Foam mattress can be a type of bed that is created from polyurethane. Besides memory, it is also made from other styles of compounds. The compounds which are put into the mattress foams gives it the ability to increase in occurrence. Memory foam mattress is also called visco elastic polyurethane foam. The bed was developed to be able to meet the bed shoppers' requirement.The annals of the Polyurethane Foam Mattress might be traced back to the Ames Research Center of NASA. NASA's Ames Research Center financed a project to style a bed foam which will help to ease back pain of the astronauts caused by g forces within the 1970s. NASA assumed that the foam product ought to be applied to adapt to the design of the body. Anyone would ultimately move-out of the positioning though making a mold for that body will help solve the problem. Consequently, incorrect pressure points is going to be formed around the body. Later, the research staff from NASA's Ames Research Center identified a method to produce a foam that can evolve the the body's shape. It's a visco elastc foam that can consistently distribute your body's weight for the foam area.Best mattress for back painPolyurethane foam product is used since the foam memory. The bed manufacurers may add various kinds compounds to change the density of the foam. The foam will have higher density after the compound is included. Besides, the manufacturer will put in a visco elastic foam material. The viscoelastic foam is non-toxic. The foam fat is detemined by how much compounds are employed inside the foam's production process. Lighter polyurethane foam mattress weight in between 2 - 3 pound.The finding induced Fagerdala World Foams of Sweden promote it towards the customers and to test out it. In 1991, Tempurpedic, a business situated in Sweden bought the people the research mattresss foam in Sweden. After that, Tempur Pedic offered the memory mattress foam towards the people that reside in Canada and United States. The bed of Tempurpedic became very popular. Tempur Pedic's achievement had caused the suppliers offer them for the local customers and to create their own designs of foam beds.
