Hi MauleGuy,
Welcome to the Mattress Forum! … and I’m glad you found us 
While I can’t speak to the “comfort” of a mattress or whether a mattress is a good match for you in terms of PPP because your own careful testing (hopefully using the testing guidelines in step 4 of the tutorial) or personal experience is the only reliable way to know … outside of PPP the most important part of the value of a mattress is it’s durability and a mattress is only as good as its construction and the type and quality/durability of the materials inside it regardless of the name of the manufacturer on the label.
If you can find out the information listed here about the layers and components in both of the mattresses you are considering and post it on the forum then I’d certainly be happy to help you compare them to the quality/durability guidelines here and let you know whether I can see any obvious weak links in the mattress that would affect the durability and useful life of the mattress. Without this information it’s not possible for me to make any meaningful comments about the quality or durability of any mattress.
As you can see in my comments in the Seattle list here … based on my previous conversations and experience with them the staff at Bedrooms and More is certainly knowledgeable and experienced and should be able to provide you with all the information you will need about the type and quality of the materials in their mattresses to make an informed choice.
There is also more about the pros and cons of two sided mattresses in post #3 here but they can certainly make a more durable choice than a one sided mattress that uses the same comfort layers on only one side of the springs.
