Hi Sleepless in bflo,
This is a much more complex question than you may realize.
It also depends on how important an organic certification is for you for personal reasons and which parts of the mattress have an organic certification or even if the entire mattress is certified as “organic” (and there are very few that are).
The issue of an organic certification is also not the same as the separate issue of the safety of the materials in a mattress.
For those that are interested in the complex issues of “mattress safety” or who may have a different answer to the question of “how safe is safe enough for me?” than most people then post #2 here is a good place to begin your research.
There is also more about organic certifications for latex in post #6 here and organic certifications as a whole in post #2 here.
For most people though … making sure that the materials in a mattress have been tested for harmful substances and VOC’s and have a credible certification as being “safe” such as CertiPur (mostly used for polyfoam or memory foam) or Oeko-Tex (mostly used for latex) would be “safe enough”.
The only latex that is “GOLS certified organic” is 100% natural Dunlop but there is little to no difference between latex that 100% natural Dunlop or the same material that has an organic certification in terms of quality or performance although the certification does add to the cost of the material.
Cozy Pure is one of the members of this site which means that I think very highly of them (and Cheryl the owner) and I believe they compete well with the best in the industry in terms of quality, value, and service. You can see some of my thoughts about them in post #11 here and a forum search on Cozy Pure (you can just click this) will bring up more information and feedback about them as well.
