What are the benefits of visco elastic memory foam pads?
Visco elastic material allows mattress toppers to conform to
your individual curves to relieve pressure points. Rather than
sleeping on your side and feeling pressure on your shoulders, hips and
knees, imagine laying on a perfect mold that supports all parts of your
body. The pressure would be evenly distributed across your side
rather than just on your shoulders, hips and knees.
What is the best foam density for me?
There is not one prefect visco elastic memory foam pad density
for everyone. Instead you should take into account your body size
and sleeping preferences. Lighter customers may find that a 4lb
visco elastic memory foam topper is just right. However if you
are lighter and prefer a firmer feel than a 5lb visco elastic memory
foam pad may be best. Heavier customers should choose denser
toppers. Rarely do our customers find any visco memory foam pad
to be too dense. Denser visco-elastic memory foam toppers make
for better sleep.
How thick should the mattress topper be?
You should choose a thickness based on your size, sleeping position
and desired density. The denser the visco elastic memory foam
topper the thinner the pad can be. Another guideline takes your
sleeping position into account. If you sleep on your side or back
you should choose a 3" pad. If you tend to sleep on your
stomach then we recommend choosing one of our 2" visco memory foam
pads.
Is there TDI (methylenediphenyl
diisocyanate) in my Sleep Aid mattress?
No. When you receive your Sleep Aid topper or mattress, there
are no dangerous chemical residues at all, though TDI is used in the
Sleep Aid production process. The rumor of a “risk” associated with TDI
was invented as a marketing strategy to scare you into buying one kind
of foam over another. While TDI is used in the production of virtually
all kinds of polyurethane foam, no memory foam has any TDI residue after
production is finished. That’s because TDI is consumed during the
production process, and therefore does not remain in the finished
product. Companies who claim to make a safer product by using TDI
alternatives are using scare tactics to sell their foam.

What makes a foam visco elastic?
Visco Elastic foam has higher resistance to change than traditional
foam. This means that as you apply pressure it feels firmer.
The foam will slowly compress under your body weight with the aid of
your body heat. Once compressed a good visco elastic memory foam
pad will hold its compressed shape temporarily before slowly returning
to normal. The slower the change back to normal the better the
quality of the visco memory foam topper.
Do visco elastic memory foam toppers make your body too hot
at night?
Low quality visco elastic memory foam pads do not breath properly
and can be too hot for some customers to sleep comfortably. However,
high quality, dense visco foams allow manufacturers to cut air channels
into the toppers, without compromising support and durability.
Even customers who have mentioned that they often are too hot during
the night find that air channels offer enough air circulation to keep
them cool. Visco elastic memory foam toppers with air channels
offer customers superior support and temperature comfort.
Is there really a difference in visco foam quality?
Yes! Not all visco memory foam pads are created equal.
Low cost suppliers use harmful chemicals such as formaldehyde to produce
their foams. Who wants to sleep on that night after night?
Also visco elastic memory foam pads vary in how slowly they spring
back to normal and how sensitive they are to your body temperature.
Also, many visco memory foam toppers suffer from inconsistencies in
density due to outdated manufacturing processes. The only way
to control foam density is to create it in vacuum sealed chambers which
only Sleep Aid's™
does.
Was visco-elastic memory foam
really invented by NASA?
This is true, however NASA never actually used the product.
It proved to not meet their needs but luckily for sleepers , visco
memory foam was not forgotten. Medical companies realized that
visco-elastic memory foam works wonders to relieve pressure points.
Now visco memory products have made it into wheelchairs, hospital
beds and millions of bedrooms around the world.
What is ILD?
ILD or Indent Load Deflection, is a measurement of how "springy"
a given sample of foam is. Some companies use this measurement as
a way of confusing customers by saying that their memory foam has
a higher ILD than their competitors.
The problem with this, is that ILD is a useless measurement when
applied to memory foam. Memory foam, by definition, is supposed to
conform to the body, so "springyness" is really beside the
point. In fact, you can have two types of memory foam with identical
density, and quality and performance, but vastly different ILD ratings.
In the foam industry, ILD is used to measure conventional foam, but
not visco-elastic or "memory foam". If a salesman tries
to sell you on a "high ILD memory foam" don't let him get
away with it. He's trying to confuse you. Density is a much more useful
and relevant measurement, so stick with that.
