This sofa frame is equipped with premium full extension 3-stage slide rails, which can pull out the sofa bed board to full length without limiting activity space, convenient for daily rest and temporary guest accommodation. Compared with ordinary two-section slides, three-stage rails have larger stretching stroke, smoother sliding and stronger load-bearing capacity.
The main frame is made of thickened high-strength steel tubes with full welding and multi-group reinforcing beams, stable and anti-deformation under long-term sitting and lying pressure. The slide rails adopt mute wear-resistant hardware, with built-in buffer function to avoid hard impact noise when pushing and pulling.
Multiple support slats are optional: solid wood slats, fiberglass slats and paper-wrapped slats. Scientific spacing evenly disperses pressure on sofa cushions to prevent local sagging. All metal surfaces are sprayed with environmentally friendly electrostatic anti-rust paint, scratch-proof, moisture-proof and corrosion-resistant for long service life.
Silent rubber gaskets are installed between slats and steel frame to eliminate friction squeaks when sitting or rolling over. Ventilation gaps between slats keep air flowing under the cushion and prevent dampness and mildew.
Split flat-pack design greatly reduces packaging volume and transportation cost, with quick lock fittings for easy tool-free assembly. Custom sizes, bulk wholesale and OEM customization are available for sofa factories.
