Why High-End Upholstery Brands Choose the BLS Ratchet Joint
In high-end functional furniture, poor headrest hinges lead to loose backrests and noisy clicks. Our sofa headrest ratchet hinge provides premium build advantages:
- Precision-Milled Gear Teeth: High-carbon steel internal gears ensure crisp, positive locking at every angle without play or wobble.
- Smooth Reset Action: Pushing the headrest to maximum travel smoothly disengages the ratchet pawl, allowing effortless return to the flat position.
- Zero-Distortion Solid Pin: The solid L-shaped pin withstands heavy leaning weight from tall users without permanent deflection or frame binding.
