Hi CentralPA,
No … if the type and blend of the latex was the same then an organic certification wouldn’t change anything about the material. There is more about organic latex in post #6 here and organic certifications in post #2 here. The certification is costly and adds to the cost of the 100% natural Dunlop that is being certified but outside of the fact that it is certified there is really no difference between the materials.
The only type of latex that has an organic certification is 100% natural Dunlop and if everything else was the same then there would be no difference in durability between 100% natural Dunlop and the same 100% natural Dunlop that had an organic certification.
There is no organic Talalay latex … only 100% natural without an organic certification.
I think the main reason that people would choose organic Dunlop would be for personal reasons and because they would feel more comfortable knowing that the raw latex was produced on an organic farm using organic farming methods and that the latex core was manufactured using organic certified facilities and methods.
