Visco elastic foam" is the technical term for "Memory Foam". Density is what puts the "memory" in memory foam beds. Higher density visco elastic foam provides better performance than low density foam. Be sure to ask about the density of your mattress

Visco-elastic memory foam is being called the biggest breakthrough in the bedding industry since springs were introduced to mattresses back in early 1900's. Memory foam is a better pressure reliever than any other type of material, and that is the reason it is used in so many different medical applications. Memory foam is said to be viscoelastic and is made from polyurethane. The reason it is called this is that it temperature sensitive. The lower the temperature, the more viscous or resistant to change it is. On the other hand at higher temperatures it tends to be more elastic.

What really brought Visco-memory foam to prominence was when NASA decided to release its development on the technology to the public for commercial use. Most companies passed on the development of visco-elastic memory foam due to the challenges that come with new technology. One Swedish company persisted and created the first usable memory foam in1991, the rest is history.

Memory Foam offers a user many benefits. The most obvious is more comfort due to the reduced pressure on the body and spine. In addition, users of visco-memory foam mattresses have been proven to have more deep sleep, toss and turn less, and get higher quality of sleep. In other words, it is possible to feel more rested in less time on a memory foam mattresses than on traditional beds even latex mattresses.. If you have allergies, memory foam can be especially helpful; it is both hypoallergenic and dust mite resistant. Memory foam beds also offer significant benefits for those suffering from poor circulation,
