What is memory foam?
Visco-elastic memory foam was
originally developed by NASA and used on space shuttles to relieve pressure on
astronauts caused by G-Forces during take off. It is several times denser than
regular polyurethane foams, is temperature sensitive and always recovers to
original shape. It is also called slow-recovery foam (see picture). Due to its
distinctive property in relieving pressure, memory foam has been developed into
many products such as pillows, toppers, wedges, supports, etc., to benefit
millions of consumers worldwide.
What benefits does
memory foam offer?
Memory foam offers the
following benefits that, in combination, provides the ultimate stress and
pressure relieving support:
Memory foam has higher density and
thus is more supportive and conforms to your body more.
Memory foam is temperature
sensitive. In normal temperature, it is firm, but when you use it, it reacts
to your body temperature and molds to your shape. This way, it minimizes the
pressure points, distributes the weight more evenly and provides customized
High quality memory foam often has
open cell structure that breathes better and helps distributes the weight
all memory foams the same?
No. There are huge differences in quality.
One of the key differences is density. Usually, the denser the foam, the more
supportive it is and the more it conforms to your body. High density foam (e.g.,
6lb/ft3 ) is usually made with molding process while low density (e.g.,
3.5lb/ft3) foaming-and-cutting process.
Durability is another important quality aspect. Due to manufacturing
differences, some foams lose its "slow recovery" property over a short period of
time while high quality foams never lose their resiliency.
Cell structure is also important. High density, high quality foams usually has
much smaller cells and thus many more cells in per unit volume. This helps the
foam breathe better and thus distributes weight more evenly.
How do I know which memory foam product is high quality?
- Hold It: High density memory foam product is heavier than other products of the
Press It: If you use your hand to pressure the foam, it should
recover to its original shape slowly. If the foam recovers too quickly, then the
quality is probably lower.
Look at It: High quality foam usually have smaller and denser cell structure. If
you see big cells, then the foam’s quality is probably lower.
Use It: If the foam loses it’s supportive property and feels like a regular foam
after being used for a short period of time, then its quality is low. High
quality foam maintains its resiliency even after a long period of time.
