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 as well, 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 in the price. For Mattresses, order 90cm x 200cm for the top bunk and trundle bed and 120cm x 200cm for the lower bunk.
