However, this patent document 2 also provides a ventilation function only by means of the groove portion, and therefore, although the disadvantage of patent document 1 is somewhat improved, it does not provide an effective ventilation solution.

And, because the seat board is made of hard material, therefore, the shortcoming that is hard to sit for a long time still exists, and in order to solve this problem, after inserting various elastic materials to the surface of the seat board, use leather or cloth to In the case of covering, the shortcoming that the ventilation function of sweat and other secretions is hindered due to the inability to ventilate between the buttocks and the seat board still exists, and when a person sits, the buttocks are caused by the friction between the hip bone and the seat board surface. Pain or stiffness, inconvenience in use and hygiene problems caused thereby still exist.
