Hi ja58,
Hopefully you’ve had the chance to read the mattress shopping tutorial which has all the basic information, steps, and guidelines that you will need to make the best possible choices.
I would keep in mind that your body can’t “feel” the “ahhh” or the “wow” factor when you are sleeping and that the most important part of healthy sleeping is that a mattress keeps you in good alignment and relieves pressure in all your sleeping positions (see post #13 here). Looking for the the “wow” factor can often lead to choices that may not be the most suitable for you when you are sleeping.
I would also keep in mind that while latex is a great material … not everyone prefers it and one of the goals of testing mattresses is that it can help you find the materials and types of mattresses that you tend to prefer. Any combination of good quality materials and components can be suitable for some people and not for others and it’s not unusual that the materials that someone may “want to like” are not the same as the materials that they actually end up preferring in real life.
Unfortunately nobody else can feel what you feel and there are too many unknowns, variables, and personal preferences involved for anyone to use specs (either yours or a mattress) or "theory at a distance to predict which mattress would be the best match for someone else in terms of PPP (Posture and alignment, Pressure relief, and Personal preferences). This is the part of choosing a mattress where your own personal testing will tell you more about the materials and types of mattresses that you tend to prefer than anything else (see mattress firmness/comfort levels in post #2 here).
You have many good options available to you and if you follow the steps in the tutorial post one by one and use the information and testing guidelines that it links to you will have the best possible chance of choosing the mattress that is the best “match” for all the parts of your personal value equation that are most important to you.
