Hi adler223,
Electropedic is one of the better options in the LA area (which is why I included them in the Los Angeles list here). They have a fairly wide range of mattresses including several 2 sided latex options in different designs which are among the better quality/value choices in the area.
In my conversations with Electropedic I have always found them to be knowledgeable and helpful both about their mattresses and about adjustable beds in general (which are an area of specialty for them). A forum search on Electropedic (you can just click this) will also bring up more comments and feedback about them.
