Visco elastic polyurethane foam might appear like a complicated term, but is actually very descriptive of a particular kind of bedding material. Adding a few chemical substances to polyurethane foam will enhance the density and viscosity of the foam. The new foam that is created is called visco elastic polyurethane foam. But, it is commonly referred to as memory foam because of its unique traits. To state it another way, memory foam is simply polyurethane foam with a few additional chemical additives that give it the flexibility to adapt to the shape of the individual human form.
There are several great advantages as well as some drawbacks to visco elastic polyurethane foam. Deciding if it is the right mattress for you personally necessitates a discussion of its properties. Memory foam was originally created for NASA in the 1970s, but manufacturing prices were so high it wasn't deemed marketable to the broad public. But, as manufacturing prices decreased it ultimately started being sold successfully in the 1990s. It didn't take long before customers turned it into an extraordinarily popular bedding choice.
Memory foam mattresses, or visco elastic mattresses, are much heavier than standard spring mattresses because of their greater density and firmness. This increased density and firmness helps improve their durability which means they'll last for a lot of years. Also, these mattresses don't have any springs that can dig into your body and thus can supply steady support in all areas.
The hips and shoulders can receive a disproportionate amount of pressure on a standard mattress. But, with a memory foam mattress the weight of an individual will be spread over a bigger region which can cut the amount of pressure on any single spot. Additionally, with reduced pressure comes less tossing and rolling over which can lead to a better night's sleep. Due to those individual traits many folks with back pain find pain relief when slumbering on a visco elastic mattress.
On the negative side visco elastic foam is very heavy, making them hard to reposition if wanted. They can additionally create a strong smell when brand new because of their off gassing. This is brought about from the chemical substances that the mattress is created from, producing a smell comparable to paint. But, the smell will disappear when it's had some time to off gas. Some folks additionally have a problem with them being too hot. Since memory foam retains body warmth they will sometimes become uncomfortably hot to some individuals.
Even though these mattresses are ordinarily more high-priced than standard mattresses it is usually not an issue for the reason that they ordinarily last much longer. If you have bronchial asthma or allergies you'll want to be conscious that a visco elastic mattress can cause reactions in some people. Hypersensitive reactions and skin sensitivities can come about because of the chemical substances within the visco elastic foam. But, this dilemma can ordinarily be solved by shopping for a high quality memory foam mattress cover. The cover will act as a barrier between the sleeper and the bedding material.
As you can see, there are various advantages to purchasing a memory foam mattress along with some drawbacks. By examining these issues you'll be in a position to make an educated choice on whether a visco elastic polyurethane foam mattress is right for you personally.

What happens if multiple commands are set to the
pump by the
same pendant?
Will the bed go flat if the system is unplugged?
No, the bed will continue to hold air if it is not
connected to electricity.
Will the chambers go flat if the hose connections at
the mattress
faceplate are disconnected?
No. The valves are designed to seal the air in the
chambers. However, disconnecting the hoses at
the base of the pump will result in the chambers going flat.
Why is the bed at maximum pressure when I lay on it,
but seems
less full when I stand up?
The measurement of PSI (pounds force pressure per
square inch) is affected by the amount of
weight applied to the bed. If you are sitting or
lying on the bed while it is inflating, the added
pressure caused by your weight will cause the system
to stop sooner than if there were no weight
on the bed. To obtain maximum inflation, the bed
should be filled to .75 PSI before
any weight is put on the bed.
Why didn’t the pump respond when a command was sent?
There could be several reasons. First the desired
pressure may already exist. If so, the pump would
sense that and remain dormant. Second, the pump may
have responded and been
too silent to hear, or the change too slight to be
felt. There are 65 separate settings for each side of
the bed and slight changes in the target PSI are too
subtle to feel.
What is the clicking noise that comes from the
system?
This sound may be heard when the pump is deflating.
It is normal and means the deflation
mechanism is working properly.
What should I do if the pendant display doesn’t
light?
Check the connection of the pendant cable into the
side of the pump; unplug it, wait 15 seconds
and plug it in again. If that doesn’t work then
unplug the unit from the wall, wait
15 seconds and plug it in again. The pendants should light.

Shooting Tips
Digital Readout Issue – If the pressure in the mattress is set while
she’s lying on the bed, then the difference in pressure
between her head, torso and feet is not surprising. Each
zone is reading PSI (pressure per square inch). As your
head is heavier than your feet, the amount of air needed to
create the pressure setting for your head is less than the
amount of air needed to create the same pressure setting for
your feet. Considering the human design centers the
majority of our weight between the shoulders and hip area,
when set to the same PSI as the head/foot area, the torso
section would require the least amount of air to create the
same pressure setting.
Deflating After Increased Pressure – If you’re only changing the pressure by a
couple hundredths of a PSI this does happen. Please
allow me to explain why. If you’re adjusting the
pressure by a few hundredths of a PSI, this is a very small
pressure change. When you move on the mattress at all,
it can easily create a pressure change of a few hundredths of
a PSI or more. Therefore, in some cases, just the
movement to change the PSI setting can increase or decrease
the PSI more than you were trying to change it with the
remote. Our engineers and code writers are currently
working to see if this is something that can be changed
without compromising the sensitivity and accuracy of the pump,
but they have not yet found a solution. We recommend
that PSI changes are made in larger increments of at least .05
(sometimes more) in order to avoid this issue. On my
mattress, I tend to go up .10, then down .07 when I want to
increase pressure by just a bit.
Suddenly Goes Flat –
this is concerning. How often does it go flat? If
it doesn’t go flat often, are there any circumstances that
seem to cause the deflation aside from the loss of
electricity? If it happens often, please have the
customer set the mattress at a comfortable air pressure level
and disconnect the chambers from the pump for at least 24
hours (or as long as it usually takes to go flat if longer).
It is important that they try to sleep on the mattress or do
something so apply pressure to the chambers during this test
(leave books or weights on each section). The chambers
should hold air when disconnected from the pump.
