It cuddles my back no,alter what side I am sleeping on.  I have bad back pain, turn multiple times throughout the night  and must keep a pillow inbetween my knees to keep my spine straight.  With this pillow, I don’t have to move a separate pillow with me when I turn to put inbetween my knees.  One surprise was how HUGE it is - very unexpected!!  Where do you store it once you make the bed??!
