Now that memory foam has become popular there are many companies and distributors of this spaceage foam. The Sweedish Tempur Pedic brand is still one of the best brands out there, however, there are many cheap knockoffs as well as high quality off-brands. How can a consumer confirm the quality of these off-brands?
The quality of memory foam is based on many factors such as: the manufacturer, proprietary formulas and processes, density values, firmness determinations, and thickness. Most of these factors are beyond the ability of consumers to confirm putting us at the mercy of a salesman's pitch. However, it is possible for the consumer to confirm what many believe to be the most important measure of memory foam quality, density. Density values can be confirmed by the consumer with the use of two common household items, a tape measure and a bathroom scale. The instructions I detail here apply to those memory foam mattresses whose layers are not glued together. The Tempur Pedic brand has their layers glued together but don't worry, if you buy a Tempur Pedic mattress you don't have to confirm the specs, you can be assured it is a high quality mattress.
Foam Matress Topper
Some of the off brand mattresses do not have their layers glued together and if you choose to make your own memory foam bed like I did and buy all the layers separately, then these instructions apply to you.
The units of density are pounds per cubic foot. Your bathroom scale will be used to measure pounds and using a tape measure you can determine the cubic feet of your mattress. When I first received my memory foam layer I determined the density as follows.
1. Using a tape measure I measured the dimensions. This was queen size, my measurements were, 3 inches thick, 60 inches wide and 80 inches long. Now multiply theses three values, 3 x 60 x 80 = 14,400 cubic inches. Now cubic inches needs to be converted to cubic feet, just divide by 1,728 (because 1 cubic foot = 1,728 cubic inches, 12 x 12 x 12 = 1,728). Now, 14,400/1,728 = 8.33 cubic feet.
2. Using a bathroom scale weigh the memory foam layer. First weigh yourself and write it down. Then, while holding your mattress layer, weigh yourself with the mattress and write it down. These were my results, my weight = 165 pounds. My weight while holding the mattress = 198 pounds. Now just subtract, 198 - 165 = 33 pounds. This is the weight of your mattress layer.
3. Now just divide, 33 pounds / 8.33 cubic feet = 3.96 PCF (pounds per cubic feet).
Guess what? This layer I bought was supposed to be a 5 PCF memory foam layer. The company I bought it from either did not know their business or were trying to pass off an inferior product. I promptly called them and they agreed to replace it and pay all shipping costs. The replacement did confirm at 5 pounds per square inch. So consumer be wary and confirm the density value or your memory foam.
