A box-spring (or divan in some countries) is a type of bed base typically consisting of a sturdy wooden frame covered in cloth and containing springs. Usually, the box-spring is placed on top of a wooden or metal bedframe that sits on the floor and acts as a brace, except in the UK where the divan is more often fitted with small casters. The box-spring is usually the same size as the much softer mattress placed on it. Working together, the box-spring and mattress (with an optional bed frame) make up a bed. It is common to find a box-spring and mattress being used together without the support of a frame underneath, the box spring being mounted directly on casters standing on the floor.

Box-spring in the context of Bed
A bed is a piece of furniture that is used as a place to sleep, rest, and relax.
Most modern beds consist of a soft, cushioned mattress on a bed frame. The mattress rests either on a solid base, often wood slats, or a sprung base. Many beds include a box spring inner-sprung base, which is a large mattress-sized box containing wood and springs that provide additional support and suspension for the mattress. Beds are available in many sizes, ranging from infant-sized bassinets and cribs, to small beds for a single person or adult, to large queen and king-size beds designed for two people. While most beds are single mattresses on a fixed frame, there are other varieties, such as the murphy bed, which folds into a wall, the sofa bed, which folds out of a sofa, the trundle bed, which is stored under a low, twin-sized bed and can be rolled out to create a larger sleeping area, and the bunk bed, which provides two mattresses on two tiers as well as a ladder to access the upper tier. Temporary beds include the inflatable air mattress and the folding camp cot. Some beds contain neither a padded mattress nor a bed frame, such as the hammock. Other beds are made specifically for animals.

A bed base, sometimes called a foundation, is the part of a bed that supports the mattress. The bed base can itself be held in place and framed by the bedstead (bed frame). In the United States, box-spring bed bases are very common (to the point where 'bed base' and 'box spring' may be used synonymously, and the term "platform bed" is used for any other type of bed base). In Europe, sprung slats are much more common.
Typically the measurements of a foundation will be about 1–2 inches (2.5–5.1 cm) shorter than the measurements of a mattress. In hot climates, mattress may be omitted.

A trundle bed (or truckle bed) is a low, wheeled bed that is stored under a twin/single bed and can be rolled out for use by visitors or as just another bed.
A pop-up trundle bed can be raised to meet the height of the normal bed, effectively creating a wider sleeping surface when positioned side-by-side.
