Have you ever priced a visco memory foam mattress? Compared to other types of mattresses, they are quite expensive; however, if you've ever had a chance to lie down on one of them, the comfort probably blew you away. On the showroom floor, memory foam mattresses shine far and away above any other kind of bedding. Unfortunately, though, some of the benefits don't last with certain brands of mattresses, and you once you've purchased one and started sleeping on it, problems may begin to crop up. Obviously, this is unacceptable with such a pricey mattress, but most warranties on bad ones won't extend to the defects in workmanship, and the consumer is left holding the bag.
So how do you go about identifying a good visco foam mattress? How can you protect yourself from those made of inferior memory foam that isn't going to hold up as advertised? After all, when you spend several thousand dollars for a mattress, you have every right to expect the highest quality. The first thing you need to know is that all visco foam isn't created equally. Every company that uses it comes up with their own recipe, so to speak. Memory foams are graded on 4 points:
1.Weight or density – the amount of chemicals used in the foam's composition. The more chemicals, the more visco-elastic the product will be. Some mattresses use 2-3 pound densities while others go as high as 4-5 pounds.
2.Indentation load deflection – the higher this number is, the firmer the foam
3.Resilience – the foam's springiness based on the rebound of a steel ball dropped from a height of 3 feet. The higher the rebound, the more durable the foam's compression forces.
4.Tensile – measured in pounds per square inch, this is the indicator of how far the foam can be stretched. This usually doesn't effect memory foam mattresses.
When you go to buy a visco foam mattress, start by looking at the warranty that it has. The better the warranty, the more you can be assured that it is a good quality mattress. The best test of a memory foam mattress is if you can try it without a box springs under it. A top-quality mattress shouldn't need a box springs at all to make it feel comfortable. You also need to take a careful look at where the foam was made. Many mattresses are constructed in the U.S., but they're made using inferior foam imported from overseas. Sticking with 100% American foam, which is regulated by the federal government, is the safest bet.
