Super Star. Our Sundance seven-piece Twin loft bed is a hit with its solid pine construction and space-saving design. Packed with ample drawer space and a built-in bookcase, as well as a desk and bulletin board, there are features galore! The lower Twin bed is set on casters, making cleaning a breeze and giving you flexibility as children grow and move to individual rooms. *** Bunkie Boards are required to provide proper support for your mattress. All Sundance beds come with 3 wood slats.
