ODM Sinuous Zig Zag Seat Springs Customized Zig Zag Chair Springs

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.
