Method for forming a foamed product integral with trim cover assembly, in which a foam padding piece and a surface cover piece are formed such that the former is small in size relative to the latter. According to the method, the peripheral ends of the foam padding piece are aligned and sewn with the peripheral ends of the surface cover piece to form a cover section. A plurality of such cover sections are provided and are bent at their respective end portions, stretching each surface cover piece on and over each foam padding piece, after which, the thus-bend end portions of cover sections are sewn with one another to form a three-dimensional trim cover assembly. A liquid foaming material is injected and cured in that trim cover assembly to form a foamed product integral with the trim cover assembly.
