The Memory Foam Review is a consumers guide to memory foam mattresses or mattress toppers. Features include the benefits of memory foam, understanding what to look for when buying online, new or used, and reviews of the leading brands of memory foam products on the market.

What is Memory Foam? It is a heat sensitive, visco-elastic polyurethane foam. At room temperature memory foam is harder than at skin temperature, which causes it to soften on contact and mould itself to the shape of a warm body within a few minutes. The foam also holds its shape temporarily – a hand pressed into memory foam will leave a clear impression when removed.

Memory foam was originally developed by NASA in the 1960′s to ease the pressure of extreme G-force during space shuttle take off. It was subsequently used in medical applications, for example with patients suffering from pressure sores or bed-bound for a long period.

Tempur-pedic was the first company to use memory foam in mattresses. Memory foam was initially too expensive for general use, but in recent years it has become cheaper to produce and is now widely available. Many companies have gone to copying the material and using the generic name for it.

Memory foam is one of the most healthy sleep surfaces ever created. Visco-elastic memory foam eliminates uncomfortable pressure points and adjusts itself based on your own body temperature and weight. A high quality memory foam mattress has the ability to improve one’s quality of sleep, alleviate back pain, improve circulation and may even help with some types of sleeping disorders like sleep apnea.
