It works but it's not firm enough for my needs.
I have 3 fusions in my neck and needed some support on the arch of my neck so I went straight to this firm pillow.  I am a bag sleeper so this worked well for me.  However after a week of use, the support under my neck started to get soft due to the material on the inside moving.  It’s still better than a regular pillow so I’m still using it but perhaps a rolled up towel will give me the same support.
