Mattress
A mattress is a large, usually rectangular pad for supporting a person Lying (position), lying down, especially for sleeping. It is designed to be used as a bed, or on a bed frame as part of a bed. Mattresses may consist of a Quilting, 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 Elasticity (physics), elastic, such as an upholstered wood and wire box spring or a slatted foundation. Popular in Europe, a Divan (furniture), 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 na ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Platform Bed
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.

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 wooden or stone floors. 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. History and materials Before recycled cotton cloth was widely available in Japan, commoners used , stitched crinkled paper stuffed with fibers from beaten dry straw, cattails, or silk waste, on straw floor mats. Later, futons were made with patchwork recycled cotton, quilted together ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Box Spring
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 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. Purpose The purpose of a box-spring mainly lies in the trade-off between ventilating the bed through the bottom and the structural stability of the box-spring itself. Other Purposes The box-spring has a variety of advan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coir
Coir (), also called coconut fibre, is a natural fibre extracted from the outer husk of coconut, and used in products such as floor mats, doormats, brushes, and mattresses. Coir is the fibrous material found between the hard, internal shell and the outer coat of a coconut. Other uses of brown coir (made from ripe coconut) are in upholstery padding, sacking and horticulture. White coir, harvested from unripe coconuts, is used for making finer brushes, string, rope and fishing nets. It has the advantage of not sinking, so can be used in long lengths in deep water without the added weight dragging down boats and buoys. Coir must not be confused with coir pith, which is the powdery and spongy material resulting from the processing of the coir fibre. Coir fibre is locally named 'coprah' in some countries, adding to confusion. Pith is chemically similar to coir, but contains much shorter fibers. The name coco peat may refer either to coir or the pith or a mixture, as both have goo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bed Frame
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 mattress from sliding sideways, and it may include means of supporting a canopy above. There are several types of Bed Frames found around the globe. They are typically made of wood or metal. A bed frame includes head, foot, and side rails. The majority of double (full) beds and all queen- and king-sized beds necessitate a central support rail, often accompanied by additional feet that extend towards the floor for stability. The concept of a "bed frame" was initially introduced and referred to between 1805 and 1815. This foundational support system not only reinforces the structure of the bed but also ensures its durability and longevity, distributing weight evenly to prevent sagging and enhance overall comfort. Not all beds include frames: see bed base. Early bed frames Some of the earliest bed frames are known ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Horsehair
Horsehair is the long hair growing on the Mane (horse), manes and Tail (horse), tails of horses. It is used for various purposes, including upholstery, brushes, the Bow (music), bows of musical instruments, a hard-wearing Textile, fabric called haircloth, and for Lath and plaster, horsehair plaster, a wallcovering material formerly used in the construction industry and now found only in older buildings. Horsehair can be rough and knotted and dirty messes or very fine and flexible; mane hair is generally softer and shorter than tail hair. The texture of horsehair can be influenced by the breed and management of the horse, including natural conditions such as diet or climate. Processing may also affect quality and feel. Horsehair is a protein fiber that absorbs water slowly, but can be dyed or colored effectively using traditional dyes suitable for protein fibers. It can be felted, but not easily. Uses Horsehair fabrics are woven with wefts of tail hair from live horses and c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polyurethane Foam
Polyurethane foam is a solid polymeric foam based on polyurethane chemistry. As a specialist synthetic fibre, synthetic material with highly diverse applications, polyurethane foams are primarily used for thermal insulation and as a cushioning material in mattresses, upholstered furniture or as seating in vehicles. Its low density and thermal conductivity combined with its mechanical properties make them excellent thermal and sound insulators, as well as structural and comfort materials. Polyurethane foams are Thermosetting polymer, thermosetting polymers. They cannot be melted and reshaped after initially formed, because the chemical bonds between the molecules in the material are very strong and are not broken down by heating. Once cured and cooled, the material maintains its shape and properties.EURO-MOULDERS (2023) 'What is polyurethane foam' https://euromoulders.org/polyurethane-in-automobiles/what-is-polyurethane-foam/ Classification of polyurethane foams Polyurethane foa ...

Latex
Latex is an emulsion (stable dispersion) of polymer microparticles in water. Latices are found in nature, but synthetic latices are common as well. In nature, latex is found as a wikt:milky, milky fluid, which is present in 10% of all flowering plants (angiosperms) and in some Mushroom, mushrooms (especially species of ''Lactarius''). It is a complex emulsion that coagulation, coagulates on exposure to air, consisting of proteins, alkaloids, starches, sugars, Vegetable oil, oils, tannins, resins, and Natural gum, gums. It is usually exuded after tissue injury. In most plants, latex is white, but some have yellow, orange, or scarlet latex. Since the 17th century, latex has been used as a term for the fluid substance in plants, deriving from the Latin word for "liquid". It serves mainly as Antipredator adaptation, defense against Herbivore, herbivores and Fungivore, fungivores.Taskirawati, I. and Tuno, N., 2016Fungal defense against mycophagy in milk caps ''Science Report Kanazaw ...

Spring (device)
A spring is a device consisting of an Elasticity (physics), elastic but largely rigid material (typically metal) bent or molded into a form (especially a coil) that can return into shape after being compressed or extended. Springs can Energy storage, store energy when compressed. In everyday use, the term most often refers to coil springs, but there are many different spring designs. Modern springs are typically manufactured from spring steel. An example of a non-metallic spring is the Bow (weapon), bow, made traditionally of flexible Taxus baccata, yew wood, which when Bow draw, drawn stores energy to propel an arrow. When a conventional spring, without stiffness variability features, is compressed or stretched from its resting position, it exerts an opposing force approximately proportional to its change in length (this approximation breaks down for larger deflections). The ''rate'' or ''spring constant'' of a spring is the change in the force it exerts, divided by the cha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Malaria
Malaria is a Mosquito-borne disease, mosquito-borne infectious disease that affects vertebrates and ''Anopheles'' mosquitoes. Human malaria causes Signs and symptoms, symptoms that typically include fever, Fatigue (medical), fatigue, vomiting, and headaches. In severe cases, it can cause jaundice, Epileptic seizure, seizures, coma, or death. Symptoms usually begin 10 to 15 days after being bitten by an infected ''Anopheles'' mosquito. If not properly treated, people may have recurrences of the disease months later. In those who have recently survived an infection, reinfection usually causes milder symptoms. This partial Immunity (medical), resistance disappears over months to years if the person has no continuing exposure to malaria. The mosquitoes themselves are harmed by malaria, causing reduced lifespans in those infected by it. Malaria is caused by protozoa, single-celled microorganisms of the genus ''Plasmodium''. It is spread exclusively through bites of infected female ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
