Mattresses and bedding not included. Or, for overnight guests, you can convert them into separate beds. Additional options available. The sturdy frame is made with wood slat supports, and it easily converts into two separate beds to give your children their own space. Safely equipped with ladder and slatted supports on the top bunk, the beds also look great with their curved head and footboards, and for extra storage, there is an optional three-drawer trundle.
