Mattress has lost its consistent density. Causes back ache every night/day

this mattress is very expensive, Im wondering what the difference is with the no name brands in BJ's etc. After about 2 mths the foam has lost its hardness and has become very inconsistent with the density of the layers of foam. This makes my husband and my back ache. Even my knees are aching...there are like soft marshmellow sections within the mattress. The edges have stayed hard, and so too the centre but where we lie (and we are a normal to low weight) seems to be sagging...not that you see that, but lie on the mattress and you can now feel inconsistent density of firmness...soft in some spots and harder in others....NOT GOOD FOR SUCH AN EXPENSIVE MATTRESS .
