pressurizable layer is located within the foundation receptacle.

5. The mattress of claim 1 , further comprising:
an intermediate layer on the pressurizable layer, the top layer being located on the intermediate layer.

6. The mattress of claim 1 , further comprising:
a bottom cover including a cover base with a peripheral edge;
a cover periphery extending from the peripheral edge of the bottom cover, with a cover receptacle being defined by the cover periphery and the cover base, the cover receptacle receiving the coiled spring layer; and
a top cover over the top layer.

7. The mattress of claim 6 , wherein at least a portion of the cover periphery is continuous with the cover base and further comprising:
a coupler at or adjacent to a top edge of the cover periphery, the coupler coupling the top cover to the cover periphery.

8. The mattress of claim 1 , wherein the pressurizable layer is located over the coiled spring layer.

9. The mattress of claim 1 , wherein the pressurizable layer comprises a plurality of air chambers.

10. The mattress of claim 9 , wherein the plurality of air chambers are independently pressurizable.

11. The mattress of claim 9 , further comprising:
a pressure sensor associated with the top layer.

12. The mattress of claim 9 , further comprising:
a web of elastomeric material defining a structured grid defining a plurality of polygonal openings superimposed with the top layer.

13. A cushion, comprising:
a pressurizable layer; and
a cushioning layer over the pressurizable layer and comprising a plurality of compressible walls defining an array of buckling columns to support at least part of an individual's body, a contour of the cushioning layer definable by pressurization of the pressurizable layer.

14. The cushion of claim 13 , wherein the pressurizable layer comprises a plurality of air chambers.

15. The cushion of claim 14 , wherein the plurality of air chambers comprises a plurality of independently pressurizable air chambers.

16. The mattress of claim 13 , further comprising:
a pressure sensor associated with the cushioning layer.

17. A cushioning method, comprising:
positioning at least part of an individual's body on a cushioning layer comprising a plurality of compressible walls defining an array of buckling columns to support at least the part of the individual's body; and
pressurizing at least one air chamber to define a contour of the cushioning layer.

18. The cushioning method of claim 17 , wherein pressurizing at least one air chamber comprises individually pressurizing at least one air chamber of a plurality of air chambers.

19. The cushioning method of claim 17 , further comprising:
adjusting pressure within the at least one air chamber after positioning at least part of the individual's body on the cushioning layer.

20. The cushioning method of claim 19 , wherein adjusting pressure comprises adjusting pressure in accordance with a program.
