Our bunk bed with stairs has a single bunk on the top and a twin bunk on the bottom. Having a bunk bed with stairs is so much easier to change the bed aswell, but with the ladder there for fun too. Lovely detailing on the window and crown for that special touch. Underneath the bottom bunk is a trundle / pull out bed for those extra guests. The stairs have lift up tops to access storage compartments within. Please note that mattresses are not included with the price.
