Having the unparalleled ability to relieve muscle and joint pain by lowering the pressure and providing support, the visco elastic foam mattress was developed to radically raise the level of the body's support during sleep. Furniture manufacturers, retailers and designers are now making it ever popular to use memory foam in everything from pillows to memory foam beds and mattress toppers. One example is the Tempur-Pedic company, who marketed their memory foam beds and accessories as orthopedic products that would be guaranteed to bring relief to those suffering from troubled sleep cycles. Their products promised to correctly align the spine and improve health overall with better posture, and as a result, visco elastic memory foam mattress toppers, covers, and beds have sold in the millions worldwide.

During the 1970's, a space program first produced the visco foam material in order to relieve pressure points caused by immense G-forces that were exerted on the astronauts during the lift off sequence. Hospitals were the next industry to use memory foam in order to give patients comfortable and healthier visits, which led to memory foam mattress toppers, beds and other furniture items being sold to the rest of the public - and can now be found in homes around the world.

So how does memory foam work? Air passes through one open cell to the adjacent cell as pressure is applied to the visco elastic foam by either your head or body, and it will mold to your shape completely, even though the feeling might be firm at first. Memory foam relieves the pressure points experienced by even the hardest points from the shoulders and hips, as the foam can adjust and conform to the natural height, weight, and body type of its user.

Without the correct support, most sleep positions have the potential to end up being painful or putting pressure on points that can vary greatly depending on the sleeper. However, people have been known to achieve a healthier nights sleep while using a visco elastic foam mattress. Additionally, having being made out of a material resistant to housing dust mites, visco elastic memory foam is a huge advancement from the standard box spring and coil type mattresses. Often, dust mites thrive in environments with high levels of humidity and dead skin cells, but the high density and structure of the visco foam resists providing for dust mites.

Memory foam mattress toppers, pads and covers have often been found to generate excessive amounts of heat by their users, because this is a material that is heat sensitive and uses its open cells to trap heat. While it may not seem like a problem initially, Surface Modified Technology has patented a series of grooves cut into the surface of the foam to reduce the amount of heat from being built up; thus, solving the over warming problem that plagued certain owners of earliest visco elastic foam mattresses.

It's recommended to take caution when shopping for memory foam products, because imitation manufacturers have been known to mix formaldehyde and various other fibers into their foam and attempt to pass it off as genuine visco elastic foam material. When shopping, it is also vital to check for different levels of density in the mattress, as visco memory foam has once been created by pouring liquid foam into molds - which in turn causes greater densities of the product to settle onto the bottom, and lighter densities to rise towards the top. This kind of inconsistency forms a weaker foam and fairly inconsistent layer of density throughout the product. Thankfully, with all the new advancements made in technology, visco foam can now be manufactured through vacuum injection or inside a vacuum chamber to produce a uniformly dense product. As a result, you can literally rest assured that you will be purchasing the most premium of grades of memory foam on the market. I hope these tips and information will help you find the perfect visco elastic foam mattress for you and your home!
