Upholstery coil springs

Upholstery coil springs are an important part of most modern upholstery. The consumer usually never sees the construction features of an upholstered piece, but they are important. The overall quality of the materials and construction techniques used dictate the comfort level of an upholstered piece and its ability to satisfy the consumer over the long term. A basic upholstered piece is composed of a frame, springs, foam, cushioning, padding, and textiles.

Coil springs are individual coils, open at both ends. They may be knotted at one end. When attached to webbing and twine-tied at the top, they form the 'springy' platform on which the loose cushion rests.
