Hi jmatt101,
Just in case you haven’t read it yet … I would make sure you’ve read the mattress shopping tutorial here.
I would keep in mind that the name of the manufacturer has nothing to do with the quality or durability of the materials in a mattress since all of them have access to the same sources of latex. Outside of PPP … a mattress is only as good as its construction and the quality of the materials inside it regardless of the name of the manufacturer on the label.
You certainly won’t have to travel out of state since you have some great options available to you on the Los Angeles Region list (and there are others in the San Diego list here as well).
