Memory foam was originated quite a long time ago. The original technology was formulated by NASA scientists researching products for the space program.  The product was never actually used for the space program however and the forumula was taken by a Swedish company who sought to use the product in commercial applications.  A great deal of research has gone into finding the best use for the products.  It became obvious relatively quickly however that in the domestic setting bedding products made best use of its particular characteristics.

The foam is actually more accurately called visco-elastic foam.  The visco part is due to the fact that the foam behaves like thick liquid, the elastic part due to its ability to return to its original shape.  The term elastic refers to the behaviour of the foam.  When warm the foam becomes soft and pliable, but when cool returns to the shape it started out as.

The foam will warm up when someone lies upon it. As it warms it will flex and effectively create a mould of the person lying upon it. The mould around the body is enhanced because the foam around the body which is not in contact remains cool and firm. As you can see there are certain uses of memory foam which make more of it's characteristics than others. In particular products such as mattresses, pillows or a memory foam mattress topper would be ideal. Headaches or back ache can arise from sleeping on a surface that causes stress to the body from pressure points. Memory foam avoids such problems. By supporting every part of the body in contact with the foam the body is very evenly supported.

Once used the sleeper will usually awake to find they have had a great nights sleep. They feel rested and rejeuvenated and ready to take on anything. Using a memory foam mattress topper, perhaps together with a memory foam pillow would be a really good idea. It is almost guaranteed to improve your nightly sleeping experience and if you have not decided to do so already you are recommended to try it out.
