Hi nosamk,
Yes … I’m certain that there is no Talalay latex that is certified organic. If a retailer is claiming that their Talalay is certified organic then all you would need to do is ask them to show you the organic certification (which of course they won’t be able to provide). While some of the components in the mattress may be certified organic (such as the cover or the quilting) any Talalay latex in the mattress wouldn’t be.
There is more about the different “levels” of organic certifications in post #2 here and more about organic certifications in general post #2 here. There is also more about GOLS certified organic latex in post #6 here.
All latex will have some initial smell that will dissipate and reduce over time and all materials will have some degree of “offgassing” (even fruits and vegetables have a smell which is “offgassing”) but all the latex you are likely to encounter (either Dunlop or Talalay and made with either natural or synthetic latex or a blend of both) are certified for harmful substances and VOC’s by either Oeko-Tex or Eco-Institut and by most people’s criteria or by any reasonable standards all of them would be a very “safe” material.
There is also more about allergies (which are usually to dust mites or other particulate allergens) and methods that can be used to control dust mite populations or other allergens that can be related to mattresses and bedding in post #2 here and in post #3 here. There is also more about allergy encasements in post #2 here.
There is more about the most important parts of the “value” of a mattress purchase in post #13 here which which can help you make more meaningful quality/value comparisons between mattresses in terms of suitability (how well you will sleep), durability (how long you will sleep well), and the overall value of a mattress compared to your other finalists (based on all the parts of your personal value equation that are most important to you).
While you are the only one that can feel what you feel on a mattress so I can’t speak to which of the mattresses you have tested (hopefully using the testing guidelines in the tutorial) would be the most comfortable or would be the best “match” for you in terms of PPP (Posture and alignment, Pressure relief, and Personal preferences) … you are certainly looking at some very qood quality options and in terms of durability none of them have any lower quality materials or weak links in their design.
