Hi barrysomgpark250,
You can read some comments about Essentia and some of the misleading claims they make and some forum discussions with them (as well as some of the FTC issues they have had about their claims) in this thread and this thread and posts #3 and #4 here). I certainly wouldn’t treat the information on their website as a reliable source of “fact based” information.
While they are clear that their mattress support cores are made from natural latex … as you can see from the posts I linked … I don’t believe that their “natural memory foam” contains any significant amount of latex.
