Memory foam beds have become quite common in recent years. A memory foam mattress is unlike any other ordinary inner spring 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 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 to the medical field instead.
Memory foam is made out of polyurethane combined with additional chemicals in order to add to the foam’s viscosity level. This helps 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 mattress that is less dense is more pressure sensitive and allows the foam to mold to the shape of the body more quickly.
When they first came on the market memory foam beds were particularly expensive for household use. However, many of its advantages have been noticed and it has become particularly useful in the medical field, and in hospital settings. With the increase in demand the supply has increased and allowed the price to go down somwhat. It is no longer just found in hospital rooms of bed bound patients, but in the homes of those who are looking for a better, more comfortable night’s sleep.
A memory foam mattress is denser than ordinary foam. Being denser also makes it last longer than the ordinary inner spring mattress. The initial outlay may be expensive, but in the long run, they are more durable and may provide better support and other benefits over a longer period of time, making them a wise purchase.
One of the main advantages of memory foam beds is that it can mold itself to the shape of the person that lies on it. This provides unique and even support to all parts of the body, unlike an inner spring mattress. Because of this, it is a better mattress for people who are more prone lengthy stays in bed.
People who are bedbound frequently suffer from bed sores and even gangrene. This is due in part to the pressure that occurs between the mattress 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.
