Coil springs are used in traditional upholstery; tension springs in modern suspension systems.\u003c\/dd\u003e\n\u003cdt\u003eWhat height and gauge of coil spring do I need?\u003c\/dt\u003e\n\u003cdd\u003eSpring height is selected based on the depth of the seat frame — typically 15-23cm (6-9 inch) springs for seat cushions. Gauge (wire thickness) determines firmness — 9 SWG is standard for seats; heavier gauges for firmer applications. The specification is in the product title.\u003c\/dd\u003e\n\u003cdt\u003eWhat is the difference between coil springs and tension springs?\u003c\/dt\u003e\n\u003cdd\u003eCoil (barrel) springs are used in traditional and high-end upholstery, tied in a grid pattern over webbing for deep, bouncy support. Tension (sinuous\/no-sag) springs are used in modern furniture, running front-to-back in a serpentine shape for a firmer, lower-profile seat.\u003c\/dd\u003e\n\u003cdt\u003eHow are upholstery coil springs tied?\u003c\/dt\u003e\n\u003cdd\u003eTraditional coil springs are tied using laid cord in a figure-8 knot pattern, connecting each spring to its neighbours and the frame.
