Hi domiagnew,
I understand but knowing the ILD of the layers won’t tell you anything about whether the mattress is a good fit or not unless you have a great deal of knowledge and experience with different latex mattress designs and different types and blends of latex.
There is more about the different ways to choose a mattress (locally or online) that can help you assess and minimize the risks involved with each of them in post #2 here but when you can’t test a mattress in person then the most reliable source of guidance is always a more detailed conversation with a knowledgeable and experienced retailer or manufacturer who can help “talk you through” the options they have available based on the information you provide them, any local testing you have done, and the “averages” of other customers that are similar to you. They will know more about “matching” their specific mattress designs to different body types, sleeping positions, and preferences and which of the firmness and layering options they have available will have the best chance of success than anyone else.
I don’t think you would find a local mattress that is similar enough to be a useful reference point and trying to choose a mattress based on “comfort specs” that have little meaning to you would be one of the more risky ways to choose a mattress.
