Automobile four-season mats can be divided into ordinary and health-care types according to their functions. Health-care type refers to those four-season summer sleeping mats with health-care Chinese herbal medicine or massage function.

The classification of automobile four-season mats is not as obvious as that of automobile seat covers and automobile cushions. We generally classify them according to fillers, including cassia seed, buckwheat shell, tourmaline and so on. For more information, you can go to official website, the Seven Heroes.
