Hi epiksleeper,
There is no “correct” or “incorrect” or any mattress that is “the best choice” … there are only mattresses that are “best for you” regardless of whether anyone else would make the same choice. Nobody else can feel what you feel on a mattress and there are far too many unknowns, variables, and personal preferences involved for anyone else to be able to know which mattress is the best match for you based on specs (either yours or a mattress) or theory at a distance (see mattress firmness/comfort levels in post #2 here).
There is more about the most important parts of the value of a mattress purchase that you can use to compare the different mattresses you may be considering in post #13 here.
I would also keep in mind that if you prefer a “foam” support core over other types of support core (such as an innerspring support core for example) or “foam” comfort layers over other types of comfort layers (such as microcoils or natural fibers for example) that there are different types of foam (polyfoam, memory foam, latex foam) that are all very different from each other so you may love one type of foam in either comfort or support layers and not be comfortable at all on another type of foam (not to mention that there are many firmness options and many different versions of each type of foam). All that “foam” means is a material that has air bubbles inside it and almost every mattress you will encounter has some type of foam in it somewhere … usually in the upper layers.
The most effective way to choose a mattress that is “best for you” is to follow all the steps in the mattress shopping tutorial one at a time which can help with “how to choose” (nobody else can tell you “what to choose”) and I would always make your choices based on your own actual testing and experiences and knowing the type and quality of the materials inside it instead of going by “theory” or by other people’s experiences that may be very different from your own.
There isn’t a list for the McAllen, TX area and the closest list would be in the Corpus Christi area in post #4 here which is some distance away.
The only “good” option I’m aware of in the McAllen area is Denver Mattress® - The Easiest Way to Get the Right Mattress in Pharr, TX. They are a regional manufacturer that makes a wide range of mattresses including innersprings and their iChoice models which include a “mostly latex” and a latex/memory foam hybrid. They are transparent about the materials they use in their mattresses and are good quality/value compared to most mainstream choices. I would avoid the major brands they also carry.
Over the course of the next few days and time permitting … I will take a look in the area to see if I can see any other options or possibilities that may also be worth considering.
