What are Zigzag Springs?

ZigZag Springs springs, also known as serpentine springs, are continuous lengths of formed steel wire shaped into a zig zag pattern. They’re stretched across furniture frames to provide firm yet flexible support. Unlike traditional Tension Springs, zig zag springs are quicker to install and are widely used in modern upholstery manufacturing.
