A Guide To Memory Mattress
By Cindy Heller
Memory foam was formerly developed for NASA in the 1970's and was swiftly noticed by the medical community as a possible aid for people in hospitals, nursing homes and wheelchairs that were susceptible to pressure sores. The benefit to this material was the ability to dispense pressure over a greater area. At the same time as the early memory foam mattress did seem to mitigate areas of the body around the pressure points, these first cushions did not last particularly wear and needed replacement too often to be considered cost effective.
Memory foam is probably best known by the majority of people as the substance that was used by the astronauts to protect them from the extreme g-forces occurring during the take-off of the space shuttle. The memory foam is made from polyurethane and other chemicals that add to its thickness level, thereby increasing its density. It is also referred to as viscoelastic polyurethane foam. Depending on the chemicals used and it's on the whole density, generally it is firmer in cool temperatures and softer when warm. Higher density memory foam reacts to body heat which allows it to form itself to the shape of a warm body in just a few minutes. Lower density foam is pressure sensitive and thus will mold more quickly to the shape of the body. This allows memory mattress to be offered in different firmness levels.
Not all memory mattresses are produced equal, there are some made with the highest quality of materials designed to last, while others will basically not provide sufficient support and durability to make them worth the money. Hence, it is important to do your homework before purchasing a memory mattress in order that you know what to look for in a high quality item that will last you a good long time.
In the beginning after its discovery, memory foam was considered as too expensive for general use, but today it has become less expensive to produce and now is widely available all over the world. It is one of the most common use today is in mattresses, pillows, and memory mattress toppers.
Some memory foam mattress toppers and mattresses, when bought brand new, tends to give off a distinct chemical odor which many people describe as very unpleasant. Over time the strength of the odor decreases, even though yet some people remain sensitive about it. It would be a good idea to discuss this with the salesperson, as it relates to the warranty, before you decided to buy it.
