The invention provide the seating apparatus to be used on the chair of the horizontal sitting base plate in order to avoid the lower back pain. By sitting on the seating base plate tilted forward from 5 to 45 degree, the person can keep the angle between the spine and the thigh from 95 to 135 degree. As the seating apparatus is equipped with the knee front holder connected with the supporting part, which is connected with the seating base plate by the half fixed joint at an another end of the supporting part, the slip down of the body on the seating base plate is stopped by the knee front holder and the steady sitting is available.
