A mattress, foundation, or other upholstered sleep product or article includes a core and barrier material surrounding the core. The barrier material includes flame and heat-resistant material that is configured to prevent combustion of the core when the upholstered article is impinged with a gas flame according to California Technical Bulletin 603 of the State of California Department of Consumer Affairs. The barrier material may include an intumescent material 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.

The disclosure relates to curable polysilyl phosphate compounds and compositions as well as related methods and flame-retardant textiles incorporating the same. Curable polysilyl phosphate compounds according to the disclosure include a hydrocarbon moiety comprising at least one phosphate group and more than two hydrolysable silyl groups linked to the hydrocarbon moiety. In some embodiments, the hydrocarbon moiety is derived from spirocyclic pentaerythritol diphosphoryl chloride. The curable polysilyl phosphate compound can applied to a textile substrate and then cured to provide a flame-retardant textile with the cured polysilyl phosphate compound as a coating bonded to the textile substrate.
