ABSTRACT:
An improved mattress includes a composite made of a layer of a fire retardant material capable of providing a heat barrier bonded to a layer of high tensile strength material, such as fiberglass fabric. The composite encloses at least most and generally practically all of the flammable ingredients of the mattress. When exposed to a fire, the fire retardant material chars, thereby creating a heat shield that protects the inside of the mattress while the high tensile strength material holds the mattress together and prevents the mattress from bursting open thereby exposing the flammable ingredients thereof to the fire.
The composite of the present invention is made by bonding a fire-retardant material capable of providing a heat barrier to a high tensile strength material.
