I first experienced the Core pillow in my acupressure dr.'s office.  I loved it.  I loved it so much I took it out of its pillowcase to see who the manuf was.  But when I got my brand new pillow, I found that it was too thick for me.  I'm 5'2", petite, and we were not a good fit.  The ones in the dr's office were "broken in" and felt good, but I think it would take too long for the new one, and in the meantime, I was feeling neck and back strain so I returned it just today.  Sorry, but not for me.
