Started out great - after four years - not so good

Really comfortable at first, but after less than five years there were two impressions that made rolling over difficult. The euro-top lost all softness. Slightly better when rotated. Mattress looks like new except for the two impressions. After ten years with our last mattress, it was still like new. Bought a new house and thought we wold start with a new mattress. Should have kept our old Sealy. Replaced with another new mattress.
