Using this twin bed frame with trundle is easy. When you need an extra bed, just pull out the trundle from under the main bed. To put it away, simply push it back. You can use the 13 - inch clearance under the bed for storing items like clothes, toys, or extra bedding. For maintenance, use a soft, dry cloth to wipe the bed frame regularly. Avoid using harsh chemicals as they may damage the manufactured wood. Since no assembly is required, you can start using it right away. Just make sure to place it on a flat surface to ensure stability. When choosing a mattress, consider the slat kit for support and pick one that fits the twin size of the bed.
