When comparing different types of foam with other companies, it is most important to look at the density and ILD of the foam.

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. It should not be used exclusively as a sign of durability or comfort, because the firmness and lifespan of foam products just like mattresses and cushions depend on many factors, including density. The density may vary slightly between each foam shipment.

The ILD or IFD measurement shows how hard or soft the foam is. The higher the number, the more firm the foam. AIt also represents how many pounds the foam will hold before it collapses. If you take a 12″ x 12″ x 12″ foam cube after the certain ILD is reached that foam will collapse.

We vacuum pack the foam to reduce shipping costs. You will have to give the foam 1-2 days to return to its original shape. It will look a little misshaped and not measure to correct size until after it expands.
