Hi dnobes,
Thanks for the kind words … and I’m glad you found us.
Hopefully you’ve had the chance to read the tutorial post which has all the most important posts in the forum all in one place about choosing a good quality and durable mattress with no weak links in the design or materials, knowing what to look for and what to avoid, and testing a mattress to make sure it’s a suitable choice for you in terms of PPP (Posture and alignment, Pressure relief, and Personal preferences).
Post #3 here and the posts it links to also has more information about choosing a mattress for those who are in higher weight ranges.
While a trip to Dallas/Ft Worth would certainly not be wasted because there are some good options there in the Dallas/Ft Worth list (including The Mattress Factory which is one of the members here) … … it’s also a long way to drive both ways and there are also some good options and possibilities in the Austin and San Antonio area that are listed in post #2 here that should be helpful
