    Key Features & B2B Manufacturing Advantages

    1. Synchronized Scissor Linkage Geometry
      The multi-pivot steel geometry shifts seat and backrest cushions smoothly during folding, ensuring flush alignment when fully expanded into bed mode.

    2. Corrosion-Resistant Electro-Zinc Coating
      The electro-galvanized surface layer passes salt-spray anti-rust testing, preventing corrosion inside foam and fabric padding over years of use.

    3. High Torque Resistance & Zero Slop
      Hardened pivot rivets and thick steel plates eliminate side-to-side wobble and joint slop when users sit or lie on the converted furniture.

    4. Streamlined Factory Production Line Assembly
      Equipped with pre-drilled countersunk mounting holes, factory workers can screw the left and right hinge assemblies rapidly into wooden inner frames.
