Hi Jenniferleah,
There are some retailers in Waco that carry some latex hybrids or some mostly latex mattresses (using blended Talalay) but for what you are looking for I would head in the direction of Austin and visit Bob at Sleepworld who carries a wide range of latex mattresses (including organic latex) and is the closest to you that I’m aware of. There are other natural or organic options in Austin as well that you can use as a value reference for comparison. The Austin list is in post #2 here. I don’t think any of the 4 Dallas/Ft Worth manufacturers listed in post #4 here make a mattress like what you are looking for but they may be worth calling as well just to make sure.
Some of the members here that specialize in online sales also make and sell mattresses that use either natural or organic latex and organic wool quilted covers and you can also use these as a value reference as well. They are listed in post #21 here.
Hope this helps.
Phoenix
