Over the years, I have always had issues with pillows as I have a neck and spinal problems. So I chose to have the adjustable pillow with the cooling effect. (It's summer now!!) I did take some of the filling from one pillow, as I felt it was too high for my neck support. I left the other one as is. I alternate each night, and the truth is, they are both very comfortable. I do get a good nights sleep. I am happy with my purchase and my choices. No complaints!!
