The Polyurethane Foams manufactured by Future Foams are tested in accordance with Australian Standard AS 2282.
Grade Identification
Future Foams grades are identified by an industry common coding system.
This coding system specifies a foams density and its hardness.
The first two numbers represent the density of the foam grade, and the numbers after the dash represent the hardness of the foam.
For example foam grade 30-130 has a density of 30 and a hardness of 130.
Density
The density of a foam refers to the weight of the foam in kilograms per cubic metre.
The density of a foam indicates a foams quality and durability.
The higher a foams density the more foam per cubic metre, thus giving superior comfort and support compared to a lower density foam.
Also higher density foams have less hardness and height loss.
The higher a foams density the higher the price.
Hardness
The hardness of a foam is a measure of the firmness or stiffness of a foam under load bearing.
Hardness is measured when a piece of foam is compressed to 40% of its thickness, and is the force (expressed in newtons of hardness) required to achieve the compression.
The hardness of a foam should not be mistaken for the quality of the foam, it is merely the firmness of the foam.
