I've been experiencing headaches and neck pain overnight so a good deal of disturbed sleep. Even though I've returned to using an orthopaedic pillow - it didn't help very much. I receive Panda's newsletters and read about the Hybrid pillow. Without the promise of a 30 day free trial I probably wouldn't have bought one as they are rather expensive. I'm so glad I did. The pillow looks good feels good and I've experienced a full two weeks of pain free sleeping - so far! A price well worth paying for.
