Memory Foam Mattress that you can use 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.
