Relax, unwind, and let go of the day's tension with the hypoallergenic buckwheat hull in the Tranquil Sleep Classic Pillow.  The classic pillow provides contoured support to your head and neck, encouraging muscles to relax and release tension throughout the night.  Inside the pillow, the buckwheat hull moves freely, conforming to your body's shape and position.  Better yet, buckwheat hull doesn't compress so your neck never gets strained and the natural properties allow air to circulate so your pillow stays warm in the winter and cool in the summer.
