Hi BeachMac,
I don’t make specific suggestions or recommendations for either a mattress, manufacturers/retailers, or materials because only you can feel what you feel on a mattress or decide on the types of mattresses and materials that you are most interested in trying or that you tend to prefer and there are too many unknowns, variables, and personal preferences involved for anyone to be able to predict which specific mattress design or combination of materials would be “best” for you based on specs (either yours or a mattress) or theory at a distance (see mattress firmness/comfort levels in post #2 here) that can possibly be more reliable than your own careful testing or actual sleeping experience. What is “best” for you either in terms of a mattress or a manufacturer/retailer can be very different from what would be “best” for someone else.
I can certainly help you narrow down your options by helping you know how and why to avoid the worst ones and with “how” to choose or act as a fact check or answer specific questions you may have along the way but not with which specific mattress, company, or manufacturer to choose.
Two of the more important links in the tutorial that I would especially make sure you’ve read are post #2 here which has more about the different ways to choose a suitable mattress that is the best “match” for you in terms of PPP (Posture and alignment, Pressure relief, and Personal preferences) that can help you assess and minimize the risks of making a choice that doesn’t turn out as well as you hoped for that are involved in each of them and post #13 here which has more about the most important parts of the “value” of a mattress purchase which can help you make more meaningful quality/value comparisons between mattresses in terms of suitability, durability, and value.
If you are attracted to a latex/innerspring hybrid then post #2 here may be helpful as well.
When you can’t test a mattress in person then the most reliable source of guidance is always a more detailed phone conversation with a knowledgeable and experienced retailer or manufacturer that has your best interests at heart and who can help “talk you through” the specifics of their mattresses and the options they have available that may be the best “match” for you based on the information you provide them, any local testing you have done or mattresses you have slept on and liked that they are familiar with, 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 than anyone else (including me).
