Hi plasticpitchfork,
Unfortunately there isn’t because there are just too many unknowns, variables, and personal preferences involved in choosing a mattress that can make each person unique and very different from someone else … even if they have the same general body type.
The only two ways to choose a mattress are either careful and objective testing using the testing guidelines in the tutorial post (which are different from just testing a mattress for “subjective comfort” which can have lower odds of success than random chance alone) along with the guidance of a knowledgeable and experienced salesperson that has your best interests at heart or if you can’t test a mattress in person then a more detailed conversation with a knowledgeable and experienced online manufacturer or retailer that can help “talk you through” which of the options they have available would have the best chance of being suitable for you based on the averages of their customers.
If you don’t have confidence in the choice you are making (either locally based on your testing or online based on a more detailed conversation) then the options you have after a purchase to fine tune the mattress or exchange or return it would become a more important part of your personal value equation and the “value” of your purchase so that you can lower the risk of making a choice that isn’t suitable for you and use your actual sleeping experience to confirm whether a mattress is a good match for you in terms of PPP (Posture and alignment, Pressure relief, and Personal preferences).
Based on the information in your previous posts and some of the “challenges” you are facing in choosing a mattress … I would start with a visit to Quality Sleep / My Green Mattress and then go from there. If nothing else you will be much better informed about the types of mattresses that will likely be most suitable for you and you will have a good baseline that you can use to compare other mattresses.
