Hi richmanja,
You can read a bit more about both Anatomic Global and so called “ecofoams” or “plant based foams” in post #2 here and in post #2 here.
They can be “better than average” value but knowing the quality and value of any mattresses depends on the willingness and ability of the retailer to tell you the details of every layer of the mattress (including the foam densities) and to help you understand what they mean. Without this there is no way to make any meaningful assessment of comparison of any mattress and you would be making a “blind” purchase.
I would also make sure you have read post #1 here and the information, guidelines, and steps that are included. It is the single most important post on the forum when you are looking for a new mattress. It also includes information about how to test a mattress more objectively for what call PPP (Pressure relief, Posture and alignment, and Personal preferences) so that you don’t just test a mattress for “showroom feel” or “subjective comfort” which is among the worst ways to choose a mattress.
Hope that helps … and if you find out the specifics of the layers of the mattress you are looking at (and providing this is part of the job of every good salesperson) and post them here I’d be happy to give you more of my thoughts about it.
