Trundle Beds are essentially two beds which can be packed into the space that one bed would take up. This doubles the sleeping capacity at night while keeping the space free during the day. Unlike a bunk bed, trundle beds store one of the beds directly under the other that is
the height of a standard bed. One of the beds is usually smaller than the other, and the smaller bed is usually on
rollers or casters, which makes it easier to move it in and out from underneath the main bed.
Because one needs to be stored under the other, most trundle beds do not feature thick mattresses, which means that they are not ideal for people with back problems or older people, although they are perfectly suited for children and overnight guests.Trundle Beds are usually considered a pair of beds, one a twin bed, and the other slightly smaller on rollers or casters so that it may be put beneath the upper twin bed for storage. Trundle beds are a space-saving idea and allow for an extra separate bed to be available when necessary, but do not require the second space constantly.
The lower bed on some trundles can "pop-up" to be the same height as the twin it is stored beneath, creating a regular-height bed. Often used as daybeds, trundle beds are less common than bunkbeds for children. Due to storing one bed beneath the other, neither bed usually has a box-spring. When not used for sleeping, the lower bed, with mattress removed, may be used as a general storage drawer.
