Hi Uunderr,
The link to the mattress shopping tutorial is on top of the right hand column of the page and is also in my signature at the bottom of all of my posts. The online lists are linked in the optional online step in the tutorial.
The better options or possibilities I’m aware of in and around the Greater Los Angeles area (subject to making sure that any mattress you are considering meets the quality/value guidelines I linked in my last reply) are listed in post #2 here.
