Memory foam mattresses have become quite common
nowadays. A memory foam mattress is unlike any other ordinary foam
mattresses out there. In fact, their development began with the US
space program, among other things. It is due to research done by NASA
that went into the development of the memory foam mattress.
The memory foam was first designed by NASA in order to help astronauts
cope up with the high pressure that can be caused by extreme G-force
that occurs when the space shuttle take off for space. Although it has
not been used for the space program, the research and discoveries that
were made on the memory foam was able to help provide benefits on the
medical field instead.
Memory foam is made out of polyurethane combines wit additional
chemicals in order to add to the foam's viscosity level. This will help
increase the foam's density. The chemicals used on the polyurethane
also allow it to become firmer in cooler temperatures and become softer
when warm. This way, the foam reacts to body heat and allows the foam
to mold itself to the shape of the body in a matter of minutes. A
memory foam that is less dense is more pressure sensitive and allows
the foam to mold to the shape of the body more quickly.
Memory foam mattresses were particularly expensive for ordinary use.
But because many of its advantages have been noticed most especially in
the medical field, the said foam has become more widely available in
recent years and has become relatively cheaper to buy. It has since
moved from being used as a mattress for bed bound patients in hospitals
to foams found in homes for people who require a better degree of
comfort and support when lying down.
A memory foam mattress is denser than ordinary foam, making it also
heavier. Its denser properties also make it last longer than ordinary
foams. In the long run, although memory foam mattresses may cost more
to buy initially than ordinary foam mattresses, they are more durable
and may provide better support and other benefits to users for a longer
period of time.
One of the main advantages of memory foam mattresses is that it can
mold itself to the shape of a person that lies on it. This provides
better contours that support the body better than ordinary foams. As
such, it is a better mattress to be used by people who are more prone
to stay in bed for long periods of time, either by choice or through
necessity.
People who are bed bound for long periods of time have been found to
suffer from bed sores and even gangrene. This is due in part to the
pressure that occurs between the foam and the bony regions of the body
when lying down. The pressure can cause blood to stop flowing to a
certain region of the body, resulting in bed sores.
This can be prevented by using a memory foam mattress which can help
lessen the pressure caused in the same way by molding its shape to the
contour of the body.
