About Buckwheat Hull Filling
Buckwheat hulls are a natural filling material known for their breathable structure. Air can move freely between the hulls, helping to maintain a comfortable sleeping environment.
This filling is typically firmer than foam and may produce a slight sound when the pillow is moved. The filling can be adjusted by removing some hulls to suit your preferred level of support.
Pillow Size
23 × 15 × 9.5 cm (approximate dimensions).
