Now that the cat is out of the bag due to the toxicity levels of many memory foam products, interest in all natural latex foam products has increased. I thought it would be nice, as I am an industry professional, to explain the differences in latex mattresses and the different types of processes used to create these alternative and special beds.
Origin of latex rubber
Brazil provided the world with the rubber tree, Hevea Brasiliensis. In 1876, the British government exported seedlings to London for further development. From there, the seedlings were exported to Sri Lanka and Indonesia, where they flourished and the extraction technique was discovered. Over the following Latex, the British in Sri Lanka and the Dutch in Indonesia cleared vast amounts of rain forest to create today's rubber tree plantations.
What is latex?
By definition, latex is a rubber particle suspended in water. There are 2 types; NR or natural rubber and SBR (styrene butadiene rubber) or artificial latex. All latex is a mixture of the two or 100% natural latex.
What is the difference between Talalay latex and Dunlop processed latex?
The Talalay process is a highly controlled and sophisticated latex manufacturing process that produces the most consistent and highest quality latex available in the world. The Dunlop process is the most widely used production method worldwide. Create a firmer product that is used more often as a basic base component.
The main difference between the two processes is what happens in the mold just before the initial stage of latex curing. In the Talalay process, only a small amount of latex compound is poured into the mold. Air is drawn to perfectly distribute the foamed liquid within the mold and to create a consistent round and open cell structure. The mattress core freezes quickly to lock the cell structure in place and prevent particles from depositing.
In the Dunlop process, the molds are filled to the brim, no air is removed and there is no freezing stage. Therefore, the latex cell structure is less "aerated". This process produces a heavier product. Gravity takes over the sedimentation of the particles to create a denser product than the Talalay process. Talalay latex is available in a much wider range of firmness, so it can provide a better comfort option for consumers around the world.
What are the benefits of latex mattresses?
Latex foam mattresses instantly adapt to each unique contour of your body for exceptional orthopedic support and pressure relief. They have been shown to provide 33% more pressure relief and contouring support than memory foam. One thing I notice when I go to bed with memory foam is that I feel like I am being swallowed and it is difficult to move with my back to my sides. It is like climbing a hill. I also sweat a lot more than usual when I put memory foam on. My problems seem to be widespread among other memory foam users. Those problems just don't apply to latex foam mattresses.
The soft, compliant support of latex foam reduces high pressure areas that interrupt capillary blood flow and cause a person to move and turn. This relieves pressure and helps carry oxygen and nutrients to the muscles, so you wake up feeling recharged and refreshed.
Latex beds are naturally healthy. They are antimicrobial and resistant to dust mites to alleviate allergies. They have improved breathability and provide resistance to heat and humidity. Elimination of disturbing sleep transfers, so you can rest easy even if your partner is restless. My children often jump into my bed trying to wake me up. Unless they fall on me, I don't even know they're there.
