Most of the memory foam mattress reviews that I read were regarding mattresses that were constructed of a three layer principle with a dense foam on the bottom an intermediate poly-layer and the final layer consisting of approximately 3 inches of five pound density visco-elastic foam. These 5 pound density is important and is really the minimum standard you should look for when buying a mattress as it provides good support and is very comfortable.
Memory foam mattresses have become very popular since their introduction in 1991. Based on pressure absorption technology developed by NASA they are excellent for providing a more comfortable night s sleep. The visco-elastic foam compresses under pressure providing complete support for the body. In the top brands the visco-elastic foam responds to body heat and becomes more pliable providing even better support. These special toppers offer a more affordable alternative to expensive full matresses. The top 3 memory foam mattress topper manufacturers are Tempur-Pedic Serta and Select Foam.
