Hi floridamattress,
There is more about the most common “symptoms” that people may experience on a mattress in post #2 here but I would be very cautious here. The objective of every mattress is that it’s a good match for you in terms of PPP which stands for Posture and alignment, Pressure relief, and Personal preferences and I would prioritize them in that order. Based on your description (and correct me if I’m wrong) it sounds like you aren’t experiencing any “symptoms” and that the reason you are looking to exchange your mattress would be “comfort” issues which are very subjective and based on preferences. If your current mattress is keeping you in good alignment and provides good pressure relief then I would be cautious that the mattress you are exchanging for will do the same thing so that you don’t end up exchanging more subjective “comfort” or “preference” issues for posture/alignment or pressure relief issues.
Unfortunately I can’t feel what you feel or see you sleeping on the mattress and I don’t know anything about your body type, sleeping positions, history, or any of the other factors that may play a role in which mattress is best for you and there are too many unknowns, variables, and personal preferences involved for anyone (including me) to be able to predict whether a mattress is a good match for you in terms of PPP based on specs (either yours or a mattress) or “theory at a distance” (see mattress firmness/comfort levels in post #2 here). While I’m happy to help with questions about the quality of the materials … only your own careful and objective testing (hopefully using the testing guidelines in the tutorial post) or personal experience can tell you whether a mattress is a good match for you. There is also more about the most important parts of the “value” of a mattress in post #13 here.
When you are buying a mattress locally I wouldn’t pay any attention to whether a mattress is progressive or differential or any other “design theory”, or “comfort specs” and I would focus strictly on what your body is telling you with careful testing. Once you have confirmed that a mattress is a good match for you in terms of PPP to the best of your ability then the only specs you need to know are about the type and quality of the materials inside the mattress (and Fox Mattress uses high quality materials relative to their budget range in all their mattresses). I would let your body tell you which mattress is the best match for you in terms of PPP and then you can use your mind and the quality specs of the materials in the mattress can tell you about the quality and durability of the materials.
I can certainly confirm that all the materials and components in this mattress are good quality and there are no weak links in the mattress. In terms of PPP though … while the staff at Fox Mattress can certainly provide you with some good help and guidance … you are the only one that can know whether any mattress is a good match for you so I would make sure that if this is your only exchange that you spend some good “testing time” on the mattress you are considering.
