The annals of the Polyurethane Foam Mattress may be traced back to NASA's Ames Research Center. NASA's Ames Research Center borrowed a project to style a mattress foam that will help to relieve pain of the astronauts due to g-forces back in the 1970s. NASA assumed the foam product should be used to conform to the body's form. The person might ultimately move out of the positioning, though creating a mold for that body can help solve the issue. As a result, wrong stress points will soon be created about the body. Later, a way to produce a foam that could evolve the your body's form was found by the study team from the Ames Research Center of NASA. It's a visco elastc foam that may evenly distribute the body's weight towards the foam area.

In 1991, Tempur Pedic, a company situated in Sweden sold the people the research mattresss foam in Sweden. After that, Tempur Pedic sold the memory mattress foam to the people that are now living in Canada and Usa. Tempurpedic's bed became popular. Tempur Pedic's achievement had caused the companies provide them for the local buyers and to make their own types of foam beds.
Synthetic polyurethane foam product is employed as the foam memory. The mattress manufacurers will add various kinds substances to change the occurrence of the foam. The foam could have greater density following the chemical is included. Besides, the manufacturer may add a visco elastic foam product. The visco elastic foam is nontoxic. Just how much substances are used within the foam's manufacturing process detemins the foam fat. Many foam mattress has a fat of 4 - 5lb. Lighter memory foam mattress weight in-between 2 - 3 pound.
