Of all the great strides in science, who would ever think that the moon walk would affect your bed? Scientists had to come up with a material that would protect the astronauts body from the G forces experienced during ignition and re entry and found a Visco-elastic compound. This compound had a few teething problems and over the years was changed to produce what is now Isotonic memory foam.

In a complicated process of mixing compounds and adding bubbles, foam is produced in various densities. But unlike other types of foam it has open cell foam, so when pressed on the air moves into the adjacent cells and when you lift the pressure the air can return. You may wonder how this has any significance in your life.

If you have a mattress topped with Isotonic memory foam you may already know the answer. This foam behaves in a rather remarkable way. It can conform to your exact body shape using your body weight and temperature. So it gives your body the support it needs while sleeping and avoids placing too much pressure on parts of your body by distributing your weight over the whole surface area. It is breathable; there are two distinct advantages of this. The first is that it prevents you form getting too hot. The other is that it does not encourage the growth of mould. To aid this most foams are treated with anti fungal and anti bacterial retardants.

Because of the nature of the product it is wonderful for people with allergies. It is in itself non allergenic, and does not encourage dust mites to breed. For people with asthma and allergies it can be very beneficial.

When you are sleeping your body needs to relax, but be supported to avoid strain. The memory foam does this. It is not hard and unyielding but not too soft that you have no support. Sleeping with the correct support can assist tired and sore muscles to relax and recover.

Because beds are a costly item one should investigate really carefully before purchasing a new one. But should your old bed be in generally good shape but perhaps not as comfortable as it used to be you can purchase Isotonic memory foam mattress pad that goes on top of your existing bed. These come in different thicknesses, the 3 inch being the most popular. Memory foam is also used in various other applications such as pillows and neck travel pillows; it has found its way into medical practice too. Memory foam is used for people in wheel chairs and for people who are bed ridden. The way in which is distributes body weight helps prevent pressure sores and makes people who are not mobile far more comfortable.
