Product Descriptions

Serpentine Springs, or zig-zag springs are almost exclusively used in the manufacture or refurbishment of furniture seating. The springs are used not only in the seating element, but also in the arms and on the backs of the upholstered furniture.

Serpentine Upholstery Springs are manufactured in a continuous ‘S’ shape and sold either in specific cut lengths or a continuous length, where the user will cut the spring to a specific length dependent upon the application. The wire size used is normally standard 9 gauge spring steel wire (which equates to 0.148” or 3.76mm) for the seating application and 11 gauge (which equates to 0.120” or 3.05mm) for the backs and or arms.

Measuring

When measuring the required length, it is important to only measure the distance across the area to be bridged with the Serpentine Spring, and not allow for any bowing of the spring which may or may not be required. This measurement will make the difference between the spring fitting perfectly, or sagging or lifting of the cushion. So it needs to be right.Another factor when using serpentine upholstery springs is the distance between the springs themselves across the chair (or couch). If the gap is too wide, then the cushion will have a tendency to fall down the oversized gap. Conversely, if the gap is too small it may end up either being too strong with little or no ‘spring action’ in it, or simply be too hard to comfortably sit on. Usually a couple of inches gap, (or 50mm) is perfectly adequate. When measuring, please do not allow for the arc, the inside frame measurement is the size required.
