Hi jkozlow3,
The better options or possibilities I’m aware of (subject to the guidelines here) in the Colorado Springs area are listed in post #3 here and for the Denver area are listed in post #2 here.
I would use two guidelines for this. The first is the recommendation of the manufacturer for that particular mattress and the second is which one is best for you in terms of PPP (any give in the foundation or support system will change the feel of the mattress). In very general terms most one sided mattresses will do best in terms of durability with a more solid foundation or platform bed with very limited flex or no flex at all since they can’t be flipped to compensate for the deeper continuous flexing in one direction which can cause the mattress to lose its shape and reduce the useful life of the mattress.
