ABSTRACT OF THE DISCLOSURE Disclosed is a smolder resistant upholstered furniture or mattress assembly and a method for render- ing the composite materials of such assembly smolder resistant. Placement of a layer of sulphur immediately adjacent a normally smolder-prone material in the composite effectively prohibits the advance of smoldering combustion to a dangerous stage. The sulphur layer is advantageously applied by backcoating the fabric overlay, coating or impregnating the fibrous or polyurethane foam materials or separating layers of such materials with sulphur- containing films, fabrics and the like. An advantage usly effective amount of sulphur is from about 25-50 g/m2 to about 250-300 g/m2 in a layer having a depth of about 1 to 3 mm.
