Abstract
Abstract A multi-layered foam mattress including a lower layer having a contoured upper surface, a relatively rigid intermediate layer having a contoured lower surface engaging the contoured upper surface of the lower layer, there further being provided a resilient upper layer having a lower surface contoured and engaging the contoured upper surface of the relatively rigid intermediate layer, with all of the contoured surfaces having an inverted shape as compared to the human body resting on top of the mattress so that the mattress will tend to straighten the body.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
140 words
A mattress body support, comprising: a bottom resilient layer having a contoured upper surface; an intermediate layer having a greater firmness than said first layer and being of lesser thickness, said intermediate layer having upper and lower contoured surfaces corresponding to contour of the first layer, said upper and lower contours undulating upwardly at the user''s head, shoulders, buttocks and calves; and a top layer having greater resilience than said intermediate layer and having a substantially flat upper surface and a lower surface having a contour corresponding to the contour of the upper surface of the intermediate layer, all of said contoured surfaces having a wave-like shape that is a physical inversion of the shape of a human body, for supporting a human body over its entire length on the upper surface of the top layer in a level condition.
Claim 2
Dependent Claim
140 words
A mattress body support, comprising: a bottom resilient layer having a contoured upper surface; an intermediate layer having a greater firmness than said first layer and being of lesser thickness, said intermediate layer having upper and lower contoured surfaces corresponding to contour of the first layer, said upper and lower contours undulating upwardly at the user''s head, shoulders, buttocks and calves; and a top layer having greater resilience than said intermediate layer and having a substantially flat upper surface and a lower surface having a contour corresponding to the contour of the upper surface of the intermediate layer, all of said contoured surfaces having a wave-like shape that is a physical inversion of the shape of a human body, for supporting a human body over its entire length on the upper surface of the top layer in a level condition.
Claim 3
Dependent Claim
32 words
A mattress body support as defined in claim 1, wherein said bottom and top layers are a resilient foam material, and said intermediate layer is comprised of a relatively rigid rubber material.
Claim 4
Dependent Claim
20 words
A mattress body support as defined in claim 1, wherein said top layer upper surface is a body engaging surface.
Claim 5
Dependent Claim
140 words
A foam mattress, comprising: a bottom layer having a first resiliency, said bottom layer having a contoured upper surface, a top layer on said bottom layer having a resiliency differing from the resiliency of the bottom layer, said top layer having two substantially identical contoured surfaces corresponding to the contour of the upper surface of the bottom layer; and the upper surface of said two identical contoured surfaces of said top layer is a body-engaging surface of said foam mattress, said upper surface of the two identical contoured surfaces undulating upwardly at the point of contact with the user''s head, shoulders, buttocks and calves, all of said contours being a physical inversion of the shape of a human body, for supporting a human body over its entire length on the upper surface of the top layer in a level condition.
Claim 6
Dependent Claim
140 words
A foam mattress, comprising: a bottom layer having a first resiliency, said bottom layer having a contoured upper surface, a top layer on said bottom layer having a resiliency differing from the resiliency of the bottom layer, said top layer having two substantially identical contoured surfaces corresponding to the contour of the upper surface of the bottom layer; and the upper surface of said two identical contoured surfaces of said top layer is a body-engaging surface of said foam mattress, said upper surface of the two identical contoured surfaces undulating upwardly at the point of contact with the user''s head, shoulders, buttocks and calves, all of said contours being a physical inversion of the shape of a human body, for supporting a human body over its entire length on the upper surface of the top layer in a level condition.
Claim 7
Dependent Claim
115 words
A mattress, comprising: a bottom layer of foam material having a first resiliency, said bottom layer having a contoured upper surface; a plurality of elongated rigid members extending transversely across said bottom layer upper surface; a top layer having a resiliency different from the resiliency of the bottom layer, said top layer having a lower contoured surface engaging said transverse members; and all of said contoured surfaces being a physical inversion of the shape of a human body, for supporting a human body over its entire length on the upper surface of the top layer in a level condition, said contour surfaces including high points undulating upwardly at the user''s head, shoulders, buttocks and calves.
Claim 8
Dependent Claim
115 words
A mattress, comprising: a bottom layer of foam material having a first resiliency, said bottom layer having a contoured upper surface; a plurality of elongated rigid members extending transversely across said bottom layer upper surface; a top layer having a resiliency different from the resiliency of the bottom layer, said top layer having a lower contoured surface engaging said transverse members; and all of said contoured surfaces being a physical inversion of the shape of a human body, for supporting a human body over its entire length on the upper surface of the top layer in a level condition, said contour surfaces including high points undulating upwardly at the user''s head, shoulders, buttocks and calves.
Claim 9
Dependent Claim
32 words
A mattress as defined in claim 5, wherein said top layer is foam rubber material and has a flat upper surface, said elongated rigid members forming an intermediate layer of said mattress.
