  Tempur-Pedic Mattress Comparison
Reporting on the latest space industry new has enabled myself, as well as the rest of the Space Daily staff, to witness some of the greatest technological advancements in the space industry. However, one of our most fond advancements has been the one we get to enjoy personally on a daily basis?the creation of NASA?s space age visco-elastic (also known as memory foam) used so widely in the bedding industry.

In case you might not already know, the leading company who produces visco-elastic foam mattresses is Tempur-Pedic?. They were the first to market NASA?s technology in the 1980s and the Tempurpedic mattress line has increased in market share steadily since. Over the last five years there has been an explosion in the bedding industry with many other mattress companies bringing their own visco-elastic foam mattresses to the market place.

However, it is unclear how many of these mattresses really offer a similar feel and quality that the Tempur-Pedic? brand image has been able to spring board off of. The feeling I am referring to, in case you have been living on Mars and haven't tried one out yet, is the sensation of your total body being supported as if the mattresses was being molded around you, only to have it slowly come back to shape after you roll over.

To be fair, not every person has felt that visco-elastic space age foam mattresses are the best choice, citing that they can often get too hot because of the lack of breathability that occurs with the very dense visco-elastic foam.

That is why we were excited to test out a new patented visco-elastic memory foam mattress called the Tempflow?, which claimed to offer a ventilation system to keep you cooler, while comparing in feel, support and comfort to the Tempur-Pedic? brand.

They did so by offering a design that uses many small ventilated holes that travel through the surface of the memory foam and exit through the convoluted airflow channel middle layer. While the patent pending design of the Tempflow? looked impressive, we wanted to take it one step further and actually compare side by side this new mattress to the TempurPedic mattress model that they believed it most directly compared to. They chose the Deluxe bed by Tempur-Pedic, so we ordered one of each for comparison testing purposes (the Deluxe bed has been renamed as the Tempur-Contour Signature since our original purchase, but the overall design is basically the same).

Upon inspection of the two mattresses, we noticed that the covers both seemed to be made of a stretchable, thinner velour material (since the time of this first article, Tempflow is offering an upgraded bamboo Kool-Flow? stretch cover and the Tempurpedic mattress below is currently using a Multi-Fiber knit cover). After removing the covers of both mattresses, we found a thinner socking material that we were informed was used to make mattresses fire resistant. Each mattress had an approximate one inch top layer composed of a softer visco-elastic foam, followed up by what appeared to be three inches of a slightly firmer visco-elastic foam.

The formally DeluxeBed (now Tempur-Contour Signature) has two layers of what appeared to be the same type of bottom base foam, while the Tempflow we tested had only one thicker bottom base foam layer. Both mattresses use a convoluted area on the surface of the base foam with peaks and valleys that enabled airflow to travel across them, although the Tempflow channels now use squared off peaks (presumably for more channel strength).

When I pushed on the surface foam for each mattress, I was able to feel air come out the sides of both mattresses at the convoluted side portions. However, with the patented ventilation technology of the Tempflow, I was able to also feel air come out the top through the many small holes in the visco-elastic foam on the surface, where as I could not feel any air come through the Tempur-Pedic visco-elastic foam surface. Then came the most important test of all, the direct comparison of lying on both mattresses and testing the pressure comfort, feeling of proper support, and temperature comfort.

After going back and forth from one mattress to another several times, I have to admit that I did not discern much difference in the memory foam sensation and overall mattress feel between the two mattresses. I also had several staff members perform the same test.

The best that I, as well as the other Space Daily staff members could come up with, is that the Tempflow? may start off feeling a bit softer initially, but both seemed to feel the same after lying on them for several minutes.

At that time I did not feel that I could make a decision about which one kept my body temperature cooler, as I knew that from my past experience that it may take several hours on a mattress to determine how hot it can get. So I did just that.

After splitting a night?s sleep on both mattresses, I was able to verify that the Tempflow? did indeed keep my body cooler overall. It is also a consensus from the other Space Daily staff members who have since slept on the two mattresses, that Tempflow? does indeed live up to its claim of being able keep the body cooler. Since the time of my first review for the Tempflow mattress, they have come out with three models and are now using what they call their Biogreen? memory foam.

One of their models, called the Eros?, uses this new Biogreen visco-elastic foam. It feels just a touch softer than our Tempur-pedic Deluxebed? (updated to the Tempur-Contour Signature) and in our estimation, it is somewhere between the feel of the Tempurpedic RhapsodyBed? and GrandBed?. For those that want a firmer feel than the Tempur-Contour Signature, Tempflow offers the Eclipse, Selene? and Copia? mattresses (the Eclipse being most similar to the original Tempurpedic mattress and the Copia being most similar to the Tempurpedic Rhapsody in configuration and feel). With the immediate softness of their Gaia? and Celestia? models, you will get that similar, instant reacting, plush comfort felt in the Tempur- Cloud? Supreme and Tempur-Cloud Luxe mattresses. For those that are looking for more of cross blended, hybrid type mattress, the newest Flexia model compares with the Tempur-Pedic Weightless Deluxe.

With so much green washing these days, it was nice to learn that the Biogreen memory foam has been independently tested by the same laboratory that heads up GreenGuard's certification testing (see UL laboratories tested the Biogreen memory foam for total V.O.C.s (Volatile Organic Compounds), which account for much of that initial smell that many people complain of when they first get a new mattress. In addition, the Biogreen foam was analyzed for many specific chemical emissions, such as phthalates, benzene, styrene, formaldehyde and many other dangerous substances. The results were that the Biogreen memory foam was shown to have approximately 13 times less in total V.O.C.s than the allowable requirements set from strict 3rd party environmental certification organizations, such as Certipur-US and Oeko-tex (00.039 parts per million to their 00.5 parts per million allowable level). It was also approximately 13 times lower than GreenGuard's Indoor Air Quality total V.O.C. requirements and approximately 6 times lower than Greenguard's most stringent Schools and Children total V.O.C. requirements. To go along with the Biogreen memory foam, the rest of the mattress uses a channeled resilient foam layer underneath the Biogreen memory foam, which has been Certipur-US Certified and a waterborne adhesive that is used to bond the layers and has been Greenguard certified. They also use a fire resistant outer socking material, which is free of dangerous chemicals, such as PBDE, Bromine and Boric acid, as well as being biodegradable. While both mattresses have been rated safe, we can't help but be impressed by the fact that the whole Tempflow mattress, not just the Biogreen memory foam, is an environmentally green way to go.

Both mattress The Tempflow? uses a patent pending technology that allows companies show their airflow to circulate through the foam via a patent pending ventilation confidence in the system. New to the Tempflow model is their proprietary Biogreen? longevity of the memory foam. See for more information about mattresses by offering how their technology works. 40-year limited warranty for the Tempflow? and a 25- year limited warranty for the Tempur-Pedic? mattress. Both companies offer a sleep trial to ensure that you are completely satisfied you?re your purchase, but the Tempflow? offers a 120-day sleep trial, as compared to Tempur-Pedic??s 90-day sleep trial.

Needless to say, my staff and I agree that this new patented technology that the Tempflow? uses, really offers a way to get the feel and support of the leading brand and very popular Tempur-Contour Select model from Tempur-Pedic?, but with a cooler airflow ventilation system.

Therefore, we unanimously decided to give the Tempflow? visco-elastic foam mattress our Space Daily product innovation award for making excellent use of NASA?s space technology for home use and bringing to the market place a new, innovative technology that really works.
