When buying a "pillow top" mattress, do your homework. I wish I had. At the showroom, I tried a pillow top for about ten minutes. It was so very comfortable! Although the price was high, i felt that this would really meet my needs. Three months after the purchase, I felt like there was a weakness in the middle of the mattress. Three months later, the weakness showed when making the bed. It looked like a pothole! When getting into bed, I rolled into this weakness. Although I received a brand new mattress, I'm finding the same problem with this one. My suggestion would be to buy a regular mattress and then place a pillow-like top on the top. I understand from others than this is a flaw with pillow top mattresses.
