The traditional sofa frame generally only uses serpentine springs. Such sofa is prone to deformation and collapse after being used for a period of time, thus affecting the beauty and use of the sofa. The sofa is designed with a combination of solid wood frame, serpentine spring and bandage, and high density rebound sponge, so that the firmness and resilience of the sofa will be doubled. Even if children jump on the sofa, the cushion is not easy to deform.

Parts made of elastic materials that deform under the action of external force and recover to the original state after removing the external force are also called "springs". The serpentine spring is flat. When the round wire strikes, it sends half an arc. When it comes out, it is serpentine. Parts made by using the elastic effect of materials are mechanical parts with elasticity. The serpentine spring is both elastic and tension, with good vibration reduction effect, long service life, high transmission efficiency, and convenient disassembly and assembly. Serpentine spring is generally used in furniture industry and coupling.

characteristic:
