Memory foam was created for NASA in the 1970’s. It became available to the public first as a mattress topper and then in the 1990’s the full memory foam mattress was put on the market. Since then the memory foam mattress has become the fastest growing product in the bedding industry. With more companies selling their version of the memory foam mattress consumers have become more and more confused about what they should be looking for when considering a memory foam mattress for themselves.
Memory foam, or visco-elastic polyurethane foam, is made from the same material used in thermal insulation. The other chemicals that are used in the production of memory foam are a closely guarded secret. Chemists have created many combinations of chemicals, resulting in various densities of memory foam. Each kind is slightly different, but they all share the same astonishing properties.
On a regular mattress, metal springs keep your body from falling through. They flex under your body’s weight, holding you up. But memory foam doesn’t respond to weight as much as heat. We all know that our bodies are not flat. There are hollows at the small of the back, the neck and the knees. When we lie down on a traditional mattress, the springs touch the rest of the body, but can’t reach these spots, leaving them unsupported . When we lie on a memory foam mattress, something very different happens.
The foam warms where your body touches it: the head, shoulders, hips and feet. The warm portions of the mattress become softer, letting these parts of the body sink slightly. Amazingly, the other parts of the memory foam mattress don’t change. They can then touch the hollow parts of the body that would otherwise be left unsupported. Because of the uneven heat, the mattress conforms to the exact shape of the body.
Dust mites don’t like memory foam as much as we do. In fact, they find the material very difficult to live on. That is a breath of fresh air for anyone who suffers from indoor allergies or breathing problems that might be worsened by mites. Although products vary from company to company, most memory foam mattresses are also treated with an antimicrobial solution. This prevents germs from living on the mattress as well as on pillows, toppers or pads.
These type of mattresses are also more durable than traditional spring mattresses. Springs that flex every night eventually bend beyond their capability. The result is a mattress that sags in the middle, giving even less support. Memory foam doesn’t wear out because it changes chemically, not mechanically. There are no moving parts to break or bend, only the natural properties of the foam.
With benefits like these, how could I resist? Suddenly, my joint pain is gone. My muscles don’t have to work all night to support my neck and back. The mattress reviews does it for me. I don’t find myself waking up to toss and turn, searching for a more comfortable place. Most importantly, I’m able to live pain-free without turning to medications. I owe it all to my memory foam mattress, its heat-sensitive formulation, and the scientists who brought this technology to the world.
