Abstract: An automotive vehicle seat cushion is provided including a resilient body with a top surface and a bottom surface and a multi-dimensional bore intersecting the top and bottom surfaces, the bore having a shoulder juxtaposed between the top and bottom surfaces; a membrane cover for covering at least a portion of the top surface of the resilient body and having connected thereto a rod extending generally parallel to the top surface; and a retainer which has a base adjacent the resilient body bore shoulder, a hook extending from the base with an opening toward the resilient body bottom surface, and a guide for aligning the cover rod to a location between the guide and the hook to capture the rod and thereby retain the cover to the resilient body.
