Memory foam mattresses have become quite common today. A memory foam mattress is different than any other average foam mattresses out there. As a matter of fact, their development began with the US space program, among other things. It is due to research done by NASA that got into the development of the memory foam mattress.
The memory foam was first designed by NASA in order to assist 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 breakthroughs that were made on the memory foam was able to help provide benefits on the medical area instead.
Memory foam is made out of polyurethane combines with extra chemicals in order to add to the foam's viscosity level. This will help increase the foam's density. The chemicals applied on the polyurethane as well let it to get firmer in cooler temperatures and get softer when warm. This way, the foam responds to body heat and lets 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 permits the foam to mold to the shape of the body more quickly.
Memory foam mattresses were particularly expensive for average use. But as many of its advantages have been found above all in the medical field, the said foam has become more widely available in recent years and has become comparatively cheaper to purchase. It has since moved from being used as a mattress for bed bound patients in hospitals to foams found in homes for people who call for a better level of comfort and support while 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 at first than ordinary foam mattresses, they are more long-lasting and may provide better support and additional benefits to users for a longer time period.
One of the primary 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, either deliberately or through necessity.
People who are bed bound for long periods have been witnessed 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, leading to bed sores.
This can be prevented by using a memory foam mattress which can help minify the pressure caused in the same way by molding its shape to the contour of the body.
