Zusammenfassung:	Disclosed are a polyurethane composition, a molded article, and a vehicle comprising the polyurethane composition or the molded article. The polyurethane composition comprises a polyol composition (A) in which polyether polyol (a1) and polymer polyol (a2) are mixed at a predetermined amount, an isocyanate composition (B) obtainable by polymerizing polyether polyol (b2) and an isocyanate composition (b1) that comprises i) methylene diphenyl isocyanate (M-MDI) and ii) polymethylene diphenyl isocyanate (P-MDI). As such, the molded article such as a vehicle seat pad can be manufactured with improved static and dynamic comfort.
