Hi Thomas_MAurer,
It may help to read the two threads in the forum about the misleading claims that Essentia is making. One of them is here and the other is here (where they actually registered on the forum and made some comments but then disappeared like they have in other internet forums when the questions started to get more specific and “difficult”). One of these threads was actually active today.
I would strongly recommend doing more in depth research and taking their claims (and many others as well) with many grains of salt before recommending them based either on the comfort of their mattress (which is an individual preference) or the claims on their website (which are suspect at best).
