What is High Density Foam?

High density foam is used for many different things. From mattresses to cushions and case inserts, you may not always see it, but chances are you use it daily. The cell structure of this foam is very compact. It is known to be hard-wearing and sturdy.

Many people believe that the density of foam and its firmness are directly related. This is not the case. Foam with a high density can feel firm or soft. The way we determine density is via its weight per cubic foot.

Calculating Density

The way to calculate the density of a piece of foam is to divide its weight by the value of the length, width and height multiplied. The calculation looks like this –

Weight ÷ Width x Height x Length = Density

Density is generally determined by measuring one cubic foot of a piece of foam. To classify as high density, the calculation must be more than 6 pounds per cubic foot.

High density foam generally lasts longer than foam with a lower density. For this reason, it is often used to make cushions in high-quality pieces of furniture. The higher the density, the heavier the foam. Because of the greater volume of compressed material, it breaks down at a slower rate.

We stock a wide variety of foam grades with high densities. When ordering foam cut to size, you will be able to choose from multiple different types to suit your preference.
