The density of your memory foam topper refers to the amount of foam it contains per cubic foot. In order to imagine how the different densities would feel against your body, Imagine hands that are supporting you in bed.
In such a scenario a 5 pound density uses 5 hands to support you. Meaning that a higher density memory foam has more hands to support you than a 3 pound density would have for example. This means that the 5 pound will last much longer because there are more hands to do the same work, its team work. That is why the 5 lbs will easily last for 20 years.
Next we want to compare the density with the original product that was developed by NASA & designed for the astronauts, now used by Tempur-Pedic ®. They studied and tested various densities before coming up with the 5 pound. In their opinion after years of testing this is the best formula for Longevity, support and contouring.
You may ask how we know all this, one of our customers is a scientist that worked on this project, and he shared this information with us. Many companies on the net claim to be selling 5 pound density memory foam. Here is a way you can tell for yourself
1-Get the size & weight of the pad.
ONE CUBIC FOOT = 12" x 12" x 12" = 1728 CUBIC INCHES
CUBIC FEET OF FOAM = (LENGTH X WIDTH X HEIGHT) Divided by 1728
DENSITY = WEIGHT OF PAD Divided by CUBIC FEET OF FOAM
Like anything else, you get what you pay for........
Our toppers are different than the Chinese made,lightweight, 3 lb. or 4 lb. low density memory foam, gel foam bed overlays you find at Costco, Walmart, Zellers, Jysc...
Our 5 lb/ft³ memory foam toppers are:
Next, we want to compare the density, with the original product that was designed for the astronauts by NASA, and now used by Tempur ®. They studied and tested various densities such as 3 lb. or 4 lb. memory foam before coming up with 5 lb/ft³. In their opinion, after years of testing, the 5 lb density is the best formula for Longevity, support, contouring and pressure relief. Our 5lb memory foam pad topper will work on almost any bed surface, as long as your mattress is firm, strait, and in good condition.
It's important to note that foam density is not an exact science. The standard accepted in the foam industry for 5 lb density memory foam is anywhere from 4.5 lbs to 5 lbs.
