The two main things that define a foam are its density and IFD. Density is simply how much weight a foam has. It is measured by weighing one cubic foot of foam. The higher a foams density, the better quality it is. The IFD (Indent Force Deflection) is just a measurement of how hard or soft a foam is. The lower the number the softer the foam. You can see the Density and IFD of our foams by opening the material specs PDF file.
