Description
Most seat cushions are made using Polyurethane Foam. IPS Foam fabricates and sells polyurethane foam in a variety of densities and compression ratings. We are a wholesaler so minimum order sizes do apply. We sell to the furniture industry, marine industry, packaging industry, pillow, sports and recreation industry, insulation, medical industry, and more.
Foam is measured by two standards: density and compression, or Indentation Load Deflection ILD rating.
Density refers to the amount of material in one cubic foot of foam; the denser the product, the more the cubic foot will weigh.
Compression refers to the amount of force required to compress that cubic foot by 25 percent.
The two figures together describe the softness to hardness of the foam. For example, a 2735 rated foam is 2.7 pounds per cubic foot and requires 35 pounds of pressure to compress it 25 percent. This is a medium-firm foam suitable for couch cushions.
If you want your cushions a bit softer, as you would for a back cushion, you could use a 2720 foam, which would be much softer, requiring only 20 pounds of pressure to compress it 25 percent. Very dense foam — 4 to 5 pounds per cubic foot — can also be found with low compression ratings. This is typical of very high-density memory foam, which is a specific poly foam and could have a rating of 5314, for example.
WHAT MAKES A GOOD POLYURETHANE FOAM?
There are three performance tests that are of primary concern in evaluating the suitability of foam. The first concern is if the foam is rated as HIGH RESILIENT (HR). The next concern is the DENSITY rating of the foam. And finally, the INDENTATION LOAD DEFLECTION (ILD) rating is of equal importance as the foam’s density rating.
