What is Memory Foam?

Memory foam was developed by NASA in the late 1960s. Astronauts at the time were complaining of discomfort during lift-off, which, as you can imagine, is an incredibly forceful process considering the spacecraft needs to be hurtled beyond the Earth’s atmosphere. NASA began researching ways to improve the aircraft cushion and thus astronaut safety. The answer turned out to be memory foam.

Memory foam has a specialized open-cell solid structure and is created by feeding gas into a polymer matrix. It is supportive, matching pressure applied against it, and can slowly spring back to its original shape. In addition to being used by NASA, it has also been used in sports equipment, medical settings, shoes, and of course, mattresses.

Mattresses that are made from memory foam are denser than traditional foam mattresses. The memory foam that is used in mattresses usually ranges from 1.5 lb to 8 lb density. This makes them quite heavy, but they are also incredibly supportive. Memory foam is known to help relieve pressure points and even prevent bedsores. The third generation of memory foam was released in 2006 and includes gels that prevent body heat from being trapped. This allows users of the best memory foam mattresses to sleep cool by preventing overheating during the night.

Benefits of Memory Foam Mattresses

Relieve pressure points

Memory foam contours to your body and provides even body weight distribution. The result is that pressure points are relieved of stress, so you can rest comfortably. Hospitals and nursing homes have even been known to use the best memory foam mattresses to reduce the rate of bedsores in patient populations!

Reduce dust mites

Because memory foam is incredibly dense, it reduces the risk for dust mite infestation. Compare that to normal, innerspring mattresses, which have been found to host up to 10 million dust mites. The lack of large open spaces and fluffy construction mean that memory foam is an unfriendly environment for dust mites. The best memory foam mattress will also come with a mattress cover to offer even more protection against dust mites and other household allergens.

Prevent motion disruption

Whether you’re sleeping with a partner or with pets, a memory foam mattress will relieve you of the common problem of motion disturbance. The memory foam absorbs motion, whether it’s from someone getting into or out of bed or simply rolling over, so you won’t be awoken by their movements.

Support different sleep positions

Certain mattresses are known to be better for back sleepers, side sleepers, or stomach sleepers. The best memory foam mattresses do a good job of accommodating every sleep position since it molds to your body.

Work with Adjustable Beds

Because memory foam is so flexible and is designed with contouring in mind, it is a good choice for adjustable bases. If you want to raise the head or foot of the bed, a memory foam mattress can easily make these adjustments possible thanks to their compatibility with adjustable bed frames.
