Hi theresamquinn,
Just for the sake of clarity … there is no such thing as organic Talalay … only Dunlop. There is more about organic certifications in post #2 here and more about the different types and blends of latex in post #6 here. All the latex that you are likely to encounter (whether it’s Dunlop or Talalay or made with natural, synthetic, or organic rubber or a blend) will all have been certified for VOC’s and harmful substances by either Oeko-Tex standard 100 or by Eco-Institut so they would all be “safe” materials.
