PROBLEM TO BE SOLVED: To improve ball reboundability (a rebound elastic function) without reducing physical properties such as mechanical strengths, compressive strengths and the like of a flexible polyurethane foam. SOLUTION: In a method for forming a flexible polyurethane foam using a molding composition comprising an organic diisocyanate, a high molecular polyol, a catalyst, a foam stabilizer, a foaming agent using water or water and an arbitrary foaming agent, a low molecular compound having an adjacent carbon-carbon unsaturated bond and a carbonyl group is added to the composition as a modifier in 1-20wt.% based on the high molecular polyol.
