Hello.
I am searching for a holy grail memory foam-type layer (2" or 3") that is both relatively safe to use and not overly warming (i.e., is relatively breathable).
I have been able to locate a couple that are Greenguard Gold certified (more stringent than Certipur, from what I understand). Is this the best I can get? I have heard that there are some (overseas) that are even Oeko-Tex 100 certified? Thank you.
