Hi yogiyoda,
I haven’t personally seen the law tags because Essentia isn’t available in my area but those who have, have told me that it says “polyurethane”. Essentia also didn’t choose to post their law tags when I asked them to do so in the other thread when it would have been very easy to prove their claims (of course their Dunlop latex they use in the base would be listed as latex).
Chemical analysis of their “natural memory foam” also doesn’t show evidence of natural latex and is indicative of an MDI based polyurethane (MDI and Polypropylene Glycol) such as made by the manufacturers mentioned in the other thread I referred to.
Since you appear to be quite interested in Essentia and have a “tendency” to believe their claims, I would take the time to do some searching about them to read what has been posted and to read the conversation I had with them in another thread and some of the links that it leads to. You will quickly see that they are more about marketing than they are about “truth in advertising”.
Many people find their mattresses very comfortable and they do use latex (Dunlop) as part of the support components but their “natural memory foam” is not what they claim. I and many others have also tested MDI based memory foam and they don’t have the typical offgassing of most TDI based memory foams. As I mentioned some of them are Oeko-Tex standard 100 certified. My issue is not with their use of polyurethane but in the accuracy of their claims, their marketing methods, and that that people are buying an expensive story that just isn’t true believing that what they purchased is “latex”.
