Foam mattress can be a kind of mattress that's produced from polyurethane. Besides polyurethane, it's also made from other forms of chemicals. The chemicals which might be added to the bed foams allows the ability to increase in occurrence to it. Memory foam mattress is also called visco elastic polyurethane foam. The bed was created so that you can meet with the desire of the bed consumers.
The real history of the Memory Foam Mattress can be traced back again to NASA's Ames Research Center. NASA's Ames Research Center financed a task to design a bed foam that can help to alleviate backpain of the astronauts due to g-forces inside the 1970s. NASA considered that the foam material should be used to comply with the shape of your body. The person would eventually transfer of the career, although making a shape for your body can help fix the situation. Consequently, incorrect stress points will soon be created about the body. Later, the study group from NASA's Ames Research Center identified a method to develop a foam that may evolve the your body's design. It is a visco elastc foam that will evenly distribute the weight of the human body for the foam area.www.amerisleep.ca/as2.html
In 1991, an organization situated in Sweden, Tempur Pedic offered the research mattresss foam to the people. Next, Tempurpedic offered the memory mattress foam for the people that reside in Usa and Canada. The mattress of Tempur Pedic became highly popular. Tempur Pedic's success had caused the companies provide them for the local consumers and to create their particular types of foam beds.
Synthetic polyurethane foam material can be used whilst the foam memory. The mattress manufacurers may include several types of chemicals to change the thickness of the foam. The foam could have higher thickness following the substance is included. Besides, a viscoelastic foam material will be added by the maker. The viscoelastic foam is non-toxic. The foam fat is detemined by howmuch chemicals are used inside the production means of the foam. Most memoryfoam mattress has a weight of 4 - 5lb. Brighter memory foam bed fat inbetween 2 - 3 pound.
