I’m not sure which mattress you mean by the “Bliss”.
Maybe it’s just too late at night for my brain to “unravel” the information :)[/quote]
No, it was too late at night for my brain to type the information. 
I meant to type “Pamper”, not “Bliss”. And I did it that least twice. I guess once I had “Bliss” in my mind, it wasn’t going to leave.
Pressure relief is easier for me to describe than alignment, as I had only my wife to tell me about the latter, and though she tries, she’s not an expert. She seemed to concentrate on my neck area, suggesting that when I’m on my side I’m not positioning my neck properly, seemingly regardless of the mattress.
As for pressure relief, the one that felt the best was the Nature with a 2" 14 ILD PLB topper. My shoulder seemed to sink in enough, yet my back still seemed to be supported enough – though I felt I could’ve used a bit more conforming around my lower back (I thought I still detected a small amount of tension there). (Try as I might, I really can’t seem to judge pressure around my hips, though. The day before I tried to spend 15 minutes on our Pamper without a topper, to feel the pressure on my hips. Instead I fell asleep for 30 minutes, and still didn’t feel anything after waking up. So maybe my wife is right that the hip pain is just from being in one position for several hours, and no mattress will cure that. Though I’d swear it seemed better when using that memory foam topper …)
I did not get the ILDs for the OMI layers I tried; they have them labeled simply as “firm”, “medium”, and “soft”. Though by squeezing the individual layers, it was easy to tell the difference between Dunlop with the same firmness label as a Talalay one (first time I’d tried that). The one I liked best had a Dunlop firm bottom layer, a Dunlop medium middle layer, and a Talalay soft top layer (the other choices they had set up were more firm, so I barely spent any time on those). The store was a bit crowded at this time, so I didn’t get to spend a lot of time on it to form much more of an opinion, other than it was the best of the OMI choices. But my shoulder didn’t seem to sink in far enough to be ideal as is. I didn’t get to find out if they had other layers I could try, but I hope so. As I wrote last night, I’d guess that my best choice would be a firm Dunlop base, a medium Talalay middle, and an extra soft Talalay top layer. But unless and until I can actually try that combination, it’s just a guess.
As for pricing, as I said (well, as I meant to say!), to upgrade from Pamper to Nature (not “Nature to Bliss”, good grief), would cost us $1250 plus, whereas an OMI with 2 Talalay and 1 Dunlop layer would cost almost exactly the same (about $100 less). (A Talalay layer costs $250 more than a Dunlop layer, so with 1 Talalay and 2 Dunlop layers it would be $350 less than the Nature. But I’m guessing a medium Dunlop would be too firm for me, and a soft Dunlop middle layer might not offer enough support – all conjecture, though.) The OMI of course has the advantage of being able to make changes like that, even a few years down the road. But the disadvantage is the warranty at just 10 years, and based on what you wrote, that’s because it just shouldn’t be expected to last as long as the PLB’s blended Talalay.
I hope this reply makes a bit more sense, though I realize it’s somewhat short on specifics.
