I'm not sure if this is going to be a final rating.  I've had this pillow for about a week.  I had used a Level 1.0 pillow for two weeks at a relative's house and liked it which is why I ordered one. This brand new one seems stiffer, heavier and fuller than the one at my relative's house. I have tried sleeping on it every night but after an hour or so, I give up and go back to my old pillow. I wonder if the 0.0 would be better but I do like curved side.  I am a side sleeper.  Any suggestions?
