Reversible mattress

Claim 2

A cushion assembly which can be reversed in orientation to expose support cushions having different stiffnesses, said cushion assembly comprising a stiffener member which includes (1) a plurality of section elements which are positioned in generally abutting side by side relationship to one another, each section element defining a first face, an oppositely directed second face, and side edges, each section member also including an abutment ridge which extends away from its second face adjacent each side edge thereof which is abuttable with the side edge of an adjacent section element, and (2) a hinge means connected between the first faces of adjacent section elements so as to flexibly connect said plurality of section elements together; said abutment ridges on said section elements being abuttable to prevent the movement of adjacent section elements such that their second faces pivot towards one another, and said hinge means connected between said section elements allowing adjacent section elements to move such that their first faces pivot toward one another, a first support cushion connected to said hinge means, said first support cushion having a unitary structure and a predetermined stiffness, and a second support cushion connected to the second faces of said plurality of section elements, said second support cushion having a unitary structure and a predetermined stiffness, the predetermined stiffness of said second support cushion being greater than the predetermined stiffness of said first support cushion.

Claim 3

The cushion assembly as defined in claim .[.1.]. .Iadd.13 .Iaddend.wherein said hinge means comprises a single piece of material which is connected to the first faces of said plurality of section elements.

Claim 4

The cushion assembly as defined in claim 2 wherein said material comprises cloth.

Claim 5

The cushion assembly as defined in claim 3 wherein said cloth includes fiberglass.

Claim 6

The cushion assembly as defined in claim .[.1.]. .Iadd.13 .Iaddend.wherein each of said plurality of section elements includes a plurality of perforations.

Claim 7

The cushion assembly as defined in claim .[.1.]. .Iadd.13 .Iaddend.wherein said first and second support cushions are generally rectangular in shape and have equivalent longitudinal and transverse dimensions, and wherein said stiffener member is generally rectangular in shape but has smaller longitudinal and transverse dimensions than said first and second support cushions so as to provide a recess between said first and second support cushions of uniform dimensions and in which the edges of covering sheets for the support cushions can be retained.

Claim 8

The cushion assembly as defined in claim 6 wherein at least one of said section elements is composed of at least two portions, and wherein each portion of each section elements is connected to adjacent portions by said hinge means.

Claim 9

The cushion assembly as defined in claim 7 wherein at least one of the section elements which are respectively located at the opposite ends of said plurality of section elements comprises at least three portions which are shaped so as to provide two separations that respectively extend diagonally inwardly from the corners thereof.

Claim 10

The cushion assembly as defined in claim .[.1.]. .Iadd.13 .Iaddend.wherein each of said first and second support cushions is made of foam rubber, the foam rubber of said second support cushion being denser than the foam rubber of said first support cushion.

Claim 11

The cushion assembly as defined in claim .[.1.]. .Iadd.13 .Iaddend.which further includes a separate rigid baseboard.

Claim 12

The cushion assembly as defined in claim 10 wherein said rigid baseboard includes perforations.

Claim 13

The cushion assembly as defined in claim 11 which consists of said stiffener member, said first and second support cushions and said rigid baseboard. .Iadd.

Claim 14

A cushion assembly which can be reversed in orientation to expose support cushions having different stiffnesses, said cushion assembly comprising a stiffener member which includes (1) a plurality of generally flat section elements which are positioned in generally abutting side-by-side relationship to one another, each section element defining a first face, an oppositely directed second face, and side edges, at least one of said side edges of each section element being adjacent a side edge of an adjacent section element, each section element also including an abutment ridge at each of said side edges thereof that are adjacent to a side edge of an adjacent section element, and (2) a hinge means connecting adjacent section elements such that, when the connected adjacent section elements are aligned in common plane, they can be pivoted towards one another in one direction but not in the opposite direction, a first support cushion having a unitary structure and a predetermined thickness, said first support cushion being connected to said section elements over the faces thereof which will move together when said connected adjacent section elements are aligned in a common plane and then pivoted towards one another, and a second support cushion having a unitary structure and a predetermined thickness connected to said section elements over the opposite faces thereof to which the first support cushion is connected, the predetermined stiffness of said second support cushion being greater than the predetermined stiffness of said first support cushion. .Iaddend.

Claim 15

A cushion assembly which can be reversed in orientation to expose support cushions having different stiffnesses, said cushion assembly comprising a stiffener member which includes (1) a plurality of generally flat section elements which are positioned in generally abutting side-by-side relationship to one another, each section element defining a first face, an oppositely directed second face, and side edges, at least one of said side edges of each section element being adjacent a side edge of an adjacent section element, each section element also including an abutment ridge at each of said side edges thereof that are adjacent to a side edge of an adjacent section element, and (2) a hinge means connecting adjacent section elements such that, when the connected adjacent section elements are aligned in common plane, they can be pivoted towards one another in one direction but not in the opposite direction, a first support cushion having a unitary structure and a predetermined thickness, said first support cushion being connected to said section elements over the faces thereof which will move together when said connected adjacent section elements are aligned in a common plane and then pivoted towards one another, and a second support cushion having a unitary structure and a predetermined thickness connected to said section elements over the opposite faces thereof to which the first support cushion is connected, the predetermined stiffness of said second support cushion being greater than the predetermined stiffness of said first support cushion. .Iaddend.
