Hi richtj99.
Thank you for providing the specs of the system. Based on those specs, the components you listed are good quality and durable.
As far as the short time testing in the showroom goes… this will certainly tell you much more than if you did not try it at all. You can read more about this topic in this articlewritten by one of our experts (Beducator). If you focused in your testing both on comfort on monitoring your alignment for neutrality, even though you did not spend an entire night on the mattress you still have sufficient clues to determine the likelihood of this being a good mattress for you. Along with this, I would also make sure that any mattress you are considering has a good return/exchange policy just in case that things do not turn out as well as you hoped for.
It is good to remember that the first “rule” of mattress shopping that you are the only one that can feel what you feel on a mattress and there are too many unknowns, variables, and personal preferences involved that are unique to each person to predict how this mattress or would be for you in terms of “comfort”, firmness, or PPP(Posture and alignment, Pressure relief, and your own Personal preferences)or how the mattress will “feel” to you based on the specs that you are providing (either yours or a mattress), sleeping positions, health conditions, or “theory at a distance” that can possibly be more reliable than your own careful testing (hopefully using the testing guidelines in step 4 of the tutorial) or your own personal sleeping experience (see mattress firmness/comfort levels in post #2 here ).remember that you are the only one that can feel what you feel on a mattress
Good luck!
