Definition of the mattress: A short biographical review

This semantic evolution comes from the fact that cushions and carpets were thrown to the floor where one wanted to sit or rest. Westerners brought this term back to Europe at the time of the Crusades. The tempurpedic mattress reviews show that a mattress is usually composed of two parts. The lining that covers the suspension and whose function is to give the comfort to the sleeper. The suspension is there for the anatomical support of the sleeper. It allows the spine to stay straight so that the back muscles relax.  Ideally a mattress should consist of a main element that ensures the body’s consistent support.

Memory foam: Tempurpedic mattress

Memory foam had just been invented. These properties were also to reduce muscle tension and to adapt to body movements including weightlessness. In 1991, Tempurpedic, a Swedish mattress manufacturer, introduced this foam into these mattresses. It’s a huge success. And in 1992, this product is marketed in North America. Probably the best using mattress often suggested by the experts to treat your shoulder pain and comfortable side sleeping. With memory foam tempurpedic mattress your comfort is guaranteed.

Tempurpedic Foam Mattresses

There are different varieties of foam whose distinctive element is density. A density range can be identified for the foam mattresses that correspond to the needed support. For a supple support, a density of 20 kg / m³ to 25 kg / m³ is enough. With a balanced or semi-firm support, a higher density is needed, between 25 kg / m³ and 35 kg / m³. If you want firm support, the necessary density starts from 35 kg / m³ up to 50 kg / m³. And if at last you can only support a very firm support it will be necessary to direct you towards mattresses which have a density of at least 50 kg / m.

Polyether and polyurethane foams

These mattresses are made with synthetic foam. There are three main families. The first family is polyether foam. It is low density and offers flexible support. The second family of foam is that of polyurethane. Mattresses made with this foam have a density greater than 25 kg / m³.

The viscoelastic foam

Viscoelastic foam technology was developed by NASA in the 1970s. It was originally designed to protect astronauts from Force G during take-offs and atmospheric entry. The idea was to design a material able to keep its structure while marrying the shapes of astronauts.
