Choosing a Memory Mattress

Generally a memory mattress is one of the mattresses also called memory foam. Memory foam is polyurethane with additional chemicals that was discovered by the NASA laboratories in 1966. When this memory foam was released to the public in the 1980s several companies decided to try to make it into a mattress with the result being a memory foam mattress. This memory mattress is one of the higher dollar mattresses you can purchase. Many people swear by it in that it is so comfortable they always get an excellent night’s sleep.

The way a high density foam mattress or memory foam mattress works is that the open cell structure allows it to increase in density and viscosity so that it becomes softer in reaction to natural body heat. It is a long life mattress often lasting from ten to twenty years with a corresponding higher cost than a traditional coiled or innerspring mattress. This memory mattress can mold to the body form within minutes. Then when the body is removed and there is no heat going into the foam the memory foam returns back to its original shape and form. The thicker the foam piece the softer the resulting mattress is and the more the body sinks into it.

There is also a foam mattress made from low density foam and the big difference is that a low density foam does not react to the body heat but to the body pressure and it actually decompresses under pressure. So when you are shopping for a memory mattress make certain what you are getting either low density foam or high density foam. Generally a high density foam mattress will cost more. The more expensive memory foam mattresses will also generally be thicker than four inches. This type of mattress is often used in hospitals for bed ridden patients and it also is an excellent mattress to sleep on because it dose relieve the pressure points when you sleep. This means that different parts of the body will not rest against a hard place that doesn’t move with the bones and muscles and a memory foam will let those bones and muscles be molded by the foam for a good night’s sleep.

When you are looking for a mattress you should make sure your old one needs replacement. Mattresses are expensive and really should be considered an investment. Remember you will be spending at least eight hours a night or approximately three thousand hours a year sleeping on it so you want to get the most comfortable mattress you can afford. And if you sleep more than eight hours a night on it that hour count goes up and that is a good portion f your daily life when you think about it. Also make sure you have the space for the size mattress you want. Since they come in sizes you can choose the size you need. And if the bed has a headboard make sure you have room for that also.
