First night with the pillow and my arms didn't fall asleep!  When I lay down i feel like my back is aligned all the way down to my lower back.  It is the best sleep I have had in years.  I have used a standard neck pillow (roll on either side)for years and this new one is much better!  I bought one for my dad and he feels the same way.  Best sleep he has had in a long time.  My mom said it even made him snore less.  I love it and would suggest everyone who has been looking for that perfect neck pillow tries one of these.  Oh, and my hair isn't as messy when i get up.
