I got the extra firm cooling pillows. The extra firm is exactly what it says been 4 months and still not breaking these pillows in at all. They're comfortable, quiet, and heavier so you don't have to chase pillow around the bed. The cooling part isn't worth the extra money, my bamboo pillows retain less heat than these. Overall nice pillow, If I were to drop another $150 on pillows id probably return to bamboo.
