Welcome to the Mattress Forum! 
Subject to first confirming that any retailer or manufacturer on the list that you wish to visit is completely transparent (see this article ) and to making sure that any mattress you are considering meets the quality/value guidelines here ā¦ the better options or possibilities Iām aware of in and around the Greater Los Angeles region is in post #2 here .
