The chair cushion can be filled with many substances, such as cotton, silk, rice husk, bamboo charcoal, magnetotherapy stone, mothballs, Chinese herbal medicines, etc. However, it is better to use Chinese herbal medicine to supplement it, which can not only keep warm, but also play a medicinal role. Semen Cassiae and Fructus Crataegi can be selected from Chinese herbal medicines.

Both cassia seed and hawthorn are beneficial to kidney eyesight and liver fire. Although it is not taken directly in the cushion, long-term contact has great benefits.
