Lately, Visco elastic foam (commonly mentioned as memory foam) has become the newest sleeping technology that might help you sleep better. According to Wikipedia, Memory Foam is made from polyurethane and other chemicals that increase viscosity level, which results in increased density and bedding of this type is gaining a solid reputation and increased popularity. One reason is the declining manufacturing costs, the other and more relevant reason is that more and more chiropractors and doctors highly recommended visco elastic foam beds as a way to reduce back pain.
Visco foam mattresses could be the best answer if you suffer from poor sleep or constant aching joints. One reason for their popularity is the visco memory mattress was developed from a material for NASA which helped cushion astronauts against g-forces. Memory bedding reacts to weight and body heat to give superior support while you sleep. You'll notice the foam slowly adjusting to the contour of your body shape while you lie on it. The important benefit is reduced tension on joints usually experienced while sleeping on standard mattresses.
When sleeping on a visco elastic foam mattress, tossing and turning is virtually reduced. This is due to the contoured support that is provided. This is a huge plus and another important benefit is that your sleeping partner will also notice a difference This is due to the quality of this foam which does not transfer motion; they will not feel movement if you get up during the night.
A memory foam mattress will return to its original state due to the foam structure that they're made from. Foam visco elastic mattresses will never sag like a common spring mattress. You benefit from never needing to turn the mattress as you do with common inner spring bedding. One other important side benefit is that bed and dust mites don't like foam, and seldom, if ever make their home where you sleep.
One reason memory foam bedding is popular is that it lasts longer than spring bedding. It's a fact: the average conventional spring mattress has a life span of about five years. After that period, the mattress begins to sag at the center or create divots where you sleep (think how your body lies in a hammock), and this is the main contributor to back pain. Even when inner spring mattresses are brand new, they just don't compete with a foam mattress for a healthy night's rest. Many doctors recommend visco foam mattresses for their patients as relief from insomnia and back pain.
In fact, visco elastic foam foam mattresses can easily last twice as long as an inner spring mattress'. Most often, you're new memory foam mattress includes a 20 year warranty. The reason seller's have so much confidence in their products is due to the foam being manufactured to highly exacting standards. Memory foam bedding will not compress or degrade like conventional bedding does.
