The Tri Core family of pillows is the way to go. Another great pillow but definitely for those of us who like a harder pillow. One of the most common types of pillow someone is looking for: hard or soft. The TriCore firm pillow is the one for you if you like a neck pillow that's a little more firm.
Keep in mind a neck pillow will be slightly more firm in the neck roll normally. They are built this way to maintain the neck roll to maintain your spinal curvature.
