Frequently Asked Questions
Does this mechanism require electrical power or gas pistons to shift?
No. The BLS-FB02 is an engineered manual mechanical 4-bar linkage that uses balanced weight geometry for smooth, effortless manual shifting without electrical wiring or maintenance.
How many hinges are needed per sofa backrest section?
For individual single-seat backrests, 1 matched pair is typically used. For wide 2-seater or 3-seater one-piece moving backrests, we recommend installing 2 to 3 hinges synchronized across the frame.
What is the typical factory MOQ and sample lead time?
Standard factory MOQ is 300 sets. Free evaluation samples are available and dispatch within 2–3 business days; volume container orders take approximately 20 days directly from Jinli, Guangdong.
