As with any bedding product, especially pillows, it takes some getting used to these pillows. Most folks get very attached to old worn out pillows and I'm no exception to that thought process. After getting a new Tempu-Pedic mattress, it was time to change out the pillows. You body gets accustomed to certain things and doesn't always react well when it comes to changing your sleeping environment. Long of the short is, I'd recommend these pillows, though they are very pricy, but worth it in the long run. Most important thing is to give them a bit of time - especially if you add or remove the filling, at least 2 months or more so your body will adjust. Since these are adjustable, store any excess filling in a zip lock bag for later use.
