Dunlop vs. Talalay Latex

You may have heard OMI refer to our two lines of mattresses as “certified organic” or “100% natural.” What exactly do those terms mean, and what are the differences between the two? The difference is in the method of manufacturing the latex and the organic certification process: organic Dunlop vs. natural Talalay. Our Certified-Organic Mattresses are made using Dunlop latex only, whereas our 100%-Natural Mattresses are made using Talalay latex. The two processes both start with a botanical sap. However, the Dunlop we make our mattresses out of begins with a USDA-certified sap, whereas Talalay does not.

Extracting Rubber Sap:

The rubber sap that is used to manufacture both Dunlop and Talalay latex is harvested from sustainable plantations in Southeast Asia. The sap is extracted by cutting the bark of the rubber tree to allow the white sap to flow out. This method allows the tree to heal rapidly, and is the eco-friendly alternative to cutting down trees for latex extraction. Each tree can yield latex for up to 30 years, and is then harvested for furniture wood. The land is then replanted.

The Dunlop manufacturing process was created in 1929, and was the first method developed for producing latex. The USDA (United States Department of Agriculture) certified-organic rubber sap is whipped into a froth (to aerate), and is then poured into a mold or onto a long conveyor belt. The latex is then slowly steam-baked into its solid state. Originally this process produced denser, less uniform latex, but over time the method has been refined to produce the even, consistent latex we use today. The finished core is then certified to GOLS (the Global Organic Latex Standard), allowing us to make 100% certified organic mattresses as the end result.

The Talalay family developed the Talalay manufacturing process during World War II. This method adds two additional steps to give the latex a more consistent cell structure: After the sap is whipped into a froth (to aerate) and poured into a mold, the mold is vacuum-sealed and the latex flash-frozen to keep particles from settling. The latex is then flash heated into its solid form.

The addition of these two steps (vacuum sealing and flash freezing) in the Talalay method is the main difference between Dunlop and Talalay, besides the organic certification and purity assurance. Many people still associate Dunlop latex with being a denser, less consistent product, but this is simply no longer true. Both methods have been refined over time to produce the uniform and supportive latex we use at OMI.

Should Americans Fear Their Furniture?

James Redford and Kirby Walker, directors of “Toxic Hot Seat” at Napa Valley Film Festival in California

Airing tonight on HBO is a documentary that explores the chemical-laden flame retardants contained in much of today’s furniture.

Here is an excerpt from the article, Should Americans Fear Their Furniture? by New York Times author Jane Margolies:

The pet hairs and red wine stains on sofas across America, it turns out, should be the least of our concerns. The real issue is what is in the foam cushions we curl up on every day: up to two pounds of flame retardants.

In their HBO documentary “Toxic Hot Seat,” scheduled to be aired on Monday, the directors James Redford and Kirby Walker disclose that these chemicals, as used in home furnishings, do not stop fires. They do, however, whoosh out of seat cushions when we plop down, hitching a ride on airborne dust and ending up in our bodies. They have been linked to cancer and other health disorders.

The film explores how a 1975 California law requiring retardants (Technical Bulletin 117) became widely adopted. And it follows the firefighters, scientists, health advocates, state legislators and investigative journalists who brought attention to the chemicals, leading to a recent reform of the California mandate — which the directors, who spoke from their homes in the San Francisco area, applaud.”

This issue was previous explored in the OMI blog “Makers of Flame Retardants Manipulate Research Findings.”

We at OMI continue to use a safer system that allows us to use organic wool as our only flame retardant. As a result, our mattresses are able to pass federal flame tests without the use of toxic chemicals or silica barriers. To use any form of chemical flame retardant in our products would violate our ethical standards and integrity. We stand by our purity so you and your family can have a safer place to rest your heads at night.
