PROBLEM TO BE SOLVED: To provide a flexible polyurethane foam excellent in durability and low resilience and having little hardness change with respect to temperature change, and a method for producing the same. SOLUTION: A flexible polyurethane foam having a glass transition point of 5 ° C. or lower, higher than 5 ° C. and lower than 70 ° C., and having a core rebound resilience of 15% or lower; alkylene with a composite metal cyanide complex catalyst A polyol (A) having an average hydroxyl number of 2-3 and a hydroxyl value of 10-90 mgKOH / g and a polyol (B) having an average hydroxyl number of 2-3, hydroxyl value of 15-250 mgKOH / g, which is obtained by ring-opening addition polymerization of an oxide. A production method in which a polyol and a polyisocyanate are reacted. [Selection figure] None |
