Hi jazzycat,
Some of the better options and possibilities I’m aware of in your area (and in Charleston, Columbia, and Hilton Head) are listed in post #2 here.
While there are latex mattresses available in your area … none of them are component mattresses that I’m aware of either but there are several of these available in the Charleston area (including one of the members of this site).
I’ve talked with Scott from Foam Sweet Foam on many occasions and as you mentioned I do think highly of them but there are many manufacturers or retailers around the country that I think highly of and that are included in various forum lists around the forum that for various reasons haven’t yet chosen or decided that the timing was right (or in some cases been invited) to become a member … yet. There was another reply here yesterday that had the same question about another manufacturer. (NOTE: They are now a member of this site).
The mattress shopping tutorial includes a link to the members here that sell online which includes many that make or sell a wide range of latex or latex hybrid mattresses (including component mattresses) with different designs, options, features, and benefits in different price ranges.
They all make mattresses that use high quality materials (different types and blends of latex) and that have no “weak links” in their designs but they all have different options, designs, prices, and return or exchange policies. Savvy Rest is sold factory direct but also through a larger group of retailers across the country so they provide the option to test their mattresses in person for more people (for the others you would need to be local to the manufacturer) but they are also in a higher price range and the level of knowledge and experience at each Savvy Rest retailer may vary. All the others are factory direct and are all knowledgeable and experienced and provide good service and guidance to their customers. There is more in post #13 here about the most important parts of the “value” of a mattress purchase but outside of the specific differences between the designs and materials and pricing with each of their mattresses … the differences between them would depend on all the parts of your personal value equation that are most important to you.
