Does your vintage recliner chair have a saggy bottom? Replace the zig-zag / no-sag springs to firm it up again. Various lengths.
Hints & Tips
Coil Springs: Coil springs are secured onto jute webbing, rails or onto a wooden base. The top of the springs are tied together with jute twine, &/or sewing onto hessian. Use a large curved needle for sewing jute webbing.
Zig Zag springs: Also known as sinuous, serpentine or no-sag springs. These are installed onto a frame with spring clips. The spring is usually longer than the width of your frame so it has a crown/arch. Tie the springs together in two or three spaces with jute twine, then cover the springs with hessian before adding the foam.
Tension springs: These are often found on mid century chairs. The springs are approx 10% smaller that the frame span so that the spring stretches across. For a tight seat (ie: foam and fabric is stapled onto the frame) cover the springs with hessian before adding the foam. For a loose seat (ie: you have loose cushion seating), cover the springs with quilted lining.
