This is the best pillow I have ever owed. My should pain is gone (and it was bad), my sleeping is signficatnly better. I am able to fall asleep so mich faster from both going to bed and if I wake up during the night. I have considered purchasing a second one and keeping it in the cupboard when I need a new one in case they stop selling them. Actually life changing! My partner and a couple of friends have tried it and got it too.
