Hi demiphonic,
I can certainly understand this 
While there are too many variables to suggest a specific brand or mattress (and how the materials and construction match your needs and preferences are more important than the brand anyway) … I can certainly help you with a process that can help you find your best possible choice.
Mattress construction theory and it’s interaction with human physiology and ergonomics can be a very complex subject to say the least and its study can lead to a learning curve that lasts a lifetime. Many of the concepts behind how each unique person interacts with different types of mattresses during sleep can also seem counterintuitive and it can take a lot of study and research to fully understand how all the many variables of how people and mattresses interact in so many different ways.
This is the reason that I normally suggest putting your initial efforts into some basic research and testing and then finding the manufacturers and outlets who already have this type of knowledge rather than trying to become an “expert” yourself or trying to design a mattress that may work for you using what I call “theory at a distance” based on either your own specs and/or the specs of a mattress.
The guidelines on the site are really only guidelines based on averages that are designed to help people ask better questions and better understand the accuracy or quality of the answers and the knowledge and experience of the people that are helping you. While they can be used to some degree by those who wish to take the time to study the theory behind them and take the first steps into designing their own mattress and then either making it themselves, having it made, or finding a mattress that matches their theoretical “ideal” to some degree, they are designed more to help you to know when someone is giving you “marketing” information or a “sales pitch” designed to “sell” you on a mattress that they want to sell you to boost their commissions or profit margins or if they really do have the knowledge and experience to educate and help you make your best possible choices. In other words they are designed to help you “find the experts” rather than become one yourself.
There are really only two ways to know which mattress, materials, or construction may be best for you.
The first is through personal testing, preferably with the help of a knowledgeable “expert”, and using the guidelines and their experience and knowledge of the mattresses they have available to help match your needs and preferences to a mattress that they sell.
The second is to work on the phone with an “expert” who knows every detail of the specific mattresses they make or sell and have the knowledge, experience, and customer base to make good suggestions based on the experiences of many other people with similar needs and preferences to you.
Both ways … finding the experts who make or sell mattresses is the most effective way of making your best possible choices. There’s more about this in post #2 here.
While I’m certainly happy to make more specific layering suggestions based on your experiences and feedback about a specific mattress with a known layering and construction and a specific set of “symptoms” on that mattress … the “best” suggestions about which mattress is best for you would come from the people who make and/or sell specific mattresses and have much more knowledge and experience than I do about the details of every component of their mattresses and the experiences and feedback of a large customer base on their specific mattresses as a guideline.
Did you mean “county” or “country”? If it’s a small county in the US or Canada… then I may know of some of the better possibilities near you if you can let me know the closest city or your zip. If you are in another country where I don’t know the better outlets or manufacturers that may be close to you … and you are considering an online or “on the phone” purchase … then the current list of recommended online outlets that I think highly of, are invited members of this site, and specialize in working with their customers on the phone, are in post #21 here.
Hopefully you have completed (and from the sounds of it you have) …
Step 1: Some initial research. This involves learning a bit about various mattress materials and components and layering and into finding some of the better local outlets that sell the types of mattresses and materials you want to test and will either tell you what is in their mattresses or where you already know from online research so you know what you are testing.
Next would be (if you haven’t already) …
Step 2: Actually testing various different types and styles of mattresses (in your case either latex mattresses or latex hybrids) enough to confirm the materials that you prefer in actual performance and feel compared to other types of mattresses and materials that are available to you. While latex certainly has many advantages over other materials and components, and like other materials and combinations can certainly meet your needs for pressure relief and posture and alignment, no matter what it’s strengths may be (and there are many) … unless it also matches your personal preferences then you may not be as happy with it or a certain layering combination or construction that uses it as “theory” may suggest in the long term.
Step 3: Connect with the experts (if you didn’t already do so in step 1 and 2) … either locally or online … and using their experience and knowledge in combination with your testing experiences talk with them enough to know which of their mattresses they would suggest for you and that you believe you would be most happy with in the short and long term. This is the step where you decide on the specifics and the “top choices” for each outlet rather than just the more general layering or material combinations that were the goal of step 2.
Step 4: is to carefully compare your few best choices in terms of materials, components, and all your needs and preferences (listed in post #46 here) and decide which ones offer the best “value” based on your personal “value equation” (the features, quality, and value of the mattresses that are your top choices, prices and your budget, the tradeoffs you believe are most important, and the services of the outlet both before and after the sale that are most important to you).
Step 5: is to make all the final most difficult decisions between “good and good” and close your eyes, grit your teeth, and make your final choice.
