Abstract

A carpet underlay cushion structure is provided having a carrier layer of an open-cell, resilient polyurethane foam material substantially completely impregnated with a latex such as a non-carboxylated styrene-butadiene rubber or natural rubber, the foam material further having a woven substrate adhered thereto, the impregnated foam material being dried and cured to form a foamed, open-cell, resilient composite cushion structure wherein the open cells thereof partially comprise the carrier layer of polyurethane foam material.
