Abstract
An upholstery construction for a mattress or an article of furniture includes a flame barrier foam sheet proximate to the back face of a surface fabric layer. The flame barrier foam sheet is formed by coating or impregnating a polyurethane sheet with an aqueous solution of one or more binder(s), such as but not limited to a polyvinyl chloride copolymer or an acrylic latex binder, and one or more flame retardant(s), such as but not limited to aluminum trihydrate or melamine. The flame barrier foam sheet with dried binder(s) and flame retardant(s) not only resists flame ignition but also retains its cushioning properties.
