Memoryfoam mattress can be a type of bed that is made from memory. Besides polyurethane, it is also produced from other types of substances. The substances which can be added to the bed foams provides it the ability to increase in thickness. Memory foam mattress can also be called viscoelastic memory foam. The mattress was created in order to meet with the mattress shoppers' demand.
The history of the Memory Foam Mattress may be traced back again to the Ames Research Center of NASA. The Ames Research Center of NASA funded a project to style a bed foam that will help to ease backpain of the astronauts caused by gforces within the 1970s. NASA thought that the foam material must be applied to adapt to the form of the human body. Though creating a form for the body can help solve the problem, the individual might ultimately move out of the positioning. About the body, wrong stress points will soon be established as a result. Later, a way to develop a foam that could conform the your body's condition was discovered by the research staff from NASA's Ames Research Center. It is a elastc foam that can consistently distribute the weight of your body to the foam area.http://thebest-mattress.com
Polyurethane foam material is used while the foam memory. The mattress manufacurers may include several kinds of chemicals to change the thickness of the foam. The foam could have greater density following the chemical is included. Besides, a visco elastic foam material will be added by producer. The visco elastic foam is non-toxic. The foam weight is detemined by howmuch compounds are used in the foam's manufacturing process. Lighter memoryfoam bed weight in-between 2 - 3 pound.
The development triggered Fagerdala World Foams of Sweden to test out it and promote it to the people. In 1991, an organization situated in Sweden, Tempurpedic sold the study mattresss foam towards the people. After that, Tempur Pedic sold the memory mattress foam for the people that live in Canada and Usa. Tempur Pedic's bed became popular. Tempur Pedic's achievement had caused the suppliers sell them towards the local people and to generate their particular variations of memory foam mattresses.
