I had purchased down, bamboo and other pillows. But, the first time I laid my head on this pillow, I was in love!! It gives awesome support without sinking in or losing shape!  I love the cool gel.

Pros: does not lose shape. Supports without sinking in or changing shape.  It does not need to be fluffed up!!
Cons: It is heavier than traditional pillows.  The pros outweigh the cons!
