Using this bunk bed is easy. First, make sure you have a flat and stable surface in your bedroom. Since full assembly is needed, follow the instructions carefully to put the bed together. Place 6 - inch thick mattresses on both the top and bottom beds, and keep in mind the 150 - lb weight limit for each bed. The guardrails on the upper bunk are there for safety, so don't remove them. When it comes to maintenance, use a soft cloth to wipe the wooden surface regularly. Avoid using harsh chemicals as they can damage the wood. If you notice any loose parts, tighten them up right away. Enjoy the space - saving and stylish addition to your bedroom!
