A novel flexible polyurethane foam having good vibration characteristics and being excellent in occupant posture stability, is provided. A flexible polyurethane foam obtainable by reacting a high molecular weight polyoxyalkylene polyol or a polymer-dispersed polyol containing fine polymer particles in the high molecular weight polyoxyalkylene polyol, with a polyisocyanate compound in the presence of a catalyst, a blowing agent and a foam stabilizer, characterized in that as at least a part of the foam stabilizer, the following fluorinated compound (F) is used in an amount of from 0.00001 to 1 part by mass per 100 parts by mass of all active hydrogen compounds: fluorinated compound (F): a compound which is a copolymer of a fluorinated acrylate or a fluorinated methacrylate (p), an alkyl acrylate having a long chain alkyl group, an alkyl methacrylate having a long chain alkyl group, an acrylate containing an oxyalkylene group or a methacrylate containing an oxyalkylene group (q), and optional other copolymerizable monomer (r), wherein the fluorine content is from 12 to 50 mass %.
