A flexible polyurethane foam formulation which is non-reactive at or near ambient temperatures is provided. The formulation comprises a polyisocyanate, a polyfunctional active hydrogen containing compound, an amine catalyst, a blowing agent and a polyether acid. The formulation which becomes reactive above 40.degree. C. has the advantage, over similar systems based on formic acid, that the polyurethane foam is not tight and does not suffer from skin peeling.
