Using this bunk bed is easy. First, fully assemble it following the included instructions. Place 6 - inch thick mattresses on both the top and bottom beds. Make sure not to exceed the 150 - lb weight capacity on either bed to ensure safety. When someone is sleeping on the top bed, always keep the guardrails up. For maintenance, regularly check the screws and joints to make sure they're tight. Clean the wooden surface with a soft, dry cloth. Avoid using harsh chemicals as they may damage the wood. If you need to move the bed, disassemble it carefully to prevent any damage.
