Hi Dakota,
As you (hopefully) know from reading the tutorial I don’t make specific suggestions or recommendations for either a mattress, manufacturers/retailers, or materials because the first “rule” of mattress shopping is to always remember that you are the only one that can feel what you feel on a mattress. There are too many unknowns, variables, and personal preferences involved that are unique to each person to use a formula or for anyone to be able to predict or make a specific suggestion or recommendation about which mattress or combination of materials and components would be the best “match” for you in terms of “comfort” or PPP (Posture and alignment, Pressure relief, and Personal preferences) or how a mattress will “feel” to you based on specs (either yours or a mattress) or “theory at a distance” that can possibly be more accurate than your own careful testing (using the testing guidelines in step 4 of the tutorial) or your own personal sleeping experience (see mattress firmness/comfort levels in post #2 here).
When you can’t test mattresses in person then once you have decided on the types of mattresses you are most interested in then the only alternative to local testing is to talk with online manufacturers/retailers on the phone and in this case the options you have after a purchase to return or exchange a mattress or individual layers (just in case your choice doesn’t turn out as well as you hoped for) would likely become a more important part of your personal value equation.
I can certainly help you to narrow down your options, help you focus on better quality/value choices that are available to you either locally or online, help you identify any lower quality materials or weak links in a mattress you may be considering, act as a fact check, answer any specific questions you may have along the way that I am able to help with, and help with “how” to choose but only you can decide which specific mattress, material, or manufacturer/retailer is the best match for you based on all the parts of your personal value equation that are most important to you.
I’m not clear on which step you are “stuck” in the process but if you have a specific question I would certainly be happy to help.
