Stuffing in the nature of filling material composed of rubber, latex or polyurethane foam for mattresses and pillows Mattresses, pillows, finished mattress toppers

Abstract

A mattress comprising an upper foam panel and a lower foam panel, said panels molded out of a foam material with integrally preferably molded side walls; and an assembly of a plurality of spring units placed and secured on or within the lower foam panel; wherein the upper foam panel, when secured above the lower foam panel, covers the assembly of the plurality of spring units and resultantly, forms the mattress.

Abstract

A method for producing a bedding product comprising at least a foamed latex layer, said method comprising the steps of: - pouring liquid latex foam on a conveyor belt; - vulcanizing said liquid latex foam in a vulcanization station to obtain a vulcanized latex foam slab; - cutting said vulcanized latex foam slab to a desired length and/or width, characterized in that for at least partially vulcanizing said liquid latex foam electromagnetic waves with a frequency ranging between 1 and 50 Mhz are used.
