PROBLEM TO BE SOLVED: To provide a flexible foam having excellent vibration characteristics while maintaining physical properties such as hardness and durability required as a cushion though having low repulsion. SOLUTION: The flexible polyurethane foam has≤40% core modulus of repulsion elasticity and≤1 Hz half width of the resonance transmission peak in a resonance curve. A method for producing the flexible polyurethane foam comprises reacting a high-molecular weight polyol with a polyisocyanate compound in the presence of a catalyst and a foaming agent using a specific foam stabilizer.
