Foam mattress is just a sort of mattress that is produced from polyurethane. Besides polyurethane, it’s also produced from other forms of chemicals. The compounds which can be included with the bed foams gives it the ability to increase in density. Memory foam mattress is also called viscoelastic polyurethane foam. The mattress was created as a way to meet with with the requirement of the mattress shoppers.

The history of the Foam Mattress may be traced back to the Ames Research Center of NASA. NASA’s Ames Research Center backed a task to style a mattress foam which will help to ease back pain of the astronauts due to g forces in the 1970s. NASA considered that the foam material should be used to conform to the design of your body. Although developing a form for your body can help solve the issue, anyone could ultimately transfer of the positioning. As a result, wrong stress points is going to be established on the body. Later, a method to develop a foam that will evolve the your body’s design was located by the research staff from NASA’s Ames Research Center. It’s a elastc foam that will equally distribute the human body’s weight to the foam area.

The discovery triggered Fagerdala World Foams of Sweden to test out it and sell the consumers it. In 1991, an organization located in Sweden, Tempur Pedic sold the investigation mattresss foam for the people. After that, Tempur Pedic offered the memory mattress foam for the people that are now living in Usa and Canada. Tempurpedic’s bed became very popular. The achievement of Tempurpedic had caused the producers promote them to the local people and to produce their particular variations of polyurethane foam mattresses.

Synthetic polyurethane foam product can be used because the foam memory. The bed manufacurers may add several kinds of chemicals to improve the thickness of the foam. The foam may have higher thickness after the chemical is included. Besides, the manufacturer may put in a viscoelastic foam material. The viscoelastic foam is non-toxic. The foam fat is detemined by just how much substances are employed inside the foam’s manufacturing process. Most memory foam mattress features a weight of 4 - 5lb. Brighter polyurethane foam mattress fat in between 2 - 3 lb.
