ABSTRACT:
An improved combination of box spring and mattress is provided. The mattress has a core of a particular class of flame-retarded flexible polyurethane foam and, optionally, has an outer layer of flexible polyimide foam fabricated to surround said core. The foam core, optionally with outer layer of polyimide foam, is enclosed in a flame retardant or retarded ticking (flame retarded cotton, polyvinyl chloride, fiber glass cloth, high temperature resistant polymeric fiber cloth). The box spring has a non-combustible frame and, optionally, is padded with a flame retarded flexible polyurethane foam, such as that used in the aforesaid mattress, or a flexible polyimide foam.
The box spring and mattress combination meets the requirements of present institutional fire codes and the like and represents a significantly improved product for commercial and domestic household use.
