Hi rzailit,
Good idea that should eliminate most of the variables. Like you said … don’t mess with a chemical engineer. I’m really curious what your results will show.
Sometimes it really seems to be hit and miss. We also had a bad experience with a memory foam topper on one occasion and it was both of us with similar symptoms and not just the smell. It wasn’t pleasant to say the least. It’s the only time I’ve reacted to memory foam. The smell itself was kind of “musty” which I understand is typical of aldehydes but you would probably know more than I would on that front.
There are two parts to an organic wool certification. One of these is the farming of the sheep and the production of the raw wool which is controlled by the NOP of the USDA. They don’t have an organic certification for the wool products or textiles though and for this you would need to look for GOTS organic certification. There are also non certified wool textiles that don’t use chemicals such as eco wool or Puregrow wool. There is an interesting article here on organic wool.
Unfortunately they no longer have a showroom but they may be able to give you some guidance about testing similar mattresses at Lake Mattress (see post #19 and 20 here). I would call them first though as there appears to be some confusion in their relationship or agreement which I still haven’t been able to clarify.
Post #2 here may also have some other options close to you where you can test latex.
