The jury is still out...I can not call it a comfortable pillow, but I have had no neck pain...that's the plus.  The negative is that there is an odor, probably from the shredded foam, that is difficult to get rid of.  I have aired it out for 3 days and used aromatherapy spray, but it still has an odor...disappointed.

Pros: No neck pain
Cons: Odor
