Claim:
1. A method of forming a combination of gelatinous elastomer and open cell flexible polyurethane foam comprising: introducing a copolymer resin selected from the group consisting of a triblock copolymer resin, a diblock copolymer resin, and combinations thereof, into a mixture of open cell flexible polyurethane foam forming components comprising a polyol and an isocyanate, where the copolymer resin is a triblock copolymer resin selected from the group consisting of styrene-ethylene-butylene-styrene (SEBS), styrene-ethylene-propylene-styrene (SEPS), styrene-ethylene-ethylene-propylene-styrene (SEEPS), and combinations thereof; and the diblock copolymer resin, if present, is selected from the group consisting of styrene-ethylene-propylene (SEP), styrene-ethylene-butylene (SEB), styrene-ethylene-ethylene (SEE), and combinations thereof; and simultaneously polymerizing the copolymer resin to form the gelatinous elastomer in-situ while polymerizing the polyol and the isocyanate to form an open cell flexible polyurethane foam; where the copolymer resin is added in the range of about 0.1 to about 200 parts per hundred of the polyol component of open cell flexible polyurethane foam.
