A bunk bed is a bed type with one frame stacked on another, allowing multiple people to sleep in limited floor space. They are commonly used in places like dormitories, hostels, and army garrisons, supported by four poles and accessed via a ladder. The top bunk includes safety features like railings and is not recommended for children under six, while a loft bed offers similar height benefits without a lower bunk.

1. bunk bed
A bunk bed is a type of bed in which one bed frame is stacked on top of another. The nature of bunk
beds allows two or more people to sleep in the same room while maximizing available floor space.
This leads to them being used in places with limited floor space, such as on ships and in
army garrisons or in places that wish to maximize bedspace such as:dormitories, summer camp
cabins, hostels, children's rooms, prison cells, or universityresidence halls.
Bunk beds are normally supported by four poles or pillars, one at each corner of the bed. To get to the
second bunk a ladder is used. The top bed is normally surrounded by a railing to prevent the sleeper
from falling out, and some models also have a privacy curtain for the lower bunk. Because of the need
for a ladder and the height of the bed, the top bunk of a bunkbed is not recommended for children
under six years of age.

A loft bed is an elevated bed similar to a bunk bed, but without the lower beds - freeing floor space for
other furniture (such as a desk) which might be built into the loft bed.
