In this article, we will discuss everything you need to know about memory foam mattresses.
The Memory Foam mattress is chemically treated with the aim of completely losing its resistance.
The result is a material that, after being compacted, “returns to its original form” very slowly, so it seems to memorize body’s the shape. All this, caused by the compression process.
This absolute lack of resistance provides the feeling of pressure relief that is perceived as comfortable by many consumers at first sight.
The lack of resistance also means that your body is sinking into the material without backpressure, which is similar to lying in the sand.
That is, you suddenly realize that leaving this mould comfortable that your body formed is challenging.

Utilities of memory foam mattresses
To change position in this foam compared to highly resistant materials, much more effort is required than with a latex mattress.
This may not be a big problem for young and agile people.
Nevertheless, for those who suffer back problems or for older people who are no longer so flexible.
This restriction with respect to mobility can be heavy.
It is proven that the effort that someone makes to return to the other side of the body can cause enormous torsional pressure along the spine. This obviously isn’t good for people with back problems.
The second point is that most Memory Foams are very closed-cell foams. Their cells close and don’t allow air to pass through the foam.
This low air permeability results in low ventilation, which is responsible for drying the moisture that always occurs when someone is lying on a mattress.
This excess moisture can cause hygiene problems, in addition to nourishing the habitat of mites.
Fortunately, some mattress products today provide washable mattress covers with antibacterial treatments that prevent problems of a hygienic nature.
It is a viscoelastic foam; it is a polyurethane foam, like a rubber foam.
This, with the difference that some chemicals are used to fully adapt to achieve the “memory” properties of use.
This foam behaves in different ways depending on the temperature at which it is located. That is when it is cold is more rigid and when it is hot, it becomes more uniform.
It adapts adequately to the deviation pressure of the body shape very well.
Therefore, it is used for various medical applications and for rest.
NASA originally developed the viscoelastic material or memory foam with innovative properties.
It was designed to relieve the pressure tissues can cause to the astronauts’ body during the launch of the spacecraft.
That is to say, memory foam arose as a direct result of the space program in the 60s. It was even in the early 90s when researchers were incorporated into domestic use.
For the manufacture of viscoelastic foam mattresses, the adaptation consisted in making the inlet and outlet air faster.
This makes the main disadvantages of this process is that the density of the material is not homogeneous over its entire surface. Therefore, it can cause premature deformation of the mattress.
However, with the moulded and open viscoelastic, the smaller pores ensure that the certified density is constant throughout the surface of the mattress.
In summary, we can make sure that foam mattresses are one of the most suitable for sleeping in good conditions.
Specially designed for those suffering from pain, pressure and blood circulation disorders.
As immediate benefits, it can reduce the pressure of the product in the body, up to 40%.
