Foam mattress is just a form of mattress that's produced from polyurethane. Besides polyurethane, it is also produced from other forms of substances. The chemicals which might be included with the mattress foams presents it the capability to increase in density. Memory foam mattress can be called visco elastic polyurethane foam. The mattress was developed as a way to meet up with the desire of the mattress customers.
The history of the Memory Foam Mattress may be traced back to the Ames Research Center of NASA. NASA's Ames Research Center borrowed a task to style a mattress foam which will help to alleviate back pain of the astronauts due to gforces within the 1970s. NASA considered that the foam material should be used to comply with the body's form. Anyone could eventually transfer of the position, although creating a mold for the body can help to fix the situation. Because of this, improper pressure points is going to be created about the body. Later, a way to create a foam that will conform the the body's design was found by the investigation team from the Ames Research Center of NASA. It's a elastc foam that may consistently distribute the weight of the human body towards the foam surface.Best mattress for back pain
Polyurethane foam material is used while the foam memory. The bed manufacurers may include several kinds of substances to alter the occurrence of the foam. After the chemical is added, the foam will have higher density. Besides, producer can add a viscoelastic foam material. The viscoelastic foam is non toxic. Simply how much compounds are employed inside the production process of the foam detemins the foam weight. Most foam mattress has a weight of 4 - 5lb. Lighter foam bed fat among 2 - 3 lb.
In 1991, a business based in Sweden, Tempurpedic sold the investigation mattresss foam for the people in Sweden. After that, Tempurpedic offered the memory mattress foam towards the people that are now living in Canada and Usa. The mattress of Tempurpedic became very popular. The success of Tempurpedic had caused the manufacturers sell them for the local people and to generate their own designs of foam mattresses.
