A Cooling Buckwheat Pillow for Hot Sleepers Who Still Want Firm Support The Buckwheat Pillow – Cooling Edition is made for sleepers who want the firm, adjustable support of buckwheat hulls with a cooler surface feel. It combines a cool-to-the-touch outer cover with a breathable buckwheat hull core, helping heat move away from the pillow surface without foam, gels, or electricity. Is This Pillow Right for You? If you sleep hot or live in a warm climate: The Cool-Touch cover is designed for a cooler surface feel compared with a traditional cotton pillowcase. If you want firm buckwheat support: The hull core molds around your head and neck while staying steady through the night. If you want a ready-to-use setup: The removable outer cover is already included, so you do not need to buy a separate pillowcase. How the Cooling Edition Works The Cover: Cool-Touch Star Constellation Fabric Feels cool against the skin for sleepers who prefer a fresher pillow surface. Finished with the PineTales star constellation design for a clean, modern look. Removable and machine washable for simple care. The Filling: 100% Organic Buckwheat Hulls The natural 3D shape of buckwheat hulls creates open space inside the pillow for steady airflow. Unlike foam pillows that can trap heat, buckwheat hulls allow air to move through the fill. Our hulls are 4-stage cleaned using screening, washing, heat treatment, and UV sterilization. Firm Support & Adjustable Loft Steady Neck Support The hull core holds its shape better than soft fiber or foam fill. Designed for side and back sleepers who prefer a firmer, more stable pillow feel. Adjust the Loft to Fit Your Sleep Position Both the inner case and outer cover include durable YKK zippers. Add or remove hulls to adjust the pillow height to your preferred sleeping position. Each pillow is intentionally overfilled, so you can remove extra hulls and keep them for later adjustments. Sizes, Care & Extras Sizes: Available in Japanese Plus 14" × 20", approx. 6.5 lbs, and Standard 20" × 26", approx. 13 lbs. Simple Care: Remove the hulls before washing. Machine wash the outer cover and inner case, then let both dry fully before refilling. Natural Fill: Filled with organic buckwheat hulls for breathable, firm, shapeable support. For side sleepers: Pair with our knee pillow for leg and hip alignment. Prefer the classic Sobakawa feel?
