Buckwheat hulls are the husks that protect the buckwheat kernel. The buckwheat used in pillows is organically grown in the United States, using no fertilizers or pesticides. To create the perfect organic buckwheat hull pillow, buckwheat hulls are surrounded by wool and then covered in a 100% organic cotton cover. Due to their nature, buckwheat hulls conform to contours of the head and neck, while Pure Grow Wool creates a cushioned sleeping surface.
