A composition for making a polyurethane foam includes a non-fugitive tertiary amine urethane catalyst and amidoamine and/or imidazoline crosslinking additives. Foams prepared from the reaction of a polyol and an organic isocyanate in the presence of these ingredients show excellent resistance to deterioration of physical properties upon humid ageing.
