Material Selection: Support frames use “North American imported ash/oak”—treated with 6 rounds of high-temperature drying (moisture content controlled at 8%-12%) to prevent warping in humid southern regions or cracking in dry northern areas;
Craft Details: Adopt “mortise and tenon + hardware reinforcement” dual structure (traditional mortise and tenon boosts stability, hardware aids load-bearing); a single sofa frame can support ≥800kg (equivalent to 6 adults sitting simultaneously);
Eco-Friendly Attributes: Solid wood contains no formaldehyde, and is finished with water-based paint (VOC content meets EU E0 standards)—safe for families with pregnant women or children;
Durability Testing: Simulating daily use (frequent sitting, moving), the solid wood support frame has a lifespan of ≥15 years—3 times longer than ordinary particleboard frames.
