50mm Height 20mm-40mm Width 2.0mm-4.0mm Wire Diameter Zigzag Spring for Sofa and Furniture

Adopting a one-piece bending process with high-carbon steel, it features a seamless design without splicing joints, avoiding loosening or displacement issues of modular springs after long-term use. The wave-shaped structure creates a uniform force transmission surface, dispersing pressure more evenly. Even in high-frequency use scenarios such as sofas and bed frames, it effectively resists local sagging and maintains the flatness of furniture frames. Compared with spliced springs, its structural strength is increased by more than 50%, suitable for large-sized sofas, heavy-duty office chairs and other products requiring high support stability, meeting long-term use needs without additional reinforcement.

Eliminating complex processes such as independent pocketing and modular assembly in production, its cost is lower than that of pocket springs while maintaining core support performance, making it a cost-effective choice for furniture manufacturers' bulk procurement. The spring itself adopts a lightweight design, with a single unit weight reduced by 20% compared to traditional connected springs, which does not increase the overall weight of furniture and facilitates transportation and installation. In addition, it can be directly embedded into furniture frames made of solid wood, metal and other materials without complex adaptation processes, suitable for full-range upholstery products such as sofas, bed frames and leisure chairs, significantly reducing manufacturers' product adaptation costs.

The wave-shaped structure inherently has elastic buffering characteristics, which can quickly absorb the impact force when people sit or lie down, reduce vibration transmission to the furniture frame, and extend the service life of the overall furniture. The surface is treated with a silent coating, combined with the dispersed design of wave-shaped contact points, completely eliminating friction noise between the spring and the frame, as well as between the spring and the fabric, maintaining a quiet use environment. Meanwhile, the galvanized or electrophoretic anti-rust treatment on the spring surface can resist erosion from complex environments such as humidity, acid and alkali, suitable for scenarios such as humid southern regions and semi-outdoor leisure furniture, and can be used stably without additional protection.
