PROBLEM TO BE SOLVED: To provide a method for producing flexible polyurethane foam with excellent vibration characteristics without combining different foams. SOLUTION: The invention relates to the method for producing flexible polyurethane foam by reacting a polyol component and an organic isocyanate component in the presence of a foaming agent, a catalyst and a foam stabilizer, wherein the polyol component comprises (A) a polymer polyol obtained by polymerizing a vinyl based monomer in a polyol (a), or a polyol component containing the polyol (A) and a polyol (B) and the polyol (a) and/or polyol (B) contain three kind of polyols with specific composition, and the foaming agent is water.
