Hi mechanic,
It would be great if that was possible but unfortunately nobody else can feel what you feel on a mattress and there are too many unknowns, variables, and personal preferences involved for anyone to know for certain which mattress will be the best “match” for you based on specs (yours or a mattress) or “theory at a distance” (see mattress firmness/comfort levels in post #2 here). Having said that … most of the better online manufacturers are very good at providing good guidance with a more detailed phone conversation with you based on the “averages” of others that appear to be similar to you. For a large majority of people this would end up being a suitable choice and if your mattress is a component mattress then with the options you have after a purchase to rearrange or exchange layers you would be able to fine tune the feel and support of the mattress even further so the odds of success are high.
All of this assumes that you are familiar with how latex feels and performs but if you haven’t slept on latex before then I would definitely pay them a visit if for no other reason than to feel what latex feels like and so you can also feel the difference between Dunlop and Talalay to see which one you prefer (see post #7 here).
As you probably know … SleepEZ is one of the members of this site which means that I think very highly of them and that I believe they compete well with the best in the industry in terms of their quality, value, service, and transparency.
A mattress is one of the most important purchases you can make in terms of the effect it will have on how you feel and your overall well being and it’s not something where I would take “shortcuts” since your decision will affect you for the next decade or longer. You are fortunate to live in Phoenix where there are more good options than most other cities in the country and if I was in your shoes I would definitely take a few hours to do some testing. Of course these types of decisions are always up to each person’s “best judgement” and “risk tolerance” along with where you are in the range between “I can sleep on anything” and “princess and the pea” and the parts of your personal value equation that are most important to you.
