From Wikipedia, the free encyclopedia
A bed (listen) is a piece of furniture or location primarily used as a place to sleep.
To make beds more comfortable, the top layer is frequently a mattress. Originally these were bags of straw for most people and filled with feathers for the wealthy.[citation needed] Eventually new fillings such as cotton and artificial fillers became common. In modern times most mattresses use springs, solid foam, latex, water, or air.
The second layer is the box spring. The box spring or "divan" is a large mattress-sized box containing wood and springs that provide additional support and suspension for the mattress.
The third layer is the bed frame. The bed frame lifts the mattress/mattress-box spring off the ground.
A dust ruffle, bed skirt, or valance sheet may be used to make the bed frame match the rest of the bedding.
For greater head support, most people use a pillow, placed at the top of a mattress. Also used is some form of covering blanket to provide warmth to the sleeper, often bed sheets, a quilt, or a duvet.
[edit] History
Early beds were little more than piles of straw or some other natural materials. An important change[citation needed] was raising them off the ground, to avoid drafts, dirt, and pests.
[edit] The Ancient World
The bed of Odysseus, a charpoy[1] woven of rope, plays a role in the Odyssey of Homer. A similar bed can be seen at the Museum of Welsh life at St. Fagans, Cardiff. Ancient Romans had various kinds of beds for repose. These included:
- lectus cubicularis, or chamber bed, for normal sleeping;
- lectus discubitorius, or table bed, on which they ate—for they ate while lying on their left side—there being usually three people to one bed, with the middle place accounted the most honorable position;
- lectus lucubratorius, for studying;
- and a lectus funebris, or emortualis, on which the dead were carried to the pyre.[2]
[edit] Bed sizes
Beds come in a wide array of shapes and sizes. Most countries have a standard set of four sizes of mattresses. While the Double size appears to be standard among English speaking countries, based on the imperial measurement of 4 ft 6 in by 6 ft 3 in, the sizes for other bed types tend to vary. The European sizes differ; they are based on the metric system.
A king-sized bed differs from the other sizes in implementation, as it is not common to have a king-sized box spring; rather, two smaller box-springs are used under a king-sized mattress. On a U.S. Standard or "Eastern" King, the box springs are identical in size to a Twin Extra-Long.
[edit] Standard sizes
Modern manufacturing conventions have resulted in a limited number of standard sizes of commercial bedding for mattresses and box springs. They vary by country of origin.

The sizes in the UK, other than the Double, vary compared to the U.S. sizes, being generally smaller. The U.S. Queen corresponds to UK King and King to Super King. The European or continental basic sizes are similar to the UK but have a set length of 2 metres. The denominations Queen, King and Super King are not used in continental Europe, and Double refers to 140cm or any higher width. Instead of these US/UK denominations, the bed width is given in centimeters.
These dimensions are for the mattress—the actual bed frame will be a little bigger in order to fully encompass and support the mattress. The thickness of the mattress may vary considerably.
Historically[attribution needed], Single referred to a bed size that was half the width of a Double, that is, approximately the width of one pillow. In Western nations, such beds have become quite rare, with a Twin bed becoming the standard for one-person sleeping.[citation needed] Without another common use for the term Single and with the term Double being widely used, Single has come to be another term for a twin bed in these places.
Portable cots are generally the size of original single beds.[citation needed]

[edit] Types of beds

There are many varieties of beds:
- An adjustable bed is a bed that can be adjusted to a number of different positions
- An air bed uses an air-inflated mattress, sometimes connected to an electric air pump and having firmness controls.
- A bassinet is a bed specifically for newborn infants.
- A box-bed is a bed having the form of a large box with wooden roof, sides, and ends, opening in front with two sliding panels or shutters; often used in cottages in Scotland: sometimes also applied to a bed arranged so as to fold up into a box.
- A brass bed, constructed from brass or brass-plated metal.
- A bunk is a bed used in a confined space.
- A bunk bed is two or more beds one atop the other. (See also: loft bed.)
- A captain's bed (also known as a chest bed or cabin bed) is a platform bed with drawers and storage compartments built in underneath.
- An infant's bed (also crib or cot) is a small bed specifically for babies and infants.
- A camp bed (also cot) is a simple, temporary, portable bed used by armies and large organizations in times of crisis.
- A canopy bed is similar to a four poster bed, but the posts usually extend higher and are adorned or draped with cloth, sometimes completely enclosing the bed.
- A daybed is a couch that is used as a seat by day and as a bed by night.
- A futon is a traditional style of Japanese bed that is also available in a larger Western style.
- A four poster bed is a bed with four posts, one in each corner, that support a tester.
- A hammock is a piece of suspended fabric.
- A hideaway bed, invented by Sarah E. Goode in response to the needs of apartment-dwellers, folds up into another piece of furniture, such as a shelf or desk, when not in use.
- A hospital bed is specifically designed to facilitate convalescence, traditionally in a hospital or nursing facility, but increasingly in other settings, such as a private residence. Modern hospital beds commonly have wheels to assist in moderate relocation, but they are larger and generally more permanently placed than a gurney. The hospital bed is also a common unit of measurement for the capacity of any type of inpatient medical facility, though it is just as common to shorten the term to bed in that usage.
- An iron bed, developed in the 1850s, is constructed of iron and steel.
- A Manjaa is a traditional Punjabi bed made of tied ropes bordered by a wooden frame.
- A Murphy bed or wallbed is a bed that can hinge into a wall or cabinet to save space.
- A pallet is a thin, lightweight mattress.
- A platform bed is a mattress resting on a solid, flat raised surface, either free-standing or part of the structure of the room.
- A roll-away bed (or cot) is a bed whose frame folds in half and rolls in order to be more easily stored and moved.
- A sofabed is a bed that is stored inside a sofa.
- A state bed developed in Early Modern Europe from a hieratic canopy of state.
- A trundle bed or truckle bed is a bed usually stored beneath a twin bed.
- A vibrating bed is typically a coin-operated novelty found in a vintage motel. For a fee, the mattress vibrates for a duration of time.
- A waterbed is a bed/mattress combination where the mattress is filled with water.
[edit] Bed frames
Bed frames, also called bed steads, are made of wood or metal. The frame is made up of head, foot, and side rails. For heavy duty or larger frames (such as for queen- and king-sized beds), the bed frame also includes a center support rail. These rails are assembled to create a box for the mattress or mattress/box spring to sit on.
Types of bed frames are:
- platform - typically used without a box spring
- captain - has drawers beneath the frame to make use of the space between the floor and the bed frame
- waterbed - a heavy-duty frame built specifically to support the weight of the water in the mattress
Though not truly parts of a bed frame, many people[attribution needed] include headboards, footboards, and bed rails in their definition of bed frames. Headboards and footboards can be wood or metal. They can be stained, painted, or covered in fabric or leather.
Bed rails are made of wood or metal and are attached to a headboard and footboard. Wooden slats are placed perpendicular to the bed rails to support the mattress/mattress box spring.
