This foldable slat base adopts hinged folding design, which can be folded into a compact size for flat packing, effectively saving warehouse storage space and greatly cutting logistics transportation costs for mattress wholesalers and furniture suppliers. The thickened steel frame is connected by high-strength folding hinges, stable and tough after unfolding, not easy to loose or deform under long-term bearing. All supporting slats are fully wrapped with thick grey grid kraft paper. The paper layer can buffer direct friction between slats and mattress, eliminate creaking noise caused by body rolling over, and realize mute sleep experience. The grey grid kraft paper has good wear-resistant and anti-slip performance, effectively protecting inner wood slats from abrasion and prolonging the service life of the bed support. The whole steel frame undergoes electrostatic anti-rust spraying treatment, with excellent moisture-proof and anti-corrosion performance, suitable for home bedrooms, short-term rental apartments and hotel projects. Scientific slat spacing evenly disperses body pressure, accelerates air circulation under the mattress, prevents dampness and mildew. This product is widely compatible with spring, latex, memory foam and all mainstream mattresses, supports size customization, bulk wholesale and OEM matching cooperation.
