This is a really neat trundle-bed because of the way it is built. The top of the bed is a full size bed and the trundle is a twin, the trundle was built the same size as the full bed but then a wooden divider was installed down the inside length of the trundle allowing a twin size mattress on the outside for sleeping and storage space behind the divider on the inside edge. The storage space would be great for winter blankets and boots and such things that get stored for all the warmer months. A Crafty B. shares pictures and gives links to both the bed and the trundle plans from Ana White. This is a great way to add extra sleeping space to a small room.
