Using this twin over double bunk bed is a breeze. First, follow the step - by - step instructions that come with it to assemble the bed. Make sure to place it on a flat and stable surface. When using, put suitable standard twin and full - size mattresses on the bunks. Always keep in mind that each bunk can support up to 250 pounds, so don't overload them. The full - length guardrails are there for safety, so don't remove them. For maintenance, regularly check the connections of the steel frame to ensure they are tight. You can clean the powder - coated steel frame with a mild cleaner and a soft cloth. Avoid using abrasive materials that could scratch the finish. And remember, this bed meets safety standards, but still, always supervise kids when they are using the bunk bed, especially when climbing the ladders.
