Claim 1
Independent Claim
63 words
A cushion, comprising an aggregate of individual non-cylindrical padding elements contained within a casing, each padding element consisting of a core and an outer layer surrounding said core, wherein the material of said core is different than that of said outer layer, and wherein said outer layer is formed of a resilient material having sufficient thickness to impart resiliency to said outer layer.
Claim 2
Dependent Claim
63 words
A cushion, comprising an aggregate of individual non-cylindrical padding elements contained within a casing, each padding element consisting of a core and an outer layer surrounding said core, wherein the material of said core is different than that of said outer layer, and wherein said outer layer is formed of a resilient material having sufficient thickness to impart resiliency to said outer layer.
Claim 3
Dependent Claim
26 words
A cushion as defined in claim 1 wherein the material of said cores is selected from a group consisting of wood, ceramics, metal rubber, or plastics.
Claim 4
Dependent Claim
24 words

Claim 6
Dependent Claim
63 words
A cushion, comprising an aggregate of individual non-elongated padding elements contained within a casing, each padding element consisting of a core and an outer layer surrounding said core, wherein the material of said core is different than that of said outer layer, and wherein said outer layer is formed of a resilient material having sufficient thickness to impart resiliency to said outer layer.
Claim 7
Dependent Claim
63 words
A cushion, comprising an aggregate of individual non-elongated padding elements contained within a casing, each padding element consisting of a core and an outer layer surrounding said core, wherein the material of said core is different than that of said outer layer, and wherein said outer layer is formed of a resilient material having sufficient thickness to impart resiliency to said outer layer.
Claim 8
Dependent Claim
68 words
A cushion, comprising an aggregate of individual padding elements contained within a casing, each padding element consisting of a core in the shape of a sphere, and an outer layer surrounding said core, wherein the material of said core is different than that of said outer layer, and wherein said outer layer is formed of a resilient material having sufficient thickness to impart resiliency to said outer layer.
