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.

Fire-resistant mattress and high strength fire-retardant composite

An improved mattress innerspring unit is provided which includes a plurality of rows of coil springs and a plurality of cross helicals which extend transversely of the rows of coil springs, lacing together adjacent terminal convolutions of the coil springs, wherein a welding means is provided to eliminate the tendency of the cross helicals to spin-out of the unit. Also provided is a method of constructing an innerspring unit which includes welding an end revolution of a cross helical to another component of the unit or to an adjacent cross helical revolution.

Innerspring construction

An improved mattress innerspring unit is provided including cross helicals which extend transversely of the rows of coil springs and lace together adjacent terminal convolutions of the springs in a row and a retention and support strip which overlies the terminal convolutions of the springs in a row of the unit, the retention and support strip and the helicals being crimped together and otherwise secured about the interlaced portions of the coil springs. The cross helicals are prevented from spinning out of the unit and the unit is firmed, particularly in the area close to the retention and support strip. Preferably, retention and support strips are provided along both the top and bottom terminal convolutions of the coil springs of at least one row near each of the two longitudinal edges of the innerspring unit.
