Using this bunk bed is a breeze. Just let your kids use the built - in ladder to climb up to the top bunk and the slide to come down. When choosing mattresses, remember that the recommended thickness for both the top and bottom beds is 6 inches. For safety, always make sure your child uses the top bunk with the guard rails up. To keep the bunk bed in good condition, wipe it down regularly with a soft, dry cloth. Avoid using harsh chemicals or abrasive cleaners as they can damage the solid pine wood. If there are any loose parts, check the connections and tighten them gently. This bunk bed doesn't need assembly, but if you're using it commercially, do a regular safety check to ensure everything is in place.
