Abstract
A portable mattress assembly adapted for use in disaster relief situations having mattress support material engineered to provide a suitable balance between portability and comfort. The mattress assembly includes a fabric envelope adapted to provide a rugged, waterproofed, posterior surface, with a pocket defined therein, in combination with a more supple, water resistant, anterior surface. The fabric envelope further includes fasteners disposed to temporarily attach the mattress assembly to a cot, stretcher staffs, or additional mattress assemblies. The mattress assembly may be folded and retained in accordion fashion and provides handles thereon for portage.
Claims18
A mattress, comprising:
- a pad, the pad made from a substantially homogeneous resilient material, the pad substantially planar in shape, the pad having a predetermined substantially uniform thickness of not less than 1.5 inches and not more than 2.5 inches, the pad disposed to be folded in accordion fashion into a predetermined number of substantially equal elements;
- said resilient material having a predetermined substantially uniform density of not more than 2.5 and not less than 1.5 pounds per cubic foot, the resilient material also having a predetermined substantially uniform ILD value of not more than 50 and not less than 35;
- means for retaining the mattress folded together when the mattress is folded in said accordion fashion;
- a fabric envelope, the fabric envelope completely incarcerating the pad, the fabric envelope having an anterior surface and a posterior surface, the anterior surface of the fabric envelope made from a membrane of approximately 200 denier fabric, the anterior surface disposed to be water-repellant, the posterior surface of the envelope made from a membrane of approximately 430 denier fabric, the posterior surface disposed to be waterproof;
- at least one handle means, the at least one handle means attached to the fabric envelope, the at least one handle means disposed to facilitate portage of the mattress when the pad is folded in said accordion fashion;
- and
- the fabric envelope further providing a plurality of tying means, the tying means disposed to temporarily attach the fabric envelope to a cot, said tying means also disposed for receiving two or more staffs, said tying means further disposed for temporarily interconnecting multiple ones of said mattress together.

A mattress, comprising:
- a pad having anterior and posterior surfaces, the pad made from a substantially homogeneous resilient material, the pad substantially planar in shape, the pad having a predetermined thickness, the pad disposed to be folded in accordion fashion into a predetermined number of substantially equal elements, wherein the anterior surfaces of ones of said substantially equal elements face each other and the posterior surfaces of ones of said substantially equal elements face each other when the pad is folded in said accordion fashion;
- said resilient material having a predetermined density, the resilient material also having a predetermined ILD value;
- and
- a fabric envelope, the fabric envelope completely incarcerating the pad, wherein said fabric envelope comprises a plurality of tying means, the tying means disposed to temporarily attach the fabric envelope to a cot, said tying means also disposed for receiving two or more staffs, said tying means further disposed for temporarily interconnecting multiple ones of said mattress together.

- said resilient material having a predetermined substantially uniform density of not more than 2.5 and not less than 1.5 pounds per cubic foot, the resilient material also having a predetermined substantially uniform ILD value of not more than 50 and not less than 35, the resilient material also disposed to be fire retardant;
- a fabric envelope, the fabric envelope completely incarcerating the pad;
- and
- means for retaining the mattress folded together when the mattress is folded in said accordion fashion, wherein an anterior surface of a first one of said substantially equal elements and an anterior surface of a second one of said substantially equal elements are substantially adjacent when the mattress is retained in said accordion fashion by said retaining means.
