    Abstract: An object of the invention is to provide molded urethane foam pads and vehicle seats that can contribute to the reduction of environmental load and have appropriate impact resilience and hardness and excellent durability with good balance, and also have high comfort. A molded urethane foam pad for vehicle seats including a polyurethane is obtainable by foaming and curing materials including a plant-derived polyol (A), a non-plant-derived polyol (B), water, a catalyst, a foam stabilizer and a polyisocyanate, and has a core density of 55 to 65 kg/m3 as measured in accordance with JIS K6400; the plant-derived polyol (A) is a polyol which is obtained by condensing a polyhydric alcohol of 6 hydroxyl groups with a plant-derived, C15 or higher hydroxycarboxylic acid and which has a hydroxyl value of 45 to 55 mg KOH/g; the non-plant-derived polyol (B) is a polyol having a hydroxyl value of 18 to 26 mg KOH/g, and/or a polymer-dispersed polyol in which fine particles of a polymer of a compound having an unsaturated bond are dispersed in the polyol; and the polyurethane contains a plant-derived molecular structure and the content of the plant-derived molecular structure is 15 to 20 wt % based on 100 wt % of the molded urethane foam pad.
