Mattress Topper
A mattress pad, mattress topper, or underpad is designed to lie atop a mattress. Made from a variety of materials such as wool, cotton, memory foam, feather or latex, its function is to provide an extra layer of comfort, especially when the existing mattress is worn or uncomfortable. Physically, it is a thin mattress, usually thick. Stand-alone mattresses of this size exist, including futons, and floor beds. Similarly, traditional European beds were made of a stack of mattresses of this size. In contrast, mattress toppers are usually sold for use on top of boxsprings (secured with straps or elasticated cloth corners). They are used to extend the life of the more-expensive boxspring, make a bed warmer or cooler (with airflow, or heat-conductive materials), make a firm bed softer, and for travel and dorms, as they are portable, especially if they are low-density. Like a mattress protector/mattress pad/mattress cover (a thin, generally unpadded layer not designed to improve comf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mattress Protector
A mattress protector (also mattress cover, mattress pad may mean this or a mattress topper) is an item of removable bedding that sits on top of, or encases, a mattress to protect it. Some mattress protectors also provide protection to the person sleeping on the mattress from allergens and irritants such as dust mites, bed bugs, mold, and dead skin (like dandruff). Protecting the mattress Although the surface of a mattress can be cleaned with a vacuum cleaner, it is very difficult to completely clean most standard mattresses. An unprotected mattress can become marked or stained quite quickly as perspiration produced throughout the night easily passes through a standard cloth sheet and creates a characteristic yellowish-brown tidemark where it's absorbed into the upper surface of the mattress. Mattresses are also susceptible to many other contaminants. The simplest form of a mattress protector is a lightly quilted fitted sheet. It provides minimal protection against liquids ...

Mattress Topper Atop A Boxspring Mattress
A mattress is a large, usually rectangular pad for supporting a lying person. It is designed to be used as a bed, or on a bed frame as part of a bed. Mattresses may consist of a quilted or similarly fastened case, usually of heavy cloth, containing materials such as hair, straw, cotton, foam rubber, or a framework of metal springs. Mattresses may also be filled with air or water. Mattresses are usually placed on top of a bed base which may be solid, as in the case of a platform bed, or elastic, such as an upholstered wood and wire box spring or a slatted foundation. Popular in Europe, a divan incorporates both mattress and foundation in a single upholstered, footed unit. Divans have at least one innerspring layer as well as cushioning materials. They may be supplied with a secondary mattress or a removable "topper". Mattresses may also be filled with air or water, or a variety of natural fibers, such as in futons.

Futon
A is a traditional Japanese style of bedding. A complete futon set consists of a and a . Both elements of a futon bedding set are pliable enough to be folded and stored away in a large during the day. This allows a room to serve as a bedroom at night, but serve other purposes during the day. Traditionally, futons are used on tatami, a type of mat used as a flooring material. It also provides a softer base than, say, a floor of wood or stone. Futons must be aired regularly to prevent mold from developing, and to keep the futon free of mites. Throughout Japan, futons can commonly be seen hanging over balconies, airing in the sun. Futon dryers may be used by those unable to hang out their futon.

Bed Base
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 shorter than the measurements of a mattress. In hot climates, mattress may be omitted.

Tick Mattress
A tick mattress, bed tick or tick is a large bag made of strong, stiff, tightly-woven material (ticking). This is then filled to make a mattress, with material such as straw, chaff, horsehair, coarse wool or down feathers,Dictionnaire de l'ameublement et de la décoration depuis le XIIIe siècle jusqu'à nos jours, Havard, Henry, 1838-1921 and less commonly, leaves, grass, reeds, bracken, or seaweed. The whole stuffed mattress may also, more loosely, be called a tick. The tick mattress may then be sewn through to hold the filling in place, or the unsecured filling could be shaken and smoothed as the beds were aired each morning. A straw-filled bed tick is called a paillasse, palliasse, or pallet, and these terms may also be used for bed ticks with other fillings. A tick filled with flock (loose, unspun fibers, traditionally of cotton or wool) is called a flockbed. A feather-filled tick is called a featherbed, and a down-filled one a downbed; these can also be used above the sleepe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boxspring
Queen size box-spring on metal bed frame 8-way hand-tied box spring 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 that is placed on it. Working together, the box-spring and mattress (with 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. Purpose The purpose of a box-spring mainly lies in the trade-off between ventilating the bed through the bottom and structural stability of the box-spring itself.

Ticking
Ticking is a type of cloth, traditionally a tightly-woven cotton or linen textile. It is traditionally used to cover tick mattresses and bed pillows. The tight weave makes it more durable and hinders the stuffing (straw, chaff, hair, down feathers, etc.) from poking through the fabric. To make it even tighter, ticking could be waxed, soaped, or starched. Tick materials designed to hold foam may be knit, or more porous. In English-speaking countries ticking commonly has a striped design, in muted colors such as brown, grey or blue, and occasionally red or yellow, against a plain, neutral background. Although traditionally used for mattresses and pillows, the material has found other uses, such as serving as a backing for quilts, coverlets, and other bedding. It is sometimes woven with a twill weave. Ticking is no longer restricted to a utility fabric and has found uses in interior decorating styles intending to evoke a homespun or industrial aesthetic. Modern uses for ticking incl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Viscoelasticity
In materials science and continuum mechanics, viscoelasticity is the property of materials that exhibit both viscous and elastic characteristics when undergoing deformation. Viscous materials, like water, resist shear flow and strain linearly with time when a stress is applied. Elastic materials strain when stretched and immediately return to their original state once the stress is removed. Viscoelastic materials have elements of both of these properties and, as such, exhibit time-dependent strain. Whereas elasticity is usually the result of bond stretching along crystallographic planes in an ordered solid, viscosity is the result of the diffusion of atoms or molecules inside an amorphous material.Meyers and Chawla (1999): "Mechanical Behavior of Materials", 98-103. Background In the nineteenth century, physicists such as Maxwell, Boltzmann, and Kelvin researched and experimented with creep and recovery of glasses, metals, and rubbers. Viscoelasticity was further examined in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Memory Foam
Memory foam consists mainly of polyurethane with additional chemicals that increase its viscosity and density. It is often referred to as "viscoelastic" polyurethane foam, or low-resilience polyurethane foam (LRPu). The foam bubbles or ‘cells’ are open, effectively creating a matrix through which air can move. Higher-density memory foam softens in reaction to body heat, allowing it to mold to a warm body in a few minutes. Newer foams may recover their original shape more quickly. Mechanics Memory foam derives its viscoelastic properties from several effects, due to the material's internal structure. The network effect is the force working to restore the foam's structure when it is deformed. This effect is generated by the deformed porous material pushing outwards to restore its structure against an applied pressure. Three effects work against the network effect, slowing the regeneration of the foam's original structure: * The pneumatic effect, caused by the time it takes air ...

Electric Blanket
An electric blanket is a blanket that contains integrated electrical heating wires. Types include underblankets, overblankets, throws, and duvets. An electric ''underblanket'' is placed above the mattress and below the bottom bed sheet. This is the most common type in the UK and Commonwealth countries, where it is known by default as an "electric blanket"; in the U.S. and Canada, where it is less common, it is called an electric heated mattress pad. An electric ''overblanket'' is placed above the top bed sheet, and is the most common type in the U.S. and Canada, where it is called an "electric blanket". Electric blankets usually have a control unit that adjusts the amount of heat the blanket produces by pulsing current at different intervals. Blankets for two-person beds often have separate controls for each side of the bed. The electric blanket may be used to pre-heat the bed before use or to keep the occupant warm while in bed. Electric blankets use between 15 and 115 watts ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
