Chair Springs Double Cone
Chair Springs Double Cone - Available in a variety of sizes and gauges. It is suggested you use: 12 Gauge for arms and backs only. 10 Gauge for seats and some firmer backs. 8-9 or less Gauge for seats only. These springs are also known as hourglass or waisted springs
These double-cone springs are used in your upholstery to ensure that the seat is returned to its original position and that seats, arms and backs provide the required support.
It is best to replace a set of springs together, and the new chair or sofa springs will be much stronger in comparison with those replaced.
The sizes are shown as 'height x wire thickness', therefore 'inch x gauge'. The higher the gauge number, the thinner the wire.
