What is a memory foam mattress?
Memory Foam is a polyurethane material. In order to increase its density, chemical are added which increases its viscosity level. The combination of the chemicals used determines the visco-elastic nature of the polyurethane foam and depending of such a combination, the foam has the characteristic of being firmer in cooler temperature and softer in warmer environments. Higher memory density foam reacts to body heat. That reacts to a few minutes from the product forms around the shape of the body. The ownership of the polyurethane foam can be demonstrated by squeezing the hand of one in the foam and then scrapped. The foam retains a clear impression of the hand.
In the 1970s, NASA developed memory foam for use in its space program. With the hope that the ability of even pressure distribution of this foam, the phenomenon of extreme G-force be addressed. Ironically, the material was never used in any space program. In the 1990s, the product went on the commercial market in pill form Topper and then as foam mattresses.
A medical company, Tempur, first realized the potential commercial application of the foam. Was investigated different versions of the foam and came out with a product called "Tempur". This Tempur was durable and had the property of pressure reduction.
When memory foam for the first time on the market, was known as T-foam. Chemical gases are released so it is healthy to be used in a closed environment. Over the years, this odor was reduced but could not be spared. The initial T promised a great product foam as Topper bed or wheelchair cushion material. However, noted that he had problems with use over a relatively short time. This early version of the foam was not found to be durable and often break and remain tablets after a while.
Memory Foam has excellent characteristics shown in response to temperature changes and its ability to reduce pressure to distribute weight evenly over a larger area. Therefore, the foam is also found application in medical treatment of patients by preventing so-called "bed sores" that a patient may develop when bedridden. In other medical applications, the foam is used in the chair cushion wheel cushions, pillows or padding for persons suffering long-term pain of postural problems. To retain the heat of the properties of the foam, makes the pain more bearable for a patient suffering from back injuries.
Memory foam is usually more dense, so it is heavier than other foams. Because it is heavier, the foam is still more favorable and comfortable. A new memory foam mattress has a chemical odor that is unpleasant for some people. Although the air takes most of the smell away, some people remain sensitive to smells.
Currently Memory Foam is used in many commercial products such as comfortable mattresses, mattresses and pillows, positional sleep aids, office furniture, the car seat upholstery, footwear, baby cots, car seats, wheel chair cushions, computer carrying cases, tennis racket handles and more.
