Hi karen,
There is a list in post #5 here centered on Morehead city which has a few possibilities in New Bern but I haven’t talked with them so they would need some research to find out how much they know and can tell you about what is in their mattresses.
I took a quick look around Greenville, NC as well and there also isn’t a lot there but some of the possibilities that would also need some further research, along with the brands they carry that may have some better value include …

Southern Mattress, a Premium Economy Custom Mattress Manufacturer, Nationwide Delivery, Toll Free 1-800-227-8701 Rocky Mount, NC. Factory direct manufacturer that sells mostly wholesale to retail outlets but they also have a showroom at their factory that sells directly to consumers. They make some high quality traditional innerspring /polyfoam mattresses (including HR polyfoam) that are better quality and value than mainstream manufacturers in their price range. Very good quality and value in this style of mattress.

Kingsdown is one of the major brands that I would stay away from. Like most of the larger brands they won’t tell you any meaningful information about what is in your mattress and you will end up paying a lot of money foe a lot of polyfoam. Their MySide is very expensive for the type of materials they use. You could do a forum title search for “MySide” but it probably isn’t worth the time because they all basically say “very poor value”.
Bemco has some possibilities but it depends on which factory is using the brand. It is a licensee group and some factories that license the name and use it for name recognition for their own mattresses will tell you what is in their mattresses but others would require a lot of effort to find out any meaningful information about the mattresses that use the name. If the retailer can’t tell you all the layers and the quality specs of the foam layers (including the density of any polyfoam or memory foam) or doesn’t understand the importance of this information and you feel like you are “putting then out to get it” then I would pass them by. A forum search on “Bemco” (you can just click this) will bring up more information and the posts that mention them.
I think your best odds are in the other links I posted but if you make a few calls first in the Greenville area to “interview” the outlets I listed along the lines of this article, you may find some of the better local value there as well.
