1, comfort and adjustability: Buckwheat pillow is filled with buckwheat shells, which has the characteristics of high softness and adjustable height. It can be adjusted according to personal needs and head shape, providing more suitable support and making people sleep more practically. The millet pillow is made of millet or filler, and its softness and adjustability are relatively poor. In contrast, buckwheat pillow is better than millet pillow in comfort and adjustability.

2. Cervical support and breathability: The filler of buckwheat pillow can provide enough support to maintain the normal physiological curvature of cervical spine and avoid excessive collapse of neck. Buckwheat pillow has good air permeability, which can dissipate the excess heat generated by the head and neck in time, which is beneficial to the rest and relaxation of the head and neck tissues. However, millet pillow does not have enough support. In contrast, buckwheat pillow performs better in cervical spine support and breathability than millet canned pillow.
