This detachable curved slat base features a split disassembly structure for flat packaging, which greatly cuts down storage and transportation volume and reduces overall logistics expenses for distributors and mattress manufacturers. The ergonomic curved slats fit the natural curve of human spine, evenly disperse body pressure on waist, back and hips, relieve fatigue and deliver more comfortable sleeping support compared with flat slats. The thickened spliced steel frame adopts quick connecting locks for fast assembly without professional tools, and the finished whole frame owns strong stability and excellent load-bearing capacity without shaking or loose joints. All steel components are coated with electrostatic anti-rust paint, featuring moisture-proof, anti-corrosion and scratch-resistant performance to fit long-term use in residences, rental apartments and hotel rooms. Silent cushion pads are added between curved slats and metal frame to buffer friction, eliminate creaking noises when users roll over and maintain quiet sleep environment. The gaps between curved slats keep smooth air flow under the mattress, avoid damp buildup, mildew and peculiar smell, and extend the service life of matched mattresses. It is perfectly compatible with spring, latex, memory foam and all common mattresses, supporting custom sizes, bulk wholesale and OEM supporting cooperation.
