Why We Choose The Dunlop Process
Harnessing The Power of the Elements
Compounding - Compounds are made only from 100% natural latex, tapped from a rubber tree with no fillers or additives
Vulcanizing - Steam cure technique creates core engineered with thousands of stainless steel pinholes of the right size and shape to give the most efficient vulcanization. This makes our latex comfortable and durable . These pins keep the natural latex characteristics undisturbed through the vulcanizing process.
Washing - A multi-cycle washing method using drinkable quality water ensures clean and pure latex mattress cores.
Drying and conditioning - Drying and conditioning by drying mechanism is enhances the natural feel of the product and eliminates all residual moisture.

Understanding I.L.D. Measurements
We offer the following latex ILDS: Soft: 18-22, Medium: 23-27,
Firm: 34-38, and Extra Extra Firm 45-49
I.L.D., or Indentation load deflection is measured by putting a 15x15x4 specimen of latex in a machine known as an indentometer and measuring the weight required to push the latex down to different levels of compression. The three step process reads in order of normal pressure (25% compression), extreme pressure (65% compression), and then back to normal (25% compression.)
The indention level is calculated according to pressure divided by thickness to help provide an explanation of how much weight each density naturally holds. When customizing remember that stacking cores with different density readings provides unique results. An I.L.D. rating of 10 lbs. at 25% means that it takes 10 lbs. to compress the foam 25%. At 65% the I.L.D. rating changes dramatically and will have a significantly higher figure thanks to the materials natural reflex. After compression at 65% readings are retested at 25% to ensure proper reflex. 25% is generally the I.L.D. rating for a person of normal body weight and the reading that we generally use to categorize our latex.
Today I.F.D, or Indentation force deflection, is used interchangeably with I.L.D. Know that both mean the same thing and are used interchangeably. Choosing latex density and reading firmness levels is easy, just remember that ideal indention levels should be at around 25% for the most longevity.
Firmness vs. Density
DENSITY - A Lbs. per cubic foot is simply the DENSITY of the latex and is not related to I.L.D. at all.
Foam or latex can have a high I.L.D. with low density and conversely a low I.L.D. on a high density material when comparing to others.
Remember that choosing I.L.D. has nothing to do with quality, it merely indicates the softness or the hardness of a piece of latex and is another tool for you to understand the testing that has already been done on your mattress core to ensure proper manufacturing.
