Why is it called zig zag spring?

A new sofa is often not immediately cut open to see the installed materials, such as the zig zag spring. Here you

can only rely on the manufacturer’s specifications and the expertise of the seller.

In the following, we will give you detailed information about the zig zag spring and other frequently used suspensions.

The 5 examples of different sofa designs shed light on the subject.

The zig zag springing is also often called nosag springing. Sometimes it is also called snake spring. It gets its name

because of its typical wave shape.

What material is this type of spring made of and how is it installed?

A zig zag spring is made of hardened spring steel wire and delivered to the sofa manufacturer on a roll. The higher

quality and thicker the wire, the more dimensionally stable and corrosion resistant it is. Thin zig zag spring is often

installed in inexpensive sofas. There is no minimum thickness.

Before installing the suspension, special brackets made of metal or plastic are nailed or stapled to the underside of

the sofa. The spring wire is taken from the roll with the help of a side cutter of appropriate length and hooked into the

bracket on one side. A tensioning tool is used to clamp it into the bracket on the opposite side.

When all the zig zag springs are installed, a layer of felt is placed over them. It later protects the upholstery material

against friction and slippage.
