Bunk bed

Bed in which one bed frame is stacked on top of another bed

A bunk bed or set of bunks is a type of bed in which one bed frame (a bunk) is stacked on top of another bed, allowing two or more sleeping-places to occupy the floor space usually required by just one. Bunks are commonly seen on ships, in the military, and in hostels, dormitories, summer camps, children's bedrooms, and prisons. Bunk beds are normally supported by four poles or pillars, one at each corner of the bed.
