Hi SoCalSleeping,
The better options and possibilities I’m aware of in the Greater Los Angeles region are listed in post #2 here.
If you haven’t already … I would also make sure you’ve read the mattress shopping tutorial here which has all the basic information, steps, and guidelines that can help you make the best possible choices.
Only you can feel what you feel on a mattress and there are too many unknowns, variables, and personal preferences involved for someone else to make a specific recommendation about which mattress may be best for you out of all the thousands that are available in the market so it’s really only possible to help with “how” to choose a mattress that is the best match for you in terms of PPP (Posture and alignment, Pressure relief, and Personal preferences) rather than suggesting a specific mattress or material (see mattress firmness/comfort levels in post #2 here).
There is also more information that may be useful for those in higher weight ranges in post #3 here and the posts it links to but in most cases it’s easier and more effective to have “just enough” information to be able to recognize the retailers or manufacturers that already know what you would otherwise need to learn. The knowledge, experience, and transparency of who you deal with and their willingness to put your best interests above their own can be one of the most important parts of a successful mattress purchase.
