The Talalay process is a highly controlled and a very sophisticated latex manufacturing process that produces the finest quality and most consistent latex mattress components available in the world. The Dunlop process is the more commonly used production method worldwide. It creates a more dense and firmer product that is most often used as a base core for many popular latex mattress designs.
The major difference between the two processes is what happens inside the mold just before to the initial latex curing stage. In the Talalay manufacturing process a much smaller amount of latex compound is poured into the mold. Air is then extracted to perfectly distribute the foamed liquid inside the latex mold and to create a consistent round and open cell structure. The mattress core is then flash frozen to lock the cell structure into place and to prevent the particles from settling thus creating a very uniform finished latex core.
In the Dunlop latex process, the molds are filled to the top, air is not extracted and there is no flash freeze stage like in the Talalay process. Therefore, the latex cell structure is less airy and thicker. This process produces a heavier product and gravity takes over settling the particles to create a more dense product than than does the talalay process however I have seen talalay poured into configurations that I consider to be rock hard making talalay more versatile than dunlop. Talalay latex is available in a much wider firmness range so it can provide enhanced comfort choice for consumers around the the world.
Over the last 10 years the Dunlop process has been improved drastically and now the debate is on over which is actually better, the Talalay latex or the Dunlop latex. My years of experience tell me that heavier people who also sleep on their backs are a perfect match for an all dunlop latex mattress where lighter folks and those of us who sleep primarily on our sides, the talalay latex works better for.Watch this interesting video that takes you from the harvesting, to mold injection, to finished process of a natural latex mattress core.
