An air mattress is an inflatable mattress/sleeping pad. Due to its buoyancy, it is often used as a water toy/flotation device, in some countries, including the UK, is called a lilo. An air mattress known as an airbed or a blow-up bed, is an inflatable mattress, the majority of which are made of polyvinyl chloride, although developed textile-reinforced urethane plastic or rubber versions exist; the deflated mattress can be rolled up or folded and carried or stored easily, making them a popular choice for camping trips and for temporary bedding at home for guests. They are inflated either orally by blowing into a valve, or with a manual foot-powered or more inflated via an electric pump; some are automatically inflating just by opening the valve. The three main categories for use of air mattresses are camping, temporary home use and full-time permanent use; some air mattresses are designed to perform both functions while others are designed for one purpose alone. Other air mattresses are designed in shapes with wheel well cutouts intended for use in vehicles such as pickup trucks or SUVs.
Lightweight, reduced-size and reduced-thickness air mattresses intended for camping and backpacking are sometimes called sleeping pads when a layer of foam insulation is added under the air chambers. Better quality air chambers, that are designed for permanent use in the home, are constructed of vulcanized rubber, covered in canvas or of polyurethane; these chamber are installed into a cloth shell or tick. Permanent air beds will look like conventional beds with the exception of having a hose or hoses coming out of the head of the bed; these hoses will be connected to an air inflation device, with two outlet valves, that will have a remote control so that each person can adjust the firmness of his or her side to his/her own exact needs. The firmness can be adjusted up or down, on the remote. A USA government safety agency has warned against letting infants sleep on air mattresses, because they can be too soft and suffocate smaller children within folds or while entrapped between the mattress and the bed base.
Additionally there have been several recent governmental studies and regulations enacted due to the poisonous nature of the phthalate plasticizers contained within most PVC vinyl air beds and other soft vinyl products. The European Union has made similar efforts to prevent the use of vinyl materials in toys and bedding. Larger, more elaborate air mattresses have come on the market in recent years that are intended for guest use or as permanent beds in the bedroom. Bed sizes for temporary air beds range from twin to king size, but few guest bed manufacturers offer king size as most guest air beds are sold outside the United States where king-size mattresses are not standard. Most permanent air beds use easy-to-find conventional sheets and bedding. California King sheets and bedding may be more difficult to find as this size was conceived for the waterbed industry. Raised guest or temporary beds are raised off the ground to keep users away from the floor and offer a more traditional mattress experience.
Though'raised' air beds are off the ground, they are not designed for full-time use, as the base of the bed is an air chamber and not a solid foundation. Air mattresses can improve the quality of life for people who suffer with back pain. Having the ability to adjust the firmness of a mattress to accommodate different body shapes and weights, can be a factor in the healing process. Air mattresses are sometimes used to protect bedridden people from pressure sores, which can create life-threatening ulcers. Additionally, air mattresses manufactured without the use of materials that may release VOCs or other toxic compounds from the manufacturing process are available; the term air mattress may refer to a certain inflatable swimming pool or beach toy, which has an air-sac "pillow" and several tubes running its length. Called a "lilo", "pool air mat", "air mat", "pool lounge", or "float mat", it is used to recline on the water surface; the Li-Lo trademark for a rubberised material products was registered in UK on 19 Apr 1944 and in the USA on 25 Sep 1947 by P. B.
Cow and Co Ltd. An inflatable air mattress for recreational use was advertised as one of the Li-Lo brand of products at the British Industries Fair in London 1949. Although it bears some resemblance to an air mattress, it is not built as and may not reliably stay inflated all night long, making it impractical for use as a bed. Permanent use adjustable-firmness "airbeds" became popular after market leader Select Comfort began a major marketing campaign around 2001; the original airbed was manufactured by Comfortaire in 1981, purchased by Select Comfort, in January 2013 for $15.5m. Select Comfort announced on March 30, 2017 that they were ceasing all third party retail sales, of the Comfortaire Line of products shutting down the Comfortaire Brand. Other manufacturers include Boyd Specialty, InnoMax, American National. Less expensive airbeds used for camping or guests include the Aerobed, sold by Jarden subsidiary The Coleman Company.

Kyushu Institute of Technology
Kyushu Institute of Technology is one of the 87 national universities in Japan. Located in Fukuoka Prefecture on the island of Kyushu, it is dedicated to education and research in the fields of science and technology, it is abbreviated to KIT and sometimes to Kyutech. The founder was Matsumoto Kenjiro, second son of Yasukawa Keiichiro, the links with the Yaskawa Electric Corporation remain strong to this day; the centenary of the opening of the Tobata campus is being celebrated in 2009, with Founder's Day on May 28, 2009. One of its famous alumnus is the severe storms researcher Tetsuya "Ted" Fujita, he graduated in 1943 and was an associate professor until 1953 when he was invited to the University of Chicago. The university was granted government permission to be founded in 1907 as a private training school for engineers called Meiji Senmon Gakkō, toward the end of the Meiji period; the first campus opened its doors in Tobata in 1909, the centenary of the university is therefore being celebrated in 2009.
KIT became a Japanese national university on May 31, 1949 and has, since April 1, 2004, been incorporated as a national university corporation under a new law that applies to all national universities. Despite the incorporation, which has led to increased financial independence and autonomy, KIT is still quite controlled in many respects by the Japanese Ministry of Education. In 1995, the Satellite Venture Business Laboratory was opened at Tobata campus; the first school building of Meiji Senmon Gakko was made wholly of wood and designed by Tatsuno Kingo. There is a 1/50th scale model of the building on display in the university archives on Tobata campus; the first president of KIT, Yamakawa Kenjiro who studied at Yale University declared that the aim of the school was to produce "gentlemen well versed in technological skills". Nowadays the university aims to produce both ladies and gentlemen with these skills, enjoys a high reputation with employers. Founder's day is May 28, it coincides deliberately with the Battle of Tsushima of May 27 and May 28, 1905, the decisive naval battle in the Russo-Japanese War.
Admiral Tōgō Heihachirō once visited KIT, his visit is commemorated in the school's archives, as is that of Okuma Shigenobu. KIT has three campuses. Two of these are in Kitakyushu and one is in Iizuka. All three are in Kyushu. Faculty of Engineering, Graduate School of Engineering; this is the oldest campus, opened in 1909. It was designed by Tatsuno Kingo, it had three departments: Mining and Mechanical Engineering. Faculty of Computer Science and Systems Engineering, Graduate School of Computer Science and Systems Engineering; this is the second campus, established in 1986. The first students were admitted in 1987. Graduate School of Life Science and Systems Engineering; this is the newest campus, established in April 2001. KIT has partnership agreements with several overseas universities, including the Universiti Tunku Abdul Rahman, University of Surrey, Old Dominion University, the University of Texas at El Paso.

An infant bed is a small bed for infants and young children. Infant beds are a recent development intended to contain a child capable of standing; the cage-like design of infant beds restricts the child to the bed. Between one and two years of age, children are able to climb out and are moved to a toddler bed to prevent an injurious fall while escaping the bed. Infant beds are more common in Western countries, employed by the majority of parents as an alternative to sharing a bed; the name "crib" was used to describe high-sided child's bed. It derives from the Old English word "cribb" which means stall, it wasn't until the 19th century that infant beds developed from bassinettes, acquiring a role of keeping the child in their bed. The development of a distinction between infant beds and bassinettes was natural because it was "considered vital that the child's bed be raised off the ground." This was due to a perception of noxious fumes below knee level, explosive vapours near the ceiling, with good air in between.
Once children's beds were raised off the ground the role of the sides changed from a convenience to a safety feature. It was recognised that once children learn to stand they may be able to get out of a bed with low sides. According to an expert of the time, infant beds were used. One side was hinged to open the enclosure, a function fulfilled in modern infant beds with a dropside. With the hinge side lowered, the bed could be moved on casters, they could be moved right up to the carer's bed when needed. Iron beds were developed in 17th century Italy to address concerns about bed bug infestation and moths; this new application was extended to children's beds - a rockable iron bassinette has been dated to 1620-1640. Proponents promoted the supposed health benefits of iron beds. Infant beds constructed from metal became popular during the half of the 19th century. Infant beds constructed from iron with mesh or chain sides were common. Childcare experts gave iron beds their approval because it was hygienic material and could not "habour vermin", of which bed bug infestation and moths were cited concerns.
Painted with a white vitreous enamel manufacturers working with wood continued to paint in the now traditional white. Since 1938, babies in Finland have slept in cardboard boxes with a mattress in the bottom, which are distributed to expectant mothers as a "maternity package" containing baby supplies; as an example of improving safety of infant bed designs, the U. S. Consumer Product Safety Commission has set standards for infant beds sold since 1973. Since this time U. S. annual deaths attributed to infant beds reducing from 200 to 50, injury rates now at 8,000 per year. Many of these injuries are attributed to the 25 million infant beds manufactured prior to the progressively refined safety standards, yet still in use. Infant beds are designed to restrict the baby to the bed; the sides are too high for a baby to provide no footholds. Technical standards for infant beds include considerations such as the materials used and preventing hand and head entrapment. Standards for infant beds have been specified in Australia and New Zealand, the United States and internationally.
Design standards all identify and address four broad hazards: Falls To prevent injuries such as concussion and bone fractures from falls when trying to climb out, footholds are not permitted. Minimum cot side heights are defined for various mattress positions. Strangulation Infants can become trapped and strangled if their clothing gets caught on parts of a cot that stick out, or if their head becomes trapped between gaps. Neither gaps large enough for a child's head nor protrusions are permitted. Suffocation Babies lack the motor skills or strength to turn their heads should they roll into something that obstructs their breathing, they can become trapped and suffocate if they fall into gaps created by ill-fitting or additional mattresses. Babies can suffocate if the mattress is too soft. Entrapment Infants can suffer injuries to their legs if they become trapped between gaps. Gaps small enough for a limb to become trapped are not permitted; some older cribs contained a drop gate, a side which lowers to ease the process of putting the child into the bed, but can be raised again to restore the integrity of the enclosure.
However, assembly problems and malfunctioning hardware on drop gates can cause the formation of gaps, which have been attributed to infant deaths and other major injuries. In June 2011, the United States implemented new safety standards requiring all infant beds manufactured and sold in the country to have fixed sides. In June 2016, Canada implemented a similar ban on the sale, importation, or distribution of any infant bed containing drop sides effective December 29, 2016. Infant beds can be portable. In their portable form the beds don't feature a dropside, portability factors are emphasised. Portacots are made from plastics, are smaller and fold into a compact package. Rather than bars, they will have breathable mesh sides with an aperture too small for any finger to fit into. Standards for folding infant beds exist for Australia and New Zealand and inte
A hospital bed or hospital cot is a bed specially designed for hospitalized patients or others in need of some form of health care. These beds have special features both for the comfort and well-being of the patient and for the convenience of health care workers. Common features include adjustable height for the entire bed, the head, the feet, adjustable side rails, electronic buttons to operate both the bed and other nearby electronic devices. Hospital beds and other similar types of beds such as nursing care beds are used not only in hospitals, but in other health care facilities and settings, such as nursing homes, assisted living facilities, outpatient clinics, in home health care. While the term "hospital bed" can refer to the actual bed, the term "bed" is used to describe the amount of space in a health care facility, as the capacity for the number of patients at the facility is measured in available "beds." Beds with adjustable side rails first appeared in Britain some time between 1815 and 1825.
In 1874 the mattress company Andrew Wuest and Son, Ohio, registered a patent for a type of mattress frame with a hinged head that could be elevated, a predecessor of the modern day hospital bed. The modern 3-segment adjustable hospital bed was invented by Willis Dew Gatch, chair of the Department of Surgery at the Indiana University School of Medicine, in the early 20th century; this type of bed is sometimes referred to as the Gatch Bed. The modern push-button hospital bed was invented in 1945, it included a built-in toilet in hopes of eliminating the bedpan. Wheels enable easy movement of the bed, either within parts of the facility in which they are located, or within the room. Sometimes movement of the bed a few inches to a few feet may be necessary in patient care. Wheels are lockable. For safety, wheels can be locked when transferring the patient out of the bed. Beds can be raised and lowered at the head and their entire height. While on older beds this is done with cranks found at the foot of the bed, on modern beds this feature is electronic.
Today, while a electric bed has many features that are electronic, a semi-electric bed has two motors, one to raise the head, the other to raise the foot. Raising the head can provide some benefits to the staff, or both; the Fowler's position is used for sitting the patient upright for feeding or certain other activities, or in some patients, can ease breathing, or may be beneficial to the patient for other reasons. Raising the feet can help ease movement of the patient toward the headboard and may be necessary for certain conditions. Raising and lowering the height of the bed can help bring the bed to a comfortable level for the patient to get in and out of bed, or for caregivers to work with the patient. Beds have side rails that can be lowered; these rails, which serve as protection for the patient and sometimes can make the patient feel more secure, can include the buttons used for their operation by staff and patients to move the bed, call the nurse, or control the television. There are a variety of different types of side rails to serve different purposes.
While some are to prevent patient falls, others have equipment that can aid the patient themself without physically confining the patient to bed. Side rails, if not built properly, can be of risk for patient entrapment. In the United States, more than 300 deaths were reported as a result of this between 1985 and 2004; as a result, the Food and Drug Administration has set guidelines regarding the safety of side rails. In some cases, use of the rails may require a physician's order as rails may be considered a form of medical restraint; some advanced beds are equipped with columns. Such tilting can help prevent pressure ulcers for the patient, help caregivers to do their daily tasks with less of a risk of back injuries. Many modern hospital beds are able to feature a bed exit alarm whereby a pressure pad on or in the mattress arms an audible alert when a weight such as a patient is placed on it, activating the full alarm once this weight is removed; this is helpful to hospital staff or caregivers monitoring any number of patients from a distance as the alarm will trigger in the event of a patient falling out of the bed or wandering off unsupervised.
This alarm can be emitted from the bed itself or connected to the nurse call bell/light or hospital phone/paging system. Some beds can feature a multi-zone bed exit alarm which can alert the staff when the patient start moving in the bed and before the actual exit, necessary for some cases. In the event of the bed occupant requiring cardiopulmonary resuscitation, some hospital beds offer a CPR function in the form of a button or lever which when activated flatten the bed platform and put it in lowest height and deflates and flattens the bed's air mattress creating a flat hard surface necessary for effective CPR administration. Many specialist hospital beds are produced in order to treat different injuries; these include standing beds. These are used to treat back and spinal injuries as well as severe trauma. A hospital bed can cost over $1000.00 USD. Other costs are associated with bariatric heavy duty models that offer extra width. Hospital beds can make a patient's spine more rounded because a patient who sits up a lot, such as
A bed frame or bedstead is the part of a bed used to position the mattress and base, may include means of supporting a canopy above. Bed frames are made of wood or metal. A bed frame includes head and side rails, it may include slats to support the mattress, in which case a separate base is not necessary, as in a platform bed. Most double sized beds, along with all queen and king size beds, require some type of center support rail also with extra feet extending down to the floor; the term "bed frame" was first used in 1805-1815. Brass beds are beds in which the footboard are made of brass. Brass beds can be made of metals that have been brass-plated; the brass used in making brass beds is 70 per cent copper and 30 per cent zinc. The ratio of metals may vary between manufacturers. Brass beds were simple and plain. Throughout the centuries, designs have become elaborate and can contain extensive ornamentation such as porcelain finials; some brass bed styles include traditional, Art Deco, transitional and contemporary.
Iron beds are beds in which the footboard are made of iron. Iron beds were developed in 17th century Italy to address concerns about infestation by bed bugs and moths. An iron cradle has been dated to 1620-1640. From the start of their production in the 1850s until World War I, iron beds were handmade; the manufacturing process included hand pouring and polishing intricately detailed casting and hand applying finishes. In the many small foundries of the time that employed only a handful of employees, it could take days to produce a single bed. After the end of World War I, the mass-production methods used for wartime affected the iron industry as well; the handmade quality gave way to cost-effective mass production. Today's iron beds are constructed of heavy-gauge steel tubing and solid bar stock. All iron beds now have a beech wood sprung slatted base in a steel framework which gives support to all types of mattresses; some wooden-based beds have drawers. The bed frame is a wooden box with a hole cut out with drawers underneath.

The furry fandom is a subculture interested in anthropomorphic animal characters with human personalities and characteristics. Examples of anthropomorphic attributes include exhibiting human intelligence and facial expressions, walking on two legs, wearing clothes; the term "furry fandom" is used to refer to the community of people who gather on the Internet and at furry conventions. According to fandom historian Fred Patten, the concept of furry originated at a science fiction convention in 1980, when a character drawing from Steve Gallacci’s Albedo Anthropomorphics started a discussion of anthropomorphic characters in science fiction novels; this led to the formation of a discussion group that met at science fiction conventions and comics conventions. The specific term furry fandom was being used in fanzines as early as 1983, had become the standard name for the genre by the mid-1990s, when it was defined as "the organized appreciation and dissemination of art and prose regarding'Furries', or fictional mammalian anthropomorphic characters".
However, fans consider the origins of furry fandom to be much earlier, with fictional works such as Kimba, The White Lion released in 1965, Richard Adams' novel Watership Down, published in 1972, as well as Disney's Robin Hood as oft-cited examples. Internet newsgroup discussion in the 1990s created some separation between fans of "funny animal" characters and furry characters, meant to avoid the baggage, associated with the term "furry". During the 1980s, furry fans began to publish fanzines, developing a diverse social group that began to schedule social gatherings. By 1989, there was sufficient interest to stage the first furry convention, it was called Confurence 0, was held at the Holiday Inn Bristol Plaza in Costa Mesa, California. The next decade, the Internet became accessible to the general population and became the most popular means for furry fans to socialize; the newsgroup alt.fan.furry was created in November 1990, virtual environments such as MUCKs became popular places on the Internet for fans to meet and communicate.
The furry fandom is male-dominated, with surveys reporting around 80% male respondents. Allegorical novels, including works of both science fiction and fantasy, cartoons featuring anthropomorphic animals are cited as the earliest inspiration for the fandom. A survey conducted in 2007 suggested that, when compared with a non-furry control group, a higher proportion of those self-identifying as furries liked cartoons "a great deal" as children and recalled watching them more as well as being more to enjoy works of science fiction than those outside of the community. According to a survey from 2008, most furries believe that visual art, conventions and online communities are important to the fandom. Fans with craft skills create their own plush toys, sometimes referred to as plushies, build elaborate costumes called fursuits, which are worn for fun or to participate in parades, convention masquerades, dances, or fund-raising charity events. Fursuits range from designs featuring simple construction and resembling sports mascots to those with more sophisticated features that include moving jaw mechanisms, animatronic parts, prosthetic makeup, other features.
Fursuits range in price from $500, for mascot-like designs, to an upwards of $10,000 for models incorporating animatronics. While about 80% of furries do not own a full fursuit citing their expensive cost as the decisive factor, a majority of them hold positive feelings towards fursuiters and the conventions in which they participate; some fans may wear "partial" suits consisting of ears and a tail, or a head, a tail. Furry fans pursue puppetry, recording videos and performing live shows such as Rapid T. Rabbit and Friends and the Funday PawPet Show, create furry accessories, such as ears or tails. Anthropomorphic animal characters created by furry fans, known as fursonas, are used for role-playing in MUDs, on internet forums, or on electronic mailing lists. A variety of species are employed as the basis of these personas, although many furry fans choose to identify themselves with carnivorans; the longest-running online furry role-playing environment is FurryMUCK, established in 1990. Many furry fans had their first exposure to the fandom come from multiplayer online role-playing games.
Another popular online furry social game is called Furcadia, created by Dragon's Eye Productions. There are several furry-themed areas and communities in the virtual world Second Life. Sufficient interest and membership has enabled the creation of many furry conventions in North America and Europe. A furry convention is for the fans get together to buy and sell artwork, participate in workshops, wear costumes, socialize; the world's largest furry convention, Anthrocon with more than 5,861 participants, held annually in Pittsburgh in June, was estimated to have generated $3 million to Pittsburgh's economy in 2008. Another convention, Further Confusion, held in San Jose each January follows Anthrocon in scale and attendance. US$470,000 was raised in conventions for charity from 2000–9; the first known furry convention, ConFurence, is no longer held. A University of California, Davis survey suggested that about 40% of furries had attended at least one furry convention; the Internet contains a multitude of furry websites and online communities, such as art community websites Fur Affinity, Inkbunny, SoFurry and Weasyl.
A hammock is a sling made of fabric, rope, or netting, suspended between two or more points, used for swinging, sleeping, or resting. It consists of one or more cloth panels, or a woven network of twine or thin rope stretched with ropes between two firm anchor points such as trees or posts. Hammocks were developed by native inhabitants of South America for sleeping, they were used aboard ships by sailors to enable comfort and maximize available space, by explorers or soldiers travelling in wooded regions. In the 1920s, parents throughout North America used fabric hammocks to contain babies just learning to crawl. Today they are popular around the world for relaxation; the hammock is seen as a symbol of summer, leisure and simple, easy living. Spanish colonists noted the use of the hammock by Native Americans in the West Indies, at the time of the Spanish conquest. Columbus, in the narrative of his first voyage, says: “A great many Indians in canoes came to the ship to-day for the purpose of bartering their cotton, hamacas, or nets, in which they sleep.”The word comes from a Taíno culture Arawakan word meaning "stretch of cloth" from the Arawak root -maka.
Early hammocks were woven out of tree bark, this material was replaced by sisal fibers because it was more abundant. One of the reasons that hammocks became popular in Central and South America was their ability to provide safety from disease transmission, insect stings, or animal bites. By suspending their beds above ground, inhabitants were better protected from snakes, biting ants, other harmful creatures; the origin of the hammock in the Americas is obscured in English-language sources from the late 18th century onward. Samuel Johnson claimed; this etymology was soon debunked, 19th-century sources attributed the invention to the Athenian politician Alcibiades. This was inferred from Plutarch, who wrote that Alcibiades had his galley bed hung from ropes, but did not describe it as a net or sling. A few European sources mention the historical use of cloth slings as carriage seats, but not as regular beds. Around 1590, hammocks were adopted for use in sailing ships. Aboard ship, hammocks were employed for sailors sleeping on the gun decks of warships, where limited space prevented the installation of permanent bunks.
Since a slung hammock moves in concert with the motion of the vessel, the occupant is not at a risk of being thrown onto the deck during swells or rough seas. A hammock provides more comfortable sleep than a bunk or a berth while at sea since the sleeper always stays well balanced, irrespective of the motion of the vessel. Prior to the adoption of naval hammocks, sailors would be injured or killed as they fell off their berths or rolled on the decks on heavy seas; the sides of traditional canvas naval hammocks wrap around the sleeper like a cocoon, making an inadvertent fall impossible. If suitably packed, they could be used as emergency flotation devices. Many sailors in the Royal Navy, during the 1950s at least, used a spreader – a length of wood with a V cut in each end to engage the second hammock string on each side; the first string was set up more than the others so that it raised a protective lip along each side to keep out drafts and prevent the sleeper being thrown out. A narrow mattress was issued which protected the user from cold from below.
In addition naval hammocks could be rolled and stowed in an out of the way place or in nets along the gunwale as additional protection during battle. Many sailors became so accustomed to this way of sleeping that they brought their hammocks ashore with them on leave; the naval use of hammocks continued into the 20th century. During World War II, troopships sometimes employed hammocks for both naval ratings and soldiers in order to increase available space and troop carrying capacity. Many leisure sailors today prefer hammocks over bunks because of better comfort in sleep while on the high seas. Hammocks have been employed on spacecraft in order to utilize available space when not sleeping or resting. During the Apollo program, from Apollo 12 onwards, the Lunar Module was equipped with hammocks for the commander and lunar module pilot to sleep in between moonwalks. In Mexico, hammocks are made in villages surrounding the capital city of the Yucatán, Mérida, are sold throughout the world as well as locally.
They were not part of Classic era Maya civilization. In addition to bark and sisal, hammocks were constructed from various materials, including palm fronds. Quality of native and modern hammocks depends on the quality of the material and the number of threads used. Mayan hammocks are made on a loom and are hand woven by men and children. Hammocks are so symbolically and culturally important for the Yucatecans that the most humble of homes have hammock hooks in the walls. El Salvador is a large exporter of hammocks; the valley in which San Salvador City sits is dubbed "The Valley of the Hammocks" because the Native Americans used hammocks to "repel" constant earthquakes. The colonizing Spaniards used the term as an allusion to earthquakes rocking the valley like a hammock. Hammocks are a big part of Salvadoran culture and are used for afternoon naps, it is socially ac
