Hi Phi8lOster,
I think you may be going somewhat overboard and entering a “rabbit hole” of never ending and more and more detailed information in your “safety research” … especially considering that the mattress you are considering makes no claims about using either natural or organic materials. This is the type of research that you generally won’t find answers to the degree of specificity that you may be looking for or that may be completely satisfying to you unless you raise your budget considerably and look for mattresses that only contain natural or organic materials.
There is more information in post #2 here and the more detailed posts and information it links to about safe, natural, organic, “chemical free”, and “green” mattresses and mattress materials that can help you sort through some of the marketing information and terminology that you will encounter in the industry and can help you differentiate between them and answer “how safe is safe enough for me” or “how natural is natural enough for me” so you can decide on the types of materials you are most comfortable having in your mattress or on the certifications that may be important to you. These types of issues are complex and are generally specific to each person and their individual sensitivities, circumstances, criteria, beliefs, and lifestyle choices.
The only official list of Oeko-Tex certified materials is the Oeko-Tex site.
All the latex you are likely to encounter (Dunlop or Talalay made with either natural or synthetic rubber or a blend of both) will have been certified by either Oeko-Tex or Eco-Institut for harmful substances and VOC’s (see post #2 here) and in general I would consider any type or blend of latex to be a “safe” material.
Latex International is now called Talalay Global but you can see their Oeko-Tex certification here.
Mountaintop Faom announced that their latex was Oeko-Tex certified on their facebook page here but I don’t see the listing in their name on the Oeko-Tex site so you may want to email Mountaintop to find out the certificate number since it may be listed under another name. ADDED: You can see the certificate number here
[quote]Also spoke to someone at Jones Fiber, who makes their Fire Retardant material which is “cotton, inherent fR rayon, and low melt polyester.” even though Brooklyn Bedding talks about being made in the USA, Jones Fiber told me they get the materials for this fabric “from wherever is the cheapest” not necessarily the USA.
Heard that the production of rayon includes some pretty nasty chemicals. Any thoughts on that re: this FR fabric? [/quote]
You can read more about their Jones fire barrier in this topic. Again … if it was me I would have no concerns with the “safety” of their fire barrier however you may have criteria that are much more stringent than most people in which case it may be worthwhile looking at mattresses that only contain natural or organic materials and components,
