Hi Need2PullTheTrigger,
I wasn’t planning to add to the thread because you didn’t want to do research and I don’t suggest specific mattresses for people (there are too many variables and unknowns to use “theory at a distance” or other people’s suggestions or reviews as an effective way to choose a mattress design or comfort level that is “best” for you) but I thought I’d jump in to caution you that you may be fairly deep into the “buyer beware” side of the industry. Some online merchants don’t list their materials accurately, will list foam densities per 2 cubic feet, add up the densities of several layers and list them as a single density, or list numbers in their descriptions that don’t relate to density at all (for example the 3.3, 5.5, and 6.5 listed here by Allsleep (Cloud 9) have nothing to do with foam density even though it’s clearly meant to imply to customers that it does). The PURgreen certification also doesn’t list what it tests for and is basically meaningless. I would ask some very specific “point blank” questions about the specific density of every layer in the mattresses you are looking at and also make sure you know the actual shipping weight of the mattress so you can check them to make sure they are close to being right.
PPP means Posture and alignment, Pressure relief, and Personal preferences which along with the durability of the materials and your personal value equation are the basics of how to choose a mattress that is “best” for you.
