I purchased this mattress less than 6 months ago and it feels like cardboard. Being newly married, first thing on the list was to purchase a new mattress, and we went to test out the models at Sleepy's. We ended up loving the Carolina Radiant Pillowtop, but were reluctant to spend the money on a brand that we had never heard of, but went ahead and got it. Sure enough, got the new bed delivered, and it felt like a totally different bed that what we had tried. 2 weeks in, and there were very noticeable dips where I lay and my husband lays, and I only weigh 100 lbs. I try to sleep in the middle of the bed to make it wear evenly, but literally roll down into my dip. Read online reviews and the manufacturer keeps speaking about the 'settling-in' period, so we tried to stick it out. Now approaching 6 months in we are sleeping in a hard 'W'. Making the bed makes me irate when I have to see the shape of the bed we just purchased- it is even noticeable through the down comforter, duvet and 2 blankets! If the bed needs to break in, why is the floor model in perfect condition? Very angry because we thought we purchased the mattress that suited us best. The garbage product that arrived was absolutely not what we paid for.
