PROBLEM TO BE SOLVED: To provide a movable bed system capable of shifting a body position of a care-receiver or the like to a side-lying lateral position safely and calmly without disturbing a sound sleep of the care-receiver regardless of the lying position.SOLUTION: A movable bed 1 includes bed bottoms 4a and 4b divided into right and left. In the bed bottoms 4a and 4b, a bottom outside part is rocked vertically by a bottom drive part 3 having electric linear actuators 2a and 2b, and link mechanisms 6a and 6b with a center part side as a fulcrum. In the movable bed 1, one of the right and left bed bottoms 4a and 4b is operated upward with an angle larger than that of the other one at a predetermined time interval. At this time, the operation of the linear actuators 2a and 2b is controlled so that an inclination angle of the bed bottoms 4a and 4b on the side with small initial operation amperage is larger than that of the bed bottom 4a and 4b on the side with large initial operation amperage. Thereby, a body position of a user on the bed is shifted to a side-lying lateral position or a supine position while preventing the fall of the user.SELECTED DRAWING: Figure 2
