A method for producing a vehicle seat pad, comprising Step (I) of obtaining flexible polyurethane foam by allowing an active hydrogen component (A) and an organic polyisocyanate (B) to undergo a reaction in the presence of a foaming agent (C), a urethanation catalyst (D), a foam stabilizer (E) and an additive (F), wherein the (C) contains water, the (F) contains at least one kind selected from the group consisting of a urea compound (F1) represented by general formula (1) below, an amino acid (F2) and a polyhydric phenol (F3), the flexible polyurethane foam has a core density of 25 to 90 kg/m3, a resilience of 50 to 75% and a hardness (25%-ILD) of 150 to 400 N/cm2.
- [In general formula (1), R represents a hydrogen atom, an alkyl group with 1 to 4 carbon atoms or a hydroxyl group, Rs may be the same as or different from one another, but at least one of Rs represents a hydrogen atom. n represents an integer of 0 to 3.]
