The Stearns and Foster Pillowtop firm mattress cost us over $2000.00 and is a saggy piece of crap with a hump in the center.  Flipping does no good.  I'd like to flip it over a cliff.  What a huge disappointment.  I toss and turn constantly and have lower back pain throughout the day and night. 

This is an overpriced, lousy product.  Never again. 

I am now researching a replacement mattress and am leaning to a Memory Foam. I'll let everyone know how that goes...
