The other—and maybe the biggest—concern is how much room you plan to allot between the top of the mattress and the ceiling. The “rule” is that your child should be able to sit up and reasonably move about while also being able to mount and dismount the ladder easily. A 9-foot ceiling is ideal for a bed like this.
