Give your children an ultra-cool sleeping space that they can customize at will! Constructed of metal with a gray finish, the Build-a-Bunk twin/twin bunk bed adds an instant dash of industrial style with its clean, minimalist look. And this bunk is so much more than the typical bunk bed. It has a highly customizable, space-saving design that includes a basket, short bookshelf, long bookshelf, and a tray in a gray finish. Each of these pieces is removable and can be adjusted on the left or right side of the bunk, depending on preference or room layout. You can use the bookshelves for books, trophies, or other trinkets. The basket is a great place to store games or homework close by, and the tray can easily accommodate workbooks or snacks. Mattresses and foundations (if required) sold separately.
