Are you thinking about buying a memory foam mattress?
Are you confused about all the hype and confusing claims made by
the different advertisements for memory foam?
I've set out to clear the air, , What washing machine? remove the "smoke and mirrors",
and put into one article all the true information , Choosing The Proper Flooring For Your Room you'll need to

and make poor sleep a thing of the past.
The term "memory foam" or "visco-elastic memory foam" was coined
in the early days of NASA's space program. That's why it's also
known as NASA foam.
Sometimes, a memory foam mattress is referred to as a NASA foam
During lift-off, astronauts were being subjected to tremendous
g-forces that the human body just wasn't designed to endure. The
need for a new material, that would make these conditions
tolerable for the astronauts, spawned the research that resulted
in the invention of this brand new kind of foam.
If water, , Poster, Print or Painting. Where Are You Going To Put It? springs, , A Tutorial To Pumps air , Robotic Vacuum Cleaners or any combination of those things had
been an alternative, the expensive research that followed
wouldn't have been needed, and the need for a new material
wouldn't have existed.
Visco-elastic foam has unique qualities. It is able to mold
itself to the shape of any object that puts pressure on it and,
yet, when the object is removed, it will slowly return to it's
original shape. The picture that comes to mind is the hand above
the memory foam mattress that still has the hand print showing
Memory foam is an open celled foam, which means that air , The Advance of Porcelain Tiles is free
to move from one cell to another, so when pressure is applied,
the affected cells collapse and you feel sort of like you're
floating down into the material.
This collapsing of the cells allows the material to "melt away"
from pressure until the entire surface of your body is evenly
supported over the surface of the memory foam.
It virtually eliminates pressure points.

The problem with the NASA foam was that it "off gassed", putting
off a smell that was overpowering in the confined quarters of a
space vehicle. It was eventually scrapped by NASA. To my
knowledge, it was never actually used on any space mission.
At that point, memory foam was just too expensive to be used for
mattresses and the off-gassing wouldn't have been acceptable
A few medical research companies started experimenting with the
material for use in hospitals. Many patients develop bedsores

Because it was cost effective for this application, these
experiments led to using memory foam in a variety of health
industry settings to alleviate pressure points in hospital

The Memory Foam Mattress Industry Was Born
The memory foam mattress industry started slowly in the early
1990's and then shot into the mainstream in the late 1990's and
So much so, that it's difficult to find a magazine, newspaper,
or television that doesn't have several ads for memory foam
product , Solar Energy Systems for Pools s running continuously.
With that kind of demand for the product , Roman Shades: Light-Wise Window Solution it's no wonder that a
lot of people started forming companies to manufacture and sell
to an audience with this enormous appetite. And, yes, as in all
industries, some companies are born just to make inferior
product , A Checklist for Bathroom Remodeling Plans s and, then, using terminology that is confusing or
misleading, capitalize on the lack of good information , A Place For Everything And Everything In Its Place that's
available to consumers.
So let's clear some of the confusion with a few simple facts.
What Is The Difference Between Good And Bad Memory Foam?
Memory foam is graded by it's density. Imagine yourself , What to Look for in a Telescoping Flagpole cutting
a huge "dice" (yeah, like the kind you throw on the crap table)
out of memory foam 12"x12"x12" and slapping it onto the scale in
your doctor's office.
The weight of that 12" sized cube is how you determine density.
For example, if your "dice" weighed 5.9 lbs. it's considered to
have a density of 5.9, or if it weighs 3.2 lbs. the density is
rated as 3.2.
Pretty simple, really, isn't it. Like most things, we all
thought density would be determined by some E=IR formula or
something terribly complex. You, now, know more about density
than most of the sales people in your local , What washing machine? mattress store.
It's also a fact that the less dense foams are made mostly of
air , The Advance of Porcelain Tiles , not foam. Less foam, less cost to manufacture...they can
sell it cheaper.
For most memory foam mattresses, it's a fact that the human body
is best supported by a density of 5.3 lbs. to 5.9 lbs. Any
heavier than this and it tends to be too dense and won't allow
the proper cell collapsing that allows your body to settle into
it. Any lighter and you don't get the needed support in the hip
and shoulder areas.
Another problem is that the lighter foams won't continue to
return to their original shape after a relatively short
lifespan. They'll lose their comfort.
Some of the 5.3+ lb. mattresses are still going strong after 15
years being just as comfortable to their users as the first
day...and with no body impressions.
Remember, too, that we discussed temperature , Laminate Flooring - Everything You Need To Know. sensitivity. Not
all foam being advertised as "memory foam" is temperature
, Wood Or Metal Playground Equipment sensitive.
Make sure it has this feature , We Have a Damp Problem, No it is Just a Condensation Problem so you get that "fine tuned"
A better memory foam mattress will contain 3 1/2", or more, of
memory foam as a top layer. Any less than this probably won't
keep you from bottoming out and laying on the underlying base
layers of foam. Those foams aren't meant to be in contact with
your body and won't comfortable for you. They are there to help
the memory foam do it's job correctly.
Just remember density and temperature , Kitchen Magic sensitivity, when you go
shopping for your memory foam mattress and you'll be miles ahead
when you purchase.
