Abstract: A cover member for a vehicle seat and back having smooth curved and contoured rounded corners. In forming the curved corners, a first fabric cover member is sewn with shirr stitching along the edge of the member around the corner to form a shallow pocket in the member. When the first and a second cover member are then sewn together and turned inside out, a smooth, rounded corner is formed having no puckering or darting along the seam thus formed between the cover members. The cover thus formed is then placed over a preshaped molded foam pad adapted to be mounted on a conventional seat back frame. The shirr stitching along the edge of the corner uniformly gathers the material along the edge of the corner presenting a curved surface in an otherwise flat fabric material. Shirr stitching is also utilized in the seat to enable the use of non-stretch fabric in covering irregularly shaped seats.
