Black Sofa Coil Springs , 6" x 12 Gauge Sofa Double Cone Springs For Sofa Seat And Cushion

Double Cone Springs

Double Cone Springs,also known as Bonnell springs,are typically used for spring support in traditional upholstery and divans. Many different sizes are available to suit individual applications. Our springs are manufactured in plain finish and to the highest of standards for maximum comfort and reliability.

Do not forget that new springs will be very strong in comparison to those you have removed. It may be necessary to replace with a size smaller to be kind to an old frame. Also think carefully if replacing only some springs in a seat, it may be better to replace the whole set. The higher the gauge number the thinner the wire.

e.g
1. 12 gauge for backs only.
2. 10 gauge for seats and firmer backs.
3. 9 gauge or lower for seats only.

Strength is variable in double cone upholstery springs

The strength of the spring can be infinitely varied to adapt to the user requirements. This can be achieved using any one or all combinations of wire size, number of coils, the free length of the spring, outside diameter of the end coils (which are usually closed coils) and the amount of taper reduction in the helix of the inner reducing coils, back to its full size at the other end of the spring.

In practice the spring tend to be really strong when first fitted, but a certain amount of collapse will inevitably happen after a short time, so careful selection of all of the above variants will need to be calculated for any given application.

Fixing

The method of fixing double cone coil springs in place is the top and bottom coils are sewn into position or fixed across webbing (on furniture applications). Stability of the top and bottom of the spring is imperative, as without secure fixing the spring will become unstable and topple over from one end or the other and render its use inoperable.
