You've seen the television ad for memory foam mattresses, touting the wonders of being able to jump on the bed without disturbing (gasp!) a dark-colored beverage. If you are like many people, you may have wondered if there are any other benefits to foam mattresses aside from the ability to have trampoline parties with red wine. In fact, memory foam has a variety of uses, and different types of memory foam can be used for various needs. Of course, the most popular consumer use for memory foam is in home bedding.
Memory foam was originally developed by NASA to help relieve the immense pressure on astronauts during lift-off. The original foam molded to the body in response to body heat and helped distribute the pressure more evenly around the body. The memory foam is made from a special formulation of polyurethane, and in fact was originally too unstable for the consumer market. Over time, a new recipe developed and began to be used in the healthcare industry. The memory foam mattress was originally used in hospital beds to help prevent immobile patients from getting bedsores due to continual pressure on certain areas of the body. The foam was then used for specialty pillows and wheelchair cushions as well.
Foam mattresses didn't hit the consumer market until 1991, when the Tempur-Pedic mattress was released by a Swedish company. A few years later, a line was released in America. Foam mattress reviews praise the product for providing a comfortable and firm bed space, as well as preventing allergies. The mattresses are made of a more dense material, which allows it to support the body while molding to it. Some people who have joint or back troubles state that it helps keep their bodies in alignment throughout the night. The hypo-allergenic claims are due to the fact that the beds are made from a synthetic, not organic, material that makes it less likely to attract allergens. Some memory foam mattress reviews claim that the mattresses do not collect dust mites, but they still may, since dust mites feed on dead skin cells, which are found in any mattress.
