Density is a measure of mass per unit volume. This is expressed as kilograms per cubic metre (kg/m3). Density is the property that dictates the durability of the foam, in general terms the higher the density the better the foam will perform.
Hardness or firmness is a measure of the force required to compress a test piece to a specified percentage of it's original thickness, expressed in Newtons.The hardness factor is purely a matter of choice and can become very subjective.
