The best way to cut the open-cell foam is with a sharp knife or electric carving knife. Just repeat in one direction to get a clean cut. Please note that if you order these size sheets they may be bigger than the actual size listed and rough around the edges in which you may have to cut down.
When comparing different types of foam with other companies, it is most important to look at the density and ILD of the foam.

Why spec range? When foam bun is made it has a slight variance on density and ILD so that is why our spec sheet has a range. You would not feel the difference unless you compare side by side. Normally our density and ILD is in the middle of the range. For example, Luxury and Premium is 2.8lbs density, and Luxury is a 50ILD and Premium is a 35ILD.
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. Firmness and lifespan of foam products like mattresses and cushions depend on many factors that are not just limited to density of the foam. Please note: the density of our foam may vary slightly between each foam shipment.
ILD or IFD measures the firmness of how hard or soft a foam is. The higher the number of the foam is, the firmer the foam is. This also represents how many pounds the foam will hold before it can and will collapse.
ILD/IFD Example: when using a block of Luxury Firm High Density foam 12″ x 12″ x 12″ the ILD for that particular foam is 50. If you put an item that exceeds 50 lbs onto the foam then the block of foam will collapse and compress to the bottom.
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.
