Using this bunk bed is easy. First, assemble it following the included instructions. Make sure to use the recommended mattress thickness - 6 inches for the top bed and 8 inches for the bottom bed. The guardrails are there to keep your child safe while sleeping on the top bunk, so don't remove them. You can use the trundle drawers to store clothes, toys, or other items. When you have guests, pull out the trundle bed for extra sleeping space. If you want, you can divide it into a captain bed with 3 drawers and a single bed. For maintenance, wipe the bed with a dry cloth regularly. Avoid using harsh chemicals as they can damage the espresso finish. Since it's not for commercial use, keep it in a home environment. And remember, due to logistics reasons, there might be some restrictions with this product.
