Hi ddcfri,
[quote]Is there an update to information about the Eco 3 mattress as far as densities are concerned?
Please let me know if you found out anything more about how this mattress is actually constructed.[/quote]
I don’t have any additional information about the Eco 3 and I don’t seem to be able to get consistent information about the Anatomic Global mattresses. Having said that … all the versions of the information I did receive indicate that they don’t use any memory foam below 4 lb density. I also don’t know the density of their polyfoam base layers. About the best I can say is that for most people that aren’t in higher weight ranges there probably wouldn’t be any obvious weak links in the mattress in terms of the quality/density of the foam (you can see the density guidelines I would suggest in post #4 here). Unfortunately … Anatomic Global doesn’t seem to be particularly forthcoming about their foam densities.
FXI foams are CertiPur certified* so unless you had a specific reason to believe otherwise such as a known sensitivity or medical condition such as MCS that would cause you to avoid memory foam, for most people the “safety” of their foam wouldn’t be an issue. If hypothetically there was a safety issue with a particular type of foam in terms of VOC’s then an inch of another type of foam on top of it wouldn’t make any difference because you would need to use something around the entire mattress to either absorb or block the VOC’s (see post #3 here) and quite frankly I would avoid any mattress which I believed presented that type of safety issue.

There are too many variables, unknowns, and personal preferences involved to use use a formula or “theory at a distance” to predict whether a mattress would be a good match for you in terms of PPP. Only your own testing or experience can know this with any certainty with or without an additional inch of latex. Nobody else can feel what you feel on a mattress (see mattress firmness/comfort levels in post #2 here).
