An Age-Old Solution for a More Comfortable Sleep Forget synthetic pillows. We've found a natural, better solution that's hypoallergenic, too. The tiny buckwheat hulls inside naturally contour to your head and neck giving you stable support. They won't go flat either, thanks to their pyramid-like shape causing them to interlock rather than compress. You can even adjust the firmness - unzip covering and remove some hulls for a softer pillow. No worries of heat build-up, unlike synthetic fillings (lets your head stay at a constant temperature all night). Hulls come from USA-grown buckwheat. Pillows are handmade in USA, too!. USA made in Ohio. A standard size pillow: 19" x 26". About 7 lb. Does NOT include a pillow case. Note: Other sizes also available.
