Do you know anything about Diamond Mattress Co ? I think the mattresses are made here in California. They sell at a retail store called Oak Liquidators.
Hi burly,
You can read more of my thoughts about Diamond Mattress in post #2 here and the two posts it links to. Like any mattress regardless of brand they are only as good as the specifics of their construction and the quality of the materials inside it and in some cases it may be difficult to find the information that allows you to make meaningful comparisons and informed buying decisions.
