This organization needed something to help astronauts feel comfortable when they launch into space.

The resilient structure of this mattress gives it durability. Back pains and pressure sores are commonplace to astronauts. Consumers can attest to the fact.

But once body heat comes into contact with it, it starts to soften up to follow the contours of the body. The G forces tend to push them back to their seats, thereby developing pressure sores in the process. Memory foam mattresses are purportedly durable.

It is expected to last for more than a decade. A decent brand of memory bed can last for as long as 15 years even with relatively little maintenance. Compared to traditional spring beds, it provides better support to the crucial areas of the body such as the spine, the neck and the lumbar region. This can be attributed to the resilient properties of visco elastic foam. Visco elastic foam technology is originally an idea of NASA.

It is little wonder why adults prefer this kind of mattress. However, this is not true for all brands of memory foams.

The foam is stiff and firm at first.
