Spring Air Evolution Memory Foam Mattress Set Reviews

For any Spring Air evolution memory foam mattress set material to be considered "visco-elastic" it needs to be able to be sensitive to pressure and temperature and be able to return to its original shape after having pressure applied to it. It’s graded by its weight and its ILD Rating (Indentation Load Deflection), resilience, and tensile.

The polyurethane foam’s weight is determined by the amount of chemicals that are included. The more chemicals that are included the more visco-elastic and the more dense the spring air memory foam becomes. The density, however, is not determined by hardness. A Spring Air memory foam mattress and other units by other manufacturers have weights of anywhere from 2 pounds to 3, 4, and 5 pounds.

The ILD Rating tells you precisely how soft or how hard a Spring Air foam mattress is going to be. Using a fifty square inch indentation the ILD rating of twenty-five percent is the required number of pounds for a twenty-five percent compression of four inch thick foam. An example of this to make it seem less complicated is as follows: If a quality memory foam mattress takes twenty pounds of pressure to make a twenty-five percent indentation then the foam has a twenty pound ILD. Simply put, the more firm the foam the higher the ILD.

The resilience of a Spring Air memory foam mattress reviews or any other unit is measured by a steel ball’s percent rebound after it is dropped from a thirty-six inch height. If you read that a mattress has HR foam then that means it is highly resilient and it gives a high steel ball rebound reading. A general rule of thumb is that the higher the resiliency the more durable the foam.

The tensile of a mattress is an indication to how far the foam can be stretched which is measured by pounds per square inche, and how far it can be stretched before it tears. This is a reading/value that is normally not applied to a Spring Air Memory Foam mattress because they do not require stretching.
