Zigzag continuous springs — also known as no-sag or continuous wire springs — are a popular and cost-effective support system used in mattress foundations, sofa beds, RV mattresses, and budget-friendly mattress lines. Unlike Bonnell or pocket springs which are individual coils, zigzag springs are formed from a single continuous wire that creates a sinuous support structure across the entire mattress width.
The IF-Z2-PGY Continuous Spring Machine from Infinity Mattress Machinery is purpose-built for manufacturing high-quality zigzag spring units with consistent wire spacing, precise tension, and rapid production speed. Whether you produce mattress foundations, sofa cushions, or complete mattress support systems, the IF-Z2-PGY delivers reliable, repeatable results.
This guide explores continuous spring technology, the IF-Z2-PGY machine’s capabilities, and how it fits into your production line alongside other spring manufacturing equipment.

Cost vs Individual Springs
Zigzag springs, also called continuous wire or no-sag springs, are formed from a single continuous strand of wire that zigzags back and forth across the width of a mattress or foundation. Each row creates a series of interconnected support points connected by a continuous wire path.
This design offers several fundamental advantages:
Zigzag springs are widely used in mattress foundations, sofa beds, day beds, RV/marine mattresses, and economy mattress lines where cost-effectiveness is a primary concern without sacrificing essential support.
The IF-Z2-PGY is a fully automatic zigzag continuous spring forming machine designed for high-speed, precision production of sinuous spring units. It takes wire directly from the coil and forms complete spring rows with programmable spacing and tension control.
The IF-Z2-PGY is designed for manufacturers who need to produce zigzag spring units at scale. Its digital control system allows quick changeovers between different spring configurations, making it suitable for facilities that produce multiple product lines.
Understanding where zigzag springs fit in the market helps you choose the right production equipment:
One IF-Z2-PGY with 2 operators can replace 6-8 workers doing manual zigzag forming. Labor cost reduced by up to 60%.
Digital tension control ensures each spring row has identical wire spacing and deflection characteristics. Reject rates drop below 0.5%.
Precise wire feed control reduces waste by approximately 12% compared to manual forming processes.
Switch between spring configurations in under 5 minutes using pre-programmed digital profiles. No mechanical retooling needed.
The IF-Z2-PGY serves a range of mattress and furniture applications:
The IF-Z2-PGY integrates seamlessly with other mattress production equipment, complementing foam cutting lines and quilting machines in a complete production setup.
A mattress foundation manufacturer in Brazil was producing zigzag spring units using semi-automatic benders and manual assembly. With 8 workers producing approximately 400 foundation units per day, output was constrained by the manual forming bottleneck, and inconsistency across shifts led to a 5% reject rate.
After installing one IF-Z2-PGY machine:
The IF-Z2-PGY zigzag continuous spring machine is an ideal solution for manufacturers producing mattress foundations, budget mattress lines, or specialized bedding products. It combines high-speed production with digital precision to deliver consistent, high-quality spring units at the lowest cost per unit.
For manufacturers seeking to enter the zigzag spring market or upgrade existing production, the IF-Z2-PGY offers a fast path to increased capacity, reduced labor dependency, and improved product quality.
