In December 2011 at Sears we bought a Sealy Posturepedic Candle Glow Ti2 Firm Euro Pillowtop, cal king.  After 4 months it has deep depressions (not enough for the warrenty which is 2 inches) and is causing me (a back sleeper) severe lower back pain.   I am past 90 days to return and less than 2" depressions mean no warrenty covergae.  Am considering a foam-ectomy.  Could I cut the top and remove the pillowtop foam?  Could I replace with latex 1" or will I need 2 layers of foam?  I need a firm mattress to sleep.  MArriot hotels always have nice beds, am #$%% off that we bought a dud.
