A method of preparing a molded article comprising (a) a rigid support, e.g., a rigid seat support (10), having a plurality of perforations, and (b) a molded flexible hollow thermoplastic member (20), e.g., a flexible thermoplastic seat cushion, fixedly attached thereto is described. During the blow molding step a portion of the thermoplastic parison precursor of the flexible hollow member (b) extends through at least some of the perforations of the rigid support (a), embedding the edges of the perforations therein. The flexible material extending through the perforations forms an attachment means, e.g., an attachment head, that serves to fixedly attach the flexible hollow member (b) to the rigid support (a).
