Abstract
A pillow top mattress is made by first folding a mattress core border strip lengthwise to form at least one integral pillow top border, cutting diamond-shaped notches out of the folded edge, and sewing the free edges of the notches together to form mitered corners. The strip is cut to length, and after its ends are joined together to form a band, it is pulled over the mattress core. The border strip is then secured to the core material, and pillow top insulation is added before a pillow top panel is sewn to the free edge of the border strip.
