Functional Sofa Headrest Hinge Adjuster

This hardware assembly adopts high-strength stamped steel with chrome-plated surface treatment. The plating layer effectively protects the metal body from rust and corrosion, ensuring stable performance even after long-term repeated use. The product comes with two optional shaft designs to meet different sofa frame assembly requirements. One version is fitted with a threaded bolt for easy locking and installation, while the other features a serrated sleeve structure for quick positioning. Both versions adopt an L-shaped bent metal rod structure, connected to a pulley assembly at the base.

The built-in pulley system is the core of this adjuster. Strict production standards are applied to the pulleys: they must be precisely assembled without mechanical play. During quality inspection, our technicians verify that all terminals stay firmly fixed on the mounting plates and that the pulley wheel runs evenly and smoothly. These controls prevent jamming, abnormal noise or loose failure during headrest adjustment. The mounting base is reserved with screw holes, which allow fast and solid fixation onto the wooden frame of the sofa.

When installed on a functional sofa, the HAO-H-H2 adjuster allows the sofa headrest to flip and lock at multiple positions. Users can freely adjust the headrest angle according to their sitting or reclining posture, relieving pressure on the cervical spine. Whether reading, watching TV or resting on the sofa, users can find their most comfortable head position.
