Abstract:
1. A mattress, comprising: a mattress core having opposite upper and lower portions; an upper fabric panel overlying the mattress core upper portion; a lower fabric panel overlying the mattress core lower portion; and a side fabric panel extending around a periphery of the mattress core, wherein the side fabric panel is attached along a first edge portion to the upper fabric panel and along a second edge portion to the lower fabric panel; wherein one or more of the upper, lower and side fabric panels comprises flame and heat-resistant material comprising cellulosic fibers and having a basis weight of less than or equal to about 9 ounces per square yard, wherein the flame and heat-resistant material is configured to prevent or reduce combustion of the mattress core when the mattress is impinged with a gas flame in accordance with testing protocol set forth in Technical Bulletin 603 of the State of California Department of Consumer Affairs (TB-603); wherein the upper, lower and side fabric panels comprise a chemical coating of intumescent material applied as a liquid and dried and that is configured to swell and char in the presence of a flame so as to form a barrier to the flame and to heat generated by the flame, and wherein the intumescent material, upon swelling and charring, is configured to seal openings in the upper, lower and side fabric panels and to block the passage of flame and heat therethrough; and wherein the upper, lower and side fabric panels are capable of maintaining flame and heat resistant integrity after being exposed to a flame for three minutes in accordance with the Precision Fabrics Group small scale flame and heat resistant barrier panel test (PFG Test), wherein the upper, lower and side fabric panels have a char strength of greater than or equal to 2 Newtons, and wherein a temperature on one side of the upper, lower and side fabric panels is prevented from reaching and exceeding 350° C. after about 50 seconds of flame exposure on an opposite side of the upper, lower and side fabric panels.
