Moreover, most of the conventional bed devices as described above only raise the upper half of the body, and therefore, when the caregiver stands up, the caregiver stands on the knees of the sleeping person or removes the legs from the bedside. There is a problem that it is difficult to perform the movement by itself because it is necessary to assist the wearer to attach the back to the floor. In addition, in the case of an action in which the upper body is kept upright for a long time, such as reading or eating, the load on the legs and waist may be unstable and the sitting posture may not be stable, which may be inconvenient.

Therefore, if there is a bed which has a simple structure and can surely wear the soles of the feet on the floor surface by itself, it becomes easy to perform the rising motion. Further, in the case of a posture of raising the upper half of the body, if a posture of sitting on the body is possible, the posture can be kept stable for a long time, and the caregiver's labor can be significantly reduced. Moreover, it is very useful for rehabilitation at home and communication with family.
