LATEX MATTRESS CORE FACT SHEET

Standard Hardness Specifications for Mattress Cores
Hardness Range (ILD= Indentation Load Deflection)
Soft 19-22 (natural=20-24) ILD
Medium 26-30 ILD
Firm 30-34 ILD
Extra Firm 34-38 ILD
Super Firm 42-46 ILD (blended only)

Hardness range measurements based on ASTM D-1055.

ILD is a firmness measurement (ILD= Indentation Load Deflection) and is a standard for measuring foam firmness.

It is also called IFD, or Indention Force Deflection . It is a measure of load bearing capacity or firmness. IFD is measured on the surface as 25% IFD For example, to determine 25% IFD, a four-inch thick latex sample is compressed to three-inch thickness. the number of pounds required to achieve compression is the 25% IFD value. The higher the IFD, the firmer the surface feel.

Special Compression ranges available upon request.
