Abstract:
1. A flame resistant mattress comprising: a mattress not originally manufactured to meet a full-scale open flame resistant fire standard; a cover for at least partially enclosing the mattress, the cover comprising a unitary, integrally formed fabric having a fire barrier element comprised of char-forming, inherently flame retardant fibers; wherein the fabric further comprises a unitary, integrally formed multilayer knitted fabric, made from a knitting process, having at least two layers, including a knitted outside layer and a knitted fire barrier layer, the multilayer knitted fabric being unitary and integrally formed, such that the outside layer is knitted together with the fire barrier layer during the knitting process such that the multilayer knitted fabric does not require additional stitching to maintain structural integrity; wherein the fire barrier layer provides flame-retardant and/or flame-resistant properties to the entire fabric without requiring fabric coatings or treatments to provide any contribution to flame retardance or resistance; and wherein the cover is removably attachable to the mattress, and wherein the mattress, when at least partially covered by the cover is rendered open flame resistant to a full scale fire test, thereby providing a flame resistance and/or flame retardance.
