i sleep on my back so the pillow doesn't work for me, if you are used to memory foam pillow it is not for you. i guess my head is just too damn heavy and the pillow doesn't have any substance that can hold my head from the bed whenever i lay on the pillow. It is almost like lying on the bed without pillow except having some fluff on both side of your cheeks. my husband sleeps on his belly, he said it is all right for him. i didn't return it because of the price, the pillows look on king bed.
