zigzag spring (also called sinuous spring, no-sag spring, or serpentine spring) is a type of spring

commonly used in furniture, particularly sofas, chairs, and mattresses, to provide flexible and durable support.

Key Features of Zigzag Springs

1. Shape:

   • Made from a continuous steel wire bent into a repeating "S" or "M" pattern.

   • Resembles a zigzag or wavy line, hence the name.

2. Material:

   • Typically made from high-carbon steel or tempered steel for durability.

   • May be coated with zinc, vinyl, or epoxy to prevent rust and reduce noise.

3. Function:

   • Provides flexible yet firm support for seating surfaces.

   • Absorbs weight and returns to shape, preventing sagging over time.

   • Often used in place of traditional coil springs for cost efficiency and ease of installation.
