A buckwheat pillow is a type of pillow filled with the hulls of buckwheat, a grain-like seed. These hulls provide firm support and can be adjusted to suit individual comfort preferences. The natural material allows for good airflow, helping to regulate temperature during sleep. Unlike traditional pillows, buckwheat pillows conform to the shape of the head and neck, promoting proper spinal alignment. They are often considered a more eco-friendly option, as the hulls are a byproduct of the buckwheat milling process. Many people find them beneficial for reducing neck and back pain.
