Headboard (furniture)
The headboard is a piece of furniture that attaches to the head of a bed A bed is an item 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 .... Historically, they served to isolate sleepers from drafts and cold in less insulated buildings, and thus were made of wood, which is less thermally conductive than stone or brick. Constructed to create space from the wall (via thicker end pillars) they allowed falling colder air to sink to the floor rather than onto the bed. Today, in better heated and insulated residences, headboards chiefly serve an aesthetic function, as well as minor practical functions, such as keeping pillows from falling off the bed. They may include storage space for books and personal items, and conveniences such as lights and telephone. Those of hospital beds may incorporate cri ...

Wooden Headboard
Wood is a porous and fibrous structural tissue found in the stems and roots of trees and other woody plants. It is an organic materiala natural composite of cellulose fibers that are strong in tension and embedded in a matrix of lignin that resists compression. Wood is sometimes defined as only the secondary xylem in the stems of trees, or it is defined more broadly to include the same type of tissue elsewhere such as in the roots of trees or shrubs. In a living tree it performs a support function, enabling woody plants to grow large or to stand up by themselves. It also conveys water and nutrients between the leaves, other growing tissues, and the roots. Wood may also refer to other plant materials with comparable properties, and to material engineered from wood, or woodchips or fiber. Wood has been used for thousands of years for fuel, as a construction material, for making tools and weapons, furniture and paper. More recently it emerged as a feedstock for the production ...

Furniture
Furniture refers to movable objects intended to support various human activities such as seating (e.g., stools, chairs, and sofas), eating (tables), storing items, eating and/or working with an item, and sleeping (e.g., beds and hammocks). Furniture is also used to hold objects at a convenient height for work (as horizontal surfaces above the ground, such as tables and desks), or to store things (e.g., cupboards, shelves, and drawers). Furniture can be a product of design and can be considered a form of decorative art. In addition to furniture's functional role, it can serve a symbolic or religious purpose. It can be made from a vast multitude of materials, including metal, plastic, and wood. Furniture can be made using a variety of woodworking joints which often reflects the local culture. People have been using natural objects, such as tree stumps, rocks and moss, as furniture since the beginning of human civilization and continues today in some households/campsites. Ar ...

Thermal Conduction
Conduction is the process by which heat is transferred from the hotter end to the colder end of an object. The ability of the object to conduct heat is known as its ''thermal conductivity'', and is denoted . Heat spontaneously flows along a temperature gradient (i.e. from a hotter body to a colder body). For example, heat is conducted from the hotplate of an electric stove to the bottom of a saucepan in contact with it. In the absence of an opposing external driving energy source, within a body or between bodies, temperature differences decay over time, and thermal equilibrium is approached, temperature becoming more uniform. In conduction, the heat flow is within and through the body itself. In contrast, in heat transfer by thermal radiation, the transfer is often between bodies, which may be separated spatially. Heat can also be transferred by a combination of conduction and radiation. In solids, conduction is mediated by the combination of vibrations and collisions of molecul ...

Footboard (furniture)
A bed frame or bedstead is the part of a bed used to position the bed base, the flat part which in turn directly supports the mattress(es). The frame may also stop the matresses from sliding sideways, and it may include means of supporting a canopy above. Bed frames are typically made of wood or metal. A bed frame includes head, foot, and side rails. Most double (full) sized beds, along with all queen and king size beds, require some type of center support rail, typically also with extra feet extending down to the floor. The term "bed frame" was first used in 1805-1815. Not all beds include frames; see bed base. Brass beds Brass beds are beds in which the headboard and footboard are made of brass; the frame rails are usually made of steel. Brass beds can be made of 100 per cent brass or of metals that have been brass-plated. The brass used in making brass beds is usually 70 per cent copper and 30 per cent zinc. The ratio of metals may vary between manufacturers. Brass beds we ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
