The PFA is a good resource for those wishing to understand all the gobblegook about density and ILD

Especially the INTOUCH newsletter.

Density, measured in pounds per cubic foot, is a key property for determining flexible polyurethane foam performance.
Foam density is independent of foam firmness.
Density relates to the comfort, support and durability properties of the foam.
Density can be affected by foam additives or fillers. To truly gauge foam performance, the unfilled, or polymer density of the foam must be evaluated. Polymer density takes only the weight of the basic foam materials into account.
Foam fillers and additives are used to improve the combustion performance of the foam, to make the cushion feel heavier and more luxurious, or to improve support, but may have a negative effect on other foam properties.

Sorry I saw you post, I know it is quite old but I would like to know more, What exactly is Polyurethane? and how well does it hold up?
