Triple bunk bed (a bunk bed with a pull out trundle bed). It is used, but still usable. We have upgraded to big kid beds and no longer need it. This includes two lightly used (this bed was at grandma’s house) twin mattresses each with mattress covers and 2 pairs of twin sheets. You will still need a third twin mattress for the trundle, unless you decide to use the space for storages The bed is 80 inches wide and 42 inches long (it is 80 inches when you pull out the trundle). The bottom twin bed sits at 13 inches off the ground, and the top twin is 51.5 inches high and the top railing 67.5 inches tall. The trundle sits a basically on the ground (1 inch). All three beds have nice thick slats, not the thin IKEA stuff.
