Density
Usually expressed in pounds per cubic foot. Higher density often correlates with greater durability and resistance, but formulation matters.
ILD
Indentation load deflection measures firmness/resistance under a standardized compression test. It is frequently used to describe latex layer firmness.
Why shoppers should not collapse them into one number
Two latex layers can differ in density, ILD, thickness and process. The finished mattress then adds quilting, other comfort layers and a support core. Use density and ILD as specifications, not as complete predictions of comfort.
