Foam density is a specific measurement of how much weight in pounds polyurethane foam can handle per cubic foot. This density rating tells you the strength of the foam. The higher the number the longer the foam will last. Foam's durability and lifespan also depends on amount of pressure and usage it gets.

 

The thicker the foam, the firmer it will feel. Additionally, keep in mind when deciding on the firmness of your foam that under heavy use, after 6 months to a year, upholstery foam will break in and soften up to about 20%-30% over time. If it will get very seldom use, the original firmness may never soften.

 

Currently, the following high density foams are available for custom cuts...

1.8 Soft, 1.8 Medium, 1.8 Firm, 2.5 Medium-Firm
