Hi Trinitee64,
The better options or possibilities I’m aware of in the Ventura/Santa Barbara areas (subject to making sure that any mattress you are considering meets the quality/value guidelines here) are listed in post #2 here.
My best “general” suggestion would be to follow all the guidelines and steps in the tutorial one at a time.
I’m looking forward to finding out what you end up deciding … and of course any comments or any specific questions you may have that I can help with along the way.
