Talalay and Dunlop Latex


Latex can be found in many different products in the form of natural or synthetic.  The synthetic form of latex is derived from petroleum, while the natural form…you guessed it…comes from nature!  Many plants produce natural latex, but the Pará rubber tree produces the liquid latex used in the majority of commercial applications.

Talalay and Dunlop are the two methods used to make liquid latex into a core for a latex mattress.  So what’s the difference between the two processes?  It boils down the heating and cooling (no pun intended).  Talalay is a process of vacuum pressurization, flash freezing and heating followed by several washes.  With the Dunlop method, liquid latex is poured into molds, heated and washed, and does not have the flash freeze step that the Talalay goes through.  Both processes have been improved in recent years to yield a more consistent product.


Another development in latex is the Global Organic Latex Standard, or GOLS.  This standard establishes sustainable processing methods from organic raw materials and also addresses standards for the health, safety and welfare of workers during the manufacturing process.  This new organic certification is available only with Dunlop latex, and everyone here at OMI couldn’t be happier to have more assurance and another step in purity.
