Using this Calrissian metal bunk bed is easy. First, place the bunk bed in your child's bedroom where you want it. You don't need to add a foundation or box spring, so just put the twin mattresses on the beds. For the upper bed, make sure to use a twin mattress that's no thicker than 6 inches. When your child wants to get to the top bunk, they can use the attached ladder, which is very reliable. The guard rails on the top bunk are there to keep your child safe while they sleep. As for maintenance, you can wipe the metal frame with a damp cloth regularly to keep it clean. If you notice any loose parts, tighten them right away. This will help keep the bunk bed in good condition for a long time.
