After searching for years I have found the best pillow I've ever slept on. I am a side sleeper and found this pillow to have the perfect amount of fill that you can still scrunch it for side sleeping but I've also noticed I've been sleeping very comfortably on my back as well. It doesn't sink so much that you feel like there is nothing between your head and the mattress like other pillows I've used in the past. When I sleep on my side it scrunches very nicely under my neck to support it and my head so that I am sleeping more level now than before. No more back or neck aches. My daughter tested it for just a few minutes and thought it was heavenly and will probably get one for her birthday.
