Hi MattressShopper26,
Post #9 here includes the better options and possibilities I’m aware of in and around the Fredericksburg area and should be helpful 
I can only speak to the quality and value of a mattress and your own personal testing and the guidance of knowledgeable and experienced retailers and manufacturers who are most familiar with their own mattresses is a much more accurate way of making the most suitable mattress choice than any “theory at a distance” I could offer. There are just too many variables to choose the most suitable mattress based on height / weight and sleeping position information alone.
Having said that … Cozy Pure is a member here which means I think very highly of them and consider them to be among the best of the best in the country. They make some very high quality mattresses with good value … especially for those who are more focused on natural and organic materials. Cheryl takes exceptional care to use only the best quality materials (down to the last thread) in all her mattresses. You can see my thoughts about them in post #11 here and a forum search on Cozy Pure (you can just click this) will bring up more feedback about them including some feedback with pictures from one of the members who purchased from them in this thread.
Hope this helps and if you have questions along the way that I can answer don’t hesitate to ask
