Hi incognito,
You can see the criteria for organic certifications in post #2 here and in the case of latex an organic certification only requires that 95% of the materials in the latex product are organic. Latex manufacturers don’t disclose all the specifics of their compounding formula either to the mattress manufacturers that use their products or to consumers for competitive reasons so for for those that want to know the type of specific information that you consider to be important then these criteria would exclude latex as a purchase option which of course may be some people’s choice.
There is currently no specific definition of “natural” means or how it can be used in marketing although the NOP has some draft guidelines here that they are working on.
Mattresses can be fairly categorized as either “safe” or “unsafe” depending on the materials or the criteria you are using to define “safe” and some mattresses can promote deeper sleep if they are suitable for the needs and preferences of a particular person but it’s sleeping that is “healthy” (just like certain dietary or exercise habits) and not the mattress itself.
