This floating iron bed frame adopts thickened high-strength iron pipe as raw material and integrated full welding process to build a solid load-bearing structure. It adopts hidden suspension design without exposed support legs around the bed, presenting a light, minimalist and advanced visual floating effect, matching light luxury, modern and simple home decoration styles. Multiple reinforced cross beams are installed inside the frame to evenly disperse pressure, with strong bearing capacity, no shaking, bending or loose welding points under long-term use. The whole iron surface is treated with environmental electrostatic anti-rust spraying, scratch-resistant, moisture-proof and anti-corrosion, easy to wipe and clean, and can maintain long service life in humid home environment. The bottom leaves a large ventilation gap, forming uninterrupted air circulation under the mattress, effectively avoiding damp accumulation, mildew growth and peculiar smell, and protecting the mattress from damp damage. Silent anti-friction gaskets are equipped at the connection between slats and iron frame to eliminate creaking noise when turning over, creating a quiet sleeping environment. The edge of the iron frame is smoothly polished without sharp burrs to avoid accidental bumps. It is widely compatible with all types of mattresses such as spring, latex and memory foam, supports customized size, mass wholesale and OEM supporting cooperation for furniture and mattress factories.
