A method for forming polyurethane foams for vehicle seat components in a molding apparatus is provided. The method includes a step of directing one or more polyol compositions into a mold. Each of the one or more polyol compositions includes a polyol, water, and a catalyst. The method also includes a step of directing an isocyanate composition into the mold, the isocyanate composition including one or more isocyanates. The one or more polyol compositions and the one or more isocyanates are combined into a reaction composition that forms a foamed vehicle seat component. Characteristically, the mold has a shape that defines a foamed vehicle seat component. Characteristically, either the one or more polyol compositions and/or the isocyanate composition includes a liquid antimicrobial agent that is a liquid at temperatures above 10° C.
