In at least one embodiment a trim cover assembly has an attachment feature for securing the trim cover to the foam cushion of a vehicle seat. The attachment feature is formed of a strip of touch-fastener material having a first side and a second side disposed adjacent a pair of trim panels. Stitching joins the first side, the second side and the trim panels to each other to form a seam in the trim cover between the pair of trim panels in order to form the attachment feature with the touch-fastener material.
