Getting Down With A Memory Foam Mattress
If you're wondering what all the fuss is about, with
regard to a memory foam mattress, then you could be in for a happy
experience. Many of those who need very good support while they sleep,
yet who are uncomfortable on really firm mattresses, sing the praises
of memory foam. This substance is actually called visco elastic foam,
and it's the unusual properties of this kind of foam that make the
mattresses so comfortable.
Visco elastic memory foam is comprised of tiny, spherical, weight and
temperature sensitive cells. As the cells heat up, they soften and
spread pressure, which means that as you lie down on a memory foam
mattress, your body heat makes the initially firm substance of the foam
relax and conform to your own shape. Once your heat is removed, the
tiny cells firm up again and return to their original shape. This, as
you might imagine, is where memory foam gets its name.
There's more to the support than that, though. The visco memory foam
only heats up and becomes elastic down to a certain depth. So the top
layers of cells will soften and adapt to your body shape, yet the foam
farther down remains as cool as before, and therefore doesn't change.
So it retains its shape and provides extra underlying firmness, meaning
that memory foam mattresses give you both the contoured support above
and the firm support below.
Another factor in both the support and the shape of the mattress is its
own density. You might find inexpensive memory foam mattresses with a
density of 1.5 pounds per cubic foot, and another of 8 pounds. A higher
density will provide more support and relief for those with hip or back
problems. Additionally, there are single, double, queen or king size
memory foam mattress choices available, as well as memory foam contour
pillows.
What all of this information means, in the end, is that even the
pressure points of the body that push harder into a mattress than other
points do (things like hips, for example) are relieved on a memory foam
mattress. Since the entire body is supported equally, this can help
those with arthritis and even bedsores. A memory foam bed might be just
the thing you're looking for if you want to sleep without getting stiff
and sore.
