Make Sure You Buy the Right Foam for Upholstery

So you are looking for foam for upholstery. The things you have to look for are density and compression rates.

Compression is a measure of how much weight is required to depress the foam a given percentage. This test uses a standard round disc which is placed on to a piece of foam. The foam is then compressed to 75% of its original height and the pounds of pressure required to reach this point is the recorded compression or hardness of the foam. This does not necessarily indicate better quality foam but gives you an idea of how firm it is.

Density is the most important figure when purchasing foam. This number will indicate the weight of one cubic foot of the foam. Generally, as density increases, so does the quality of foam. So if one foam has a density of 1.1lbs/cubic foot and one 2.1/cubic foot the 2.1 is better. I have also seen 10 year warranties on foam. So ask for a warranty when you purchase foam and if there is none, ask why.

You must have a higher quality foam for the seats. So, when buying look for a high density rating of between 2 and 2.5 and then decide if you would like it medium or firm. For the backs and arms you do not need a good density foam because it does not get the use like the seats do. So a foam with a density between 1.2 and 1.5 will do just fine. If your backs are a pillow form you can use shredded foam. Normally when buying foam the more costly the better the quality. Make sure is passes the Cal. 117 flame test, but buy from a reputable dealer because it is not hard to advertise a 1.7 density and sell you a 1.3.

If you need foam for heavy equipment or snowmobile seats there is a foam called rebond or bond foam. This product is made from foam chips mixed with a high percentage of adhesive, under pressure, to make a very firm and dense foam. Density of these foams is normally 3 to 7 pounds.

When shopping for foam for upholstery make sure you make the right choice.
