Have you been thinking about acquiring a memory foam mattress or a memory foam topper or pad? You must have seen hundreds of compelling adverts this year on memory foam products.
The fact of the matter is that memory foam is a first rate product that has been around for forty years and the simple reason why you have the opportunity to purchase some now, is because the cost has fallen greatly over the last two or three years.
Forty years ago there was just one company producing this revolutionary new foam which was a spin-off of the NASA space programme and production costs were horrific, but nowadays production costs have dropped and many more companies produce memory foam and the competition has lowered the price too.
Memory foam has always been a boon to sufferers of bad backs, arthritis, allergies and sensitive skin, because as it wraps itself about your body it increases the surface area by which your body is supported and increased surface area equals less pressure.
The cell structure of memory foam permits you to adjust its temperature very easily because it sucks in the surrounding air. In regular foam, the bubbles are completely sealed so your body heats up the air trapped within and it stays hot because it can not escape.
However, the bubbles of air in memory foam are not entirely sealed, so as you move about, air is passed from one bubble to another. This means that some air is squeezed outside the mattress and more air is sucked in. Therefore, you can control the temperature of the mattress by regulating the temperature of the air in the room.
The first maker of memory foam mattresses thirty years ago was Tempurpedic and they are still often perceived as the brand leaders because they have the most experience making mattresses from memory foam, but they are also the most expensive.
Other manufacturers are Sealy, which is no new-comer to the world of mattresses, being the largest manufacturer of mattresses in the world. Serta is also in there.
There are two fundamental kinds of memory foam: high density and low density and both of them have different characteristics. High density reacts more to weight and low density reacts more to heat, so if you go shopping for a memory foam mattress, you will have to understand what these terms mean. Some manufacturers have put layers of either type in order to endeavor to gain advantage from every feature.
There is no question that memory foam mattresses have come down in price a great deal recently and they will probably continue to fall in price, but if you want to dip your toe in to find out more, you could get a good memory foam topper or pad to put over your existing mattress. That option costs less than a hundred dollars. Look on eBay or Amazon.
Only one last article of advice on this wonderful new foam, if you decide to get a memory foam topper instead of a memory foam mattress, do not buy anything that is less than two or three inches in thickness..
