Nosag Spring (Zigzag Spring) – Light Arched Variant

Light-Arched Nosag Springs for Strong and Comfortable Seat Support

Nosag springs — also known as zigzag springs or S-springs — are among the most commonly used and most reliable support systems in modern seating furniture. This light-arched version offers the perfect balance of firmness and comfort, making it ideal for seat constructions in chairs, sofas and armchairs.

We supply ready-made or custom-cut nosag springs in 3.8 mm thickness, 4.5 cm width, and up to 16 coils (approx. 64 cm). If the exact size you need is not listed, always choose the closest smaller size.

How to determine the correct length

Measure the distance between the two rails where the spring will be mounted. The spring is installed almost flat, with the arched side facing upward. The number of coils in your old spring is not the determining factor — the measurement in centimeters is what counts.

What is a coil?

A “coil” refers to one curved segment of the spring. More coils indicate a longer spring, but the true determining factor for selection is always the actual measured length.

Important notes

Please note that mounting hardware such as clips or tube hooks is not included, as this varies per furniture type. These can be ordered separately. New bottom cloth can also be added to your order.
