Hi SOFTMATTRESS,
The better options or possibilities I’m aware of in the San Diego area (subject to the quality/value guidelines I linked in my last reply) are listed in post #2 here.
I would also keep in mind that there are also no “standardized” definitions or consensus of opinions for overall firmness ratings and different manufacturers can rate their mattresses very differently than others so a mattress that one manufacturer rates as being a specific firmness could be rated very differently by another manufacturer. Different people can also have very different perceptions of firmness and softness compared to others as well and a mattress that feels firm for one person can feel like “medium” for someone else or even “soft” for someone else (or vice versa) depending on their body type, sleeping style, physiology, their frame of reference based on what they are used to, and their individual sensitivity and perceptions. This is all relative and very subjective and is as much an art as a science. There are also different types of firmness and softness that different people may be sensitive to that can affect how they “rate” a mattress as well (see post #15 here).
The only way to know for certain whether a mattress feels soft or firm to you or whether it fits your criteria will be based on your own personal testing or experience.
