Hi cliffw42,
You are fight in the middle of the Houston, Corpus Christi, San Antonio triangle but I haven’t done any research into Victoria, TX. There are no manufacturers there that I’m aware of.
EDIT … added: The better options in the Houston area are in post #2 here.
The better options I’m aware of in the San Antonio area are listed in post #2 here. Both of these would be my preference over Corpus Christi.
Since you are quite a distance from all of these … I’ll take a look tomorrow to see if there is anything more local that would be worth including in your research so the forum can have a Victoria, TX list as well and make up for the “gap”

ADDED: I did some searching in the Victoria, TX area and out of the choices I saw … probably the only local retailer and the manufacturers they carry I would visit are …
http://www.mattressdepot.us/victoria.htm# Victoria, Corpus Christi, Cedar Park, Portland, Kingsville, TX. They carry Eastman House (not on their site but I talked with them) and their house brand made by Sleep Designs. Has 4 Eastman models including a latex hybrid and one that has latex, memory foam, and microcoils. As always … it’s important to make sure that you know the details of all the layers and components in any mattress you are considering.
Unfortunately there are not a lot of great choices in the immediate area.
