After a recent stay at one of the Disney resorts, I wanted to replicate the plushness of the resort's bed. Our mattress is still in good shape (firm), so I didn't want to spend the money for a new pillow top mattress.  I considered a feather bed topper, but read they retain too much body heat.  So far, this mattress pad has worked out great! It adds the perfect amount of plushness to our bed, without making us hot or taking away from the overall firmness of our mattress.
