Armrest Hinge Sofa Cushioning Bracket Lifting Support for Backrest Headrest Versatile

The sofa armrest lifting support hinge manufactured and supplied by BLS Hardware are heavy-duty multi-angle joints engineered for adjustable sofa armrests, headrests, and pillow cushions. Stamped in our Jinli, Guangdong source factory from 2.5mm carbon steel, these precision hinges eliminate gear slippage, frame sag, and joint looseness, providing quiet and stable angular locking across functional furniture collections.

Within the integrated BLS manufacturing framework, upholstery producers combine this multi-gear sofa armrest lifting support hinge alongside high-load metal sofa legs and precision interlocking sofa connector hardware to build ergonomic modular suites. These articulation hinges also work synchronously with heavy-duty sofa bed hardware in multi-functional convertible daybeds.

Key Features of the Sofa Armrest Lifting Support Hinge

• Multi-Position Ratchet Gear: Hardened internal steel teeth provide 5 positive locking angles ranging from 90 to 180 degrees.
• Heavy-Gauge Q235 Steel: Stamped from 2.5mm cold-rolled steel arms to withstand excessive downward pressure without bending.
• Smooth Reset Spring Action: Push past the maximum angle to release the locking pawl for effortless return to zero.
• Galvanized Anti-Rust Finish: Electro-zinc coating protects interior moving parts from moisture, friction wear, and oxidation.
• Universal Mounting Flange: Pre-drilled screw slots allow rapid fixation directly into hardwood frames or tubular steel chassis.
