The problem is that while you may feel it bow/deflect, it wont show on the surface. A rep will come out and put a ruler over the bed and measure any deflection/sagging, and usually it will be within tolerance. The issue is what you will feel is the inner "rigid" core inside actually "deflecting", and that deflection does not transmit through to the surface due to that sort of material. A coworker of mine just did this prior to me pulling the trigger on the $500 mattress instead, im not gonna spend $2k on a mattress that gives in 5 years when I can spend $500 and get the same results, and hell, $500 ill just replace it once it does start to give, easily get my moneys worth out of that summabitch.
