10g Serpentine Spring

Sold As: 100 ft coil

The 10g Serpentine Spring (also known as sinuous or zig-zag spring) is a staple component in modern upholstery, providing reliable support and comfort across a wide range of furniture projects. Designed to be fixed across chair and sofa frames in a series of parallel rows, these springs create a flexible, even suspension system that stands the test of time. Whether you’re reupholstering a favourite armchair or building new furniture from scratch, serpentine springs offer a neat, space-saving alternative to traditional coil spring systems.

This 10 gauge wire gives an excellent balance of firmness and flexibility, making it suitable for seat and back cushioning in domestic sofas, chairs, and settees. The spring clips easily to your frame using the appropriate hinge clips and border wire, and can be cut to the exact length you need for a precise, professional fit. It’s a go-to choice for both trade upholsterers and keen DIYers looking to achieve a quality, long-lasting result.

Supplied as a generous 100 ft coil, this product gives you plenty of material to tackle multiple projects or larger pieces of furniture without running short mid-job. Simply unroll, measure, cut, and fix — it really is that straightforward. Browse our full range of serpentine spring accessories including hinge clips, border wire, and spring wire to complete your upholstery toolkit.
