However if the span is too great, a person's weight can push the springs apart not allowing enough support in the seat base. By simply fixing this wire across the springs from side to side about 6 inches from the front or back it will prevent them from separating and eventually breaking. \u003cbr\u003eThe wire will give the seat more support and so make it more comfortable as well as extending the life of the seat. What makes this product different is the soft paper covering which helps prevent noise if metal rubbed on metal.\u003cbr\u003e\u003cb\u003e Fix with border wire clips\u003cbr\u003e\u003c\/b\u003e This item is available either in a 500m roll or in multiples of 2m (ie: 2, 4 or 10 metres).

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. Springs are lashed in both directions (front-to-back and side-to-side) to prevent tilting.\u003c\/dd\u003e\n\u003cdt\u003eWhy choose Upholstery Warehouse for springs and suspension?\u003c\/dt\u003e\n\u003cdd\u003eUpholstery Warehouse stocks a comprehensive range of upholstery springs and suspension components used by professional upholsterers across the UK, at trade prices with fast despatch.\u003c\/dd\u003e\n\u003c\/dl\u003e","brand":"Upholstery Warehouse","offers":[{"title":"Per meter(min 2m)","offer_id":57210096779604,"sku":"SPSW","price":3.19,"currency_code":"GBP","in_stock":true},{"title":"500m","offer_id":57210096812372,"sku":"SPSWRL","price":257.98,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1072\/6552\/4052\/files\/Silent-Wire2-1024x1024-1.jpg?v=1789826892","url":"https:\/\/upholsterywarehouse.co.uk\/products\/spsw-p","provider":"Upholstery Warehouse","version":"1.0","type":"link"}
