Abstract The cords of a string net for the frame of upholstered furniture at the points where they intersect one another are fastened to one another by means of rings or clamps. The cords consist of plastics and are arranged perpendicular to the frame. The cords which are crosswise arranged to the sides of the frame are strung more tightly than the cords which are strung lengthwise to the frame sides.
