This bunk bed has a special surprise: A pullout trundle bed! What's more, you can separate each bed so they function as two single beds. It is 1/12 scale, which is the most common scale for dollhouses and dollhouse miniatures. It means that if an object is 12 inches in real life, it is sized down to a one inch as a miniature. It measures 6 3/4" W x 6 1/8" H x 4 1/4" D.
