Memory Foam Mattress Topper For Queen Size Beds

This foam is named visco elastic foam, NASA foam plus some other names but it's all derived from the original Best Memory Foam Mattress which was developed for the NASA manned space flight program.

As far as my research goes, I really don't believe any of this foam truly made it's way into a space craft. It turned out to not be suited for space flight.

A Swedish foam business started experimenting with all the foam and finally came up using a variant of it that was suitable for mattresses.

You can judge the attribute of memory foam

By the density of it's

whether or not it is temperature sensitive Density In case you cut a part of memory foam into a 12" cube and weigh it, you will know the density. In case the foam weighs 5 lbs. per cubic foot, it's called 5 lb. density and 4 lbs. per cubic foot would be 4 lb. density.

That is essential because the most perfect foam for supporting the body is 5 lb. and above. 4 lb. density is supportive but anything below 4 lb. is considered to be unfit for use in a mattress.

Lesser density foam mattress products will not last as long as the more compact variants so a 4 lb. foam mattress generally has a 10 year guarantee while the 5 lb. mattresses usually have a 20 year warranty.

Country of Production

American made while foam from China or elsewhere could be made using toxic chemicals that might be unhealthy, foams are manufactured to strict requirements.

Chinese foam is notorious for off-gassing and generating pungent scents which may endure for months. It's kind of like sleeping on Parmesan cheese.

I actually don't believe that's the recipe for the finest memory foam mattress.

You have to ask carefully if the foam is made in America because many producers state "Made in America" but neglect to inform you that they get their foam and also other raw materials from China.

ILD of the Foam

ILD is the measure of firmness of memory foam also it typically ranges from 8 to 20 for mattress foam.

A ILD of 8 would be too soft for most people while 20 would be too firm.

Most producers remain in the 10 to 17 range.

I do believe the huge "T" business uses and ILD of 14 for their 10" DeluxeBed(TM) so that will give you something to consider when determining your preference.

Temperature Sensitivity

The characteristic most well known about the very best memory foam mattress is of soften under you as it absorbs the heat from your own body, it is skill.

This fine tuning is important to get the maximum enjoyment out of your memory foam mattress.

There happen to be some makers who assert temperature sensitivity because of their foam but it necessitates extreme temperatures to change the foam.

You need to make sure when it absorbs the temperatures which can be generally linked to the human body, the foam will soften.

It is possible to determine this by checking to see if the foam is softer under your body and then lying down in the store for 5 to 10 minutes than it's outside the region where you are laying.

When you're shopping for the mattress merely do not forget the very best foam mattress will be 5 lb. density, made in America with an ILD of 10 to 17 and be temperature sensitive to 98.6 degrees of heat.
