How is foam density calculated?

In other words, the density of foam is expressed by measuring the weight of a single cubic foot of foam material. By dividing the total weight by the total number of cubic feet (100 divided by 25, in this case), we can see that this layer has a density of 4 pounds per cubic foot (4 PCF).

Is high density foam comfortable?

High-density foams are mostly used as a core layer. But in some instances, especially for mattresses built for support needs, they can be used as a comfort layer. This is especially great for stomach, back sleepers, and heavy people.
