Product Descriptions
Zigzag Spring (aka No-Sag Spring, Sinusoidal Spring): A continuous, pre-bent wire spring that forms
a series of "M" or "Z" shapes. It's used in sofa frames for providing foundational support, often tied down
with helical springs for a more responsive feel.
3.0-4.0mm Wire Diameter: This is an extremely heavy-duty specification.
Standard residential sofas typically use 1.8mm - 2.5mm wire.
3.0mm+ is reserved for commercial, heavy-use, or high-end luxury applications (e.g., contract furniture
for hotels, airports, waiting rooms, or premium home furniture designed for maximum longevity and
weight capacity).
