Using this bed rail system is easy. First, connect the angled steel rails to the headboard and footboard using the hook - in connections. Then, attach the center support bar to the rails. Adjust the height of the support leg to fit your bed, ranging from 6.5 to 15.5 inches. Place your mattress on top of the rails. When using, make sure all connections are secure to avoid any instability. For maintenance, regularly check the connections and tighten any loose parts. Wipe the metal parts with a dry cloth to keep them clean. Do not expose the bed rails to excessive moisture as it may cause rusting.
