A mattress construction and method of making is disclosed in which an extremely wide, deep stitch flange permits a more uniform and tighter mattress construction. A mattress cover is sewn to an apron or flanging material with a wide border or flange with the thread being deeply set in the cover by the thick foam padding between the flange material and the cover. This construction allows the apron to be very tightly pulled over a coil spring and stapled through sisal padding to the coil spring rim or border. The stretching of the flange skirt and cover creates a bow in the coil spring pulling the rim toward the center. The wide flange then permits the skirt or side cover to be tightly stitched with edging tape or binding material to produce a very firm and flat mattress construction. |
