Familiar to many a sibling, a bunk bed is a type of structure in which one bed frame is stacked on top of another. The benefit of a bunk bed is that it allows two people to share a sleeping space without losing floor space. This may be why they are perfect for children around the same age or in smaller rooms such as dormitory rooms or camp cabins. The beds are supported by four pillars, one for each corner. To reach the top bed (surrounded by a railing for safety), a ladder is used.
