Back tension springs (18 gauge) are widely used in the backs of recliners, lounge chairs, and classic upholstery builds — most famously found in Parker Knoll furniture.
These springs are thinner and softer than the heavier, plastic-coated seat springs, making them ideal for providing flexible support and gentle resilience in chair and sofa backs.
Gauge: 18 (lightweight and softer action)
Use: Typically fitted across chair backs rather than seats
Length: Measurement refers to the spring section only (allow an extra ½″ at each end for hooks)
