Hi jrolex,
Post #2 here lists the local manufacturers in the Dallas area (and there is one more in post #4). The one that is a member here … The Mattress Factory … is currently not open while they take their annual vacation but I also think highly of the other two choices I have talked with.
A look through their websites and/or a phone conversation will tell you what they offer in your preferred materials and also give you a sense of what to expect when you visit them.
Post #21 here has a list of the members here which specialize in online sales. All of them are very good at helping their customers make the best choices for their needs and preferences and all of them are great value for different reasons although they include a wide range of different styles and price ranges. Not all of them make or sell memory foam but a look at their sites or a phone call (some don’t list everything on their site) will tell you which ones do.
Post #12 here includes some of the better options for online memory foam mattresses including three of our manufacturing members.
Hope this helps
Phoenix
