 However, in the above chair, when a person having an affected area such as hemorrhoids in the buttocks sits down, the affected area comes into direct contact with the seated area, so that the seat cannot be comfortably seated.

Therefore, a recess is formed in a part of the seat, and the affected part of the buttocks of the person seated in the recess is faced to the seat so that the affected part is not in direct contact with the seat. It is possible to prevent it. However, as described above, even if a recess is formed in a part of the seat and the affected part of the buttocks is placed to face the recessed part, the position of the affected part and the size of the seated person can be considered. In some cases, the affected part cannot be opposed to the recessed part and cannot be comfortably used by all persons. In addition, since the above-mentioned chair has a back portion that can be directly angled with respect to the seat portion, when sitting on the seat portion while leaning the back against the back portion, the back portion of If the angle is adjusted, the angle of the back leaning against the back can be adjusted arbitrarily, but as described above, even if the angle of the back with respect to the seat is adjusted, the user can still sit on this seat. Since the positional relationship between the buttocks of a person and the recesses provided in the seat does not change, it is possible to sit with the affected areas facing the recesses depending on the position of the affected area on the buttocks and the body shape of the person to be seated. Therefore, the affected part cannot be used properly because it directly contacts the seat.

The object of the present invention is to ensure that the affected area can be made to face the concave portion provided in the seat portion regardless of the body shape of the seated person and the position of the affected area in the buttocks, and the affected area can be directly attached to the seat portion. The aim is to provide a sitting chair that is comfortable for everyone to use without contact.
