An Introduction To Memory Foam
Author: Ricky Lim
 
The first memory foam material was invented in the 1970's by
NASA. At that time, NASA was trying to come up with a material
that could cushion the astronauts when taking off due to the
high G levels. The material was invented yet never made it to
any space program. Instead, several medical companies saw the
potential of memory foam material and adapted it to be used in
the medical industry to help relive bed sores.

When memory foam was first used, though it was effective, it
was also very brittle and was not suitable for long term use.
However, Tempur-Pedic, the swedish tempurpedic manufacturer was
the first company to came up with a new version of memory foam
material that was not only effective in the medical industry
but also had a longer life span. Tempur-Pedic was also
responsible for introducing tempurpedic mattresses and other
related tempurpedic products to the average consumer.

Needless to say, it was a hit with the consumer market as there
was nothing like it on the market prior to Tempur-Pedic's entry.
The ability to conform to your body and body temperature and
pressure relieving properties soon made tempurpedic products
the market leader in memory foam industry.

Lately on, other memory foam companies join in the fray and
came up with many other varieties of memory foam products.
However, they could not duplicate the success of tempur-pedic
products.

Part of the reason for this is most other memory foam has a
lower density per foot than tempurpedic. Typically, tempurpedic
products has 5.3 lb/cubic density while other memory foam
products are in the range of 2.5 to 4 lb/cubic density.

The higher the density of memory foam material, the more
cushioning effect it has. The higher density is also one of the
reasons why tempurpedic products cost more than other memory
foam products.

Another property of tempurpedic products is its visco-elastic
ability. The visco-elastic material will soften and conform to
your body contours and temperature. The lower the temperature,
the more rigid the memory foam material.

Tempur-Pedic has also perfected the memory foam technique,
something other companies have not done. The memory foam
manufacturing process is inherently complicated and not easily
duplicated. This has enable them to produce better quality
memory foam mattress and other products.

Though many companies have tried to imitate the visco-elastic
and density of tempurpedic memory foam, none have come close to
it and this is the reason why tempurpedic products continue to
be well liked by consumers even though the cost is higher than
other memory foam products. Consumers have come to associate
better quality with tempurpedic products.
