Custom Zigzag Spring 4.8mm Sofa Zigzag Spring 

A custom zigzag spring (also known as a sinuous spring or no-sag spring) is a type of spring used in

sofa and furniture manufacturing to provide support and flexibility. The 4.8mm measurement likely refers

to the wire thickness (gauge) of the spring.

Key Features of a 4.8mm Zigzag Spring for Sofas:

• Material: Typically made from high-carbon steel for durability and resilience.

• Wire Thickness: 4.8mm (approx. 9-gauge wire, common for sturdy seating).

• Shape: Continuous "zigzag" or serpentine design for even weight distribution.

• Function: Provides support while allowing slight flex for comfort.

• Common Uses: Sofa seat foundations, backrests, and mattress support systems.

Customization Options:

If you need a custom zigzag spring, consider specifying:
✔ Length & Height (e.g., 600mm long x 100mm high)
✔ Number of Coils (more coils = softer feel, fewer coils = firmer support)
✔ End Types (straight ends, hooked ends, or loops for attachment)
✔ Tempering (heat-treated for extra strength)
