Claim 0:
1. A self-inflating bed, comprising:
one or more self-inflating chambers, the one or more self-inflating chambers compressible to a compressed size and shape for shipping or storage, each of said self-inflating chambers defined between a first air impervious layer and a second air impervious layer, said first air impervious layer and said second air impervious layer each comprising a thermoplastic material having an internal side and an external side, and a thickness T of between two (2) mils (0.002 inches) and five (5) mils (0.005 inches), wherein each of said one or more self-inflating chambers further comprises a vacuum port valve;
a first bonding layer adhered to said internal side of said first air impervious layer, and a second bonding layer adhered to said internal side of said second air impervious layer, each of said first bonding layer and said second bonding layer comprising an extruded bonding composition having a finished thickness B of between one (1) mil (0.001 inch) and about four (4) mils (0.004 inches);
a number X of polyurethane foam sections N that provide a stack S of polyurethane foam sections in a series of foam sections N1 through Nx along said length L of said self-inflating bed, wherein X is a positive integer, and wherein each of said polyurethane foam sections Nx are affixed to said first bonding layer and to said second bonding layer, and wherein said one or more sections N of said polyurethane foam sections comprises an interior portion having a twenty five percent (25%) indentation force-deflection of from six (6) pounds-force to thirty (30) pounds-force as measured by ASTM standard D3574;
wherein said stack S of polyurethane foam sections has a perimeter, and extending outward from and adjacent to said perimeter, an edge portion, and wherein at least some of said edge portion comprises a polyurethane foam layer having a twenty five percent (25%) indentation force-deflection of from about thirty five (35) pounds-force to fifty (50) pounds-force, as measured by ASTM standard D3574; and,
wherein the edge jzortign and the stack S of polyurethane foam sections are both within at least one of the or more of the self-inflating chambers.
