🔧 18 Gauge Back Tension Springs

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.

📏 Sizes & Fitting Details

  • 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)

  • Fitting tension: Should be stretched between ½″ – 1″ for correct performance

✅ Key Benefits

  • Specially suited for Parker Knoll and similar furniture styles

  • Provides softer tension for comfort in backrest applications

  • Designed for reliability and long-lasting use

Easy to install with standard upholstery tools
