01SOFAS & SOFA BEDS
Concealed Iron Hinges for Smooth Folding
Tucked away within the frame of a folding sofa or lift-door cabinet, these hinges work quietly behind the scenes. Their matte black finish blends seamlessly into modern joinery, keeping the visual line clean while handling the mechanical weight of moving panels.
Designed for furniture that transforms, this pair provides the structural support needed for daily use. They suit makers and homeowners looking for a robust, low-profile solution for bed frames, storage units, or convertible seating.


02MATERIALS
High-Strength Iron Construction
Crafted from quality iron, each hinge offers the density and rigidity required for heavy-duty applications. The material is selected for its inherent strength, ensuring the component remains stable under load without warping or bending over time.

04DESIGN
Concealed Triangular Form Factor
The triangular shape allows the hardware to sit flush against the joint, minimizing its visual footprint. When the furniture is closed, the hinge disappears into the structure, maintaining a sleek, uninterrupted surface on the exterior.
05DETAILS
Left and Right Pairing
The kit supplies both a left-hand and a right-hand hinge, ensuring symmetrical installation. At approximately forty-seven-eight grams per unit, they are substantial enough to hold firm yet light enough not to overburden the door or panel they support.
