It is a little too thick to sleep on. At least for me. I am used to having a smaller/less thick pillow and sleeping with my head pretty flat. But the ghost pillow is perfect for propping up to read in bed. Very Comfortable.
Finally I found a pillow that does not make me toss and turn at night. It is comfortable and is cool. It also supports my neck and head. I would recommend this pillow for a good nights sleep.
