Hi missy_,
If you have found the list for your local area (within about 50 miles or so) then it would already include the better options or possibilities I’m aware of in your area.
There are too many unknowns, variables, and personal preferences involved for anyone to suggest a specific mattress based on specs (either yours or a mattress) or theory at a distance that can be more effective than your own personal testing and experience (see mattress firmness/comfort levels in post #2 here). Only you can feel what you feel on a mattress.
If you follow the steps in the tutorial post one step at a time though about testing different types of mattresses to find out which types of mattresses and materials you tend to prefer and you also make sure that you know the type and quality of all the materials in any mattress you are considering so you can identify any weak links and make more meaningful comparisons to other mattresses then your chances of making a suitable and good quality/value choice will be very high. If you are looking at online options then the tutorial post includes several links to the better online options I’m aware of (in the optional online step) but the first step is to do enough testing so that you know the types of mattresses and materials that you tend to prefer.
I’m not sure which PLB mattresses you were testing but the specs of the current natural lineup are here.
The Mezzanine uses 1" of 15 ILD Talalay GL slow response latex on top of their bonded latex/polyfoam support core (see post #6 here). All of their mattresses use good quality materials and there are no weak links in any of their designs so it would only be a matter of choosing which one was the best “match” for you in terms of PPP and the parts of your personal value equation that are most important to you to decide on your “finalist” at that retailer. PLB is completely transparent about the type and quality of all the materials in their mattresses.
Unfortunately it can be very frustrating and a significant waste of time testing mattresses where you know ahead of time that you won’t be able to find out the type and quality of the materials inside it (see this article) unless you are willing to make a “blind” purchase where the odds are very high that there are lower quality materials in a mattress. No matter how a mattress feels or how good a match it may be in terms of PPP … there would be little value in buying a mattress which used lower quality materials that will soften or break down too quickly relative to the price you paid. There is more about the most important parts of the “value” of a mattress purchase in post #13 here.
The tutorial post includes a link to the better online memory foam options I’m aware of and several of these sell a mattress that would be similar to the Tempurpedic Rhapsody Luxe that use similar quality materials at much lower prices with good refund/return options as well. Most of them would be able to tell you which of their mattresses are closest to the Rhapsody Luxe and with a good return option you would be able to use your own personal sleeping experience to decide whether it was a good match for you in terms of PPP with little risk outside of the time and effort involved in returning it if your choice didn’t turn out as well as you hoped for.
