Using this twin bed frame with a trundle is a breeze. To use the trundle, simply pull it out from under the main bed when you need an extra sleeping space. When not in use, push it back under the bed to save space. As this bed is made for toddlers or children, always make sure kids use it safely. Since it doesn't require assembly, you can start using it right away. For maintenance, regularly check the slats and the frame for any signs of wear. Wipe the bed with a soft, dry cloth to keep it clean. Avoid using harsh chemicals or abrasive cleaners as they might damage the manufactured wood. With proper care, this bed will serve you and your family for a long time.
