This right angle fiberglass slat base adopts specially shaped right-angle fiberglass slats matched with thickened anti-rust steel frame. Fiberglass slats have ultra-high toughness, stable elasticity and outstanding anti-crack & anti-deformation performance, will not bend or break under long-term heavy compression. The unique right-angle edge design closely fits the inner edge of bed frame without gaps, effectively stopping slats sliding and shifting during sleep turnover. Different from wooden slats, fiberglass material is lightweight, fully moisture-proof, mildew-proof and moth-proof, solving the problem of wood decay in humid rooms. The contact surface between slats and mattress forms soft buffer, greatly reducing friction squeaks to realize silent rest. The metal frame is finished with electrostatic anti-rust spraying, solid welded structure evenly distributes human pressure, compatible with all household mattresses. This slat base is widely applied in apartment furniture, bedroom matching and large OEM bulk orders for mattress factories.
