Hi stevelb,
Post #2 here includes many of the better quality and value manufacturers and outlets in the greater LA area.
Custom Comfort makes some very high quality mattresses with good construction although in “value” terms they are in a higher more “premium” price range than some of the other similar choices on the list. I would certainly choose them over many other more “mainstream” outlets or brands but there is probably better “value” on the list for the needs and preferences of most people. Flexus Comfort is one of the manufacturing members here which means that I invited them to become members because I believe they make some of the best quality/value mattresses in the country.
You are fortunate to live where you do because you have some great choices available to you in all the different types of mattresses.
