Tension spring, 533mm (21")

Tension spring, 533mm (21
Are your armchair seat springs lumpy & saggy.

Can be cut to size, and new hook bent into shape. Tension springs are usually 10% shorter than the width of the frame, however this depends on how firm you want the spring.

Easily hooked onto staples, eyes or trunkplates.

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. Tension springs are measured from 'inside the hook' to 'inside the hook'.
