Mattress Forum

I have a few questions for all the knowlegable out there.  The first one is where can I find places to test Latex mattresses in Los Angeles.  I have been to a bunch of different places and they all have one or maybe two mattresses, with dubious qualifications.  I would like to find a store or showroom where I can test a bunch of different beds, with differeing ILD's. 

The second question is can I find a latex mattress for under $1300?  Everything thats any good seems to be around the $1700 level.  Does anybody have any suggestions regarding places to look for something a little cheaper? 

Disregarding the mattress pad and cover, are ILD's of similiar type latex mattresses compositions the same?  What I mean by that, is if I go out and find a configuration that I like, can I expect somewhat the same feel if I order that online?  Thanks
