Abstract:
1. A mattress pad positionable atop a rectangular mattress comprising: a flexible substantially rectangular air tight bottom sheet having a size and shape substantially similar to that of a top surface of the mattress; a flexible substantially rectangular top sheet connected to said bottom sheet by peripheral air tight sealing lines along common perimeter side, head and foot margins; a plurality of generally side-by-side transversely extending body supporting air pressurizable chambers defined by said sealing lines and spaced sealing lines of continuous intermediate sealing which interconnect said top and bottom sheets through thicknesses thereof; each chamber of said plurality of body supporting chambers is selectively filled with pressurized air from a source of pressurized air; a first said chamber of said plurality of chambers positioned centrally of a width of said mattress pad and adjacent said head margin to support a head area of a person and having a first nominal air pressurized thickness between said top and bottom sheets; a second said chamber of said plurality of chambers positioned centrally of the width of said mattress pad and adjacent said first body supporting chamber to support an upper torso of the person and having a second nominal air pressurized thickness between said top and bottom sheets; a third said chamber of said plurality of chambers positioned centrally of the width of said mattress pad and adjacent said second chamber to support a lower torso of the person and having a third nominal air pressurized thickness between said top and bottom sheets; a fourth said chamber of said plurality of chambers positioned centrally of the width of said mattress pad and adjacent said third chamber to support a leg area of the person and having a fourth nominal air pressurized thickness between said top and bottom sheets; a fifth said chamber of said plurality of chambers positioned centrally of the width of said mattress pad and adjacent said fourth chamber and said foot margin to support feet of the person and having a fifth nominal air pressurized thickness between said top and bottom sheets; said first thickness being greater than said second thickness which is greater than said fourth thickness which is greater than either of said third or fifth thicknesses.
