Abstract
To provide a bed apparatus that permits the bed to be tilted only when the knee bottom in the bed apparatus is raised so as to be able to positively prevent the user from slipping to the foot side when the bed is tilted. The bed apparatus includes: a tilting driver that can perform a tilting operation of the upper frame so as to create difference in height between the head side and the foot side and, at least, lower the foot side; and, an operational state detector that detects that a knee bottom actuation assembly for raising and lowering the knee bottom is operable. The tilting driver performs the tilting operation when the knee bottom forms an angle of 0 degrees or greater relative to the ground and when the operational state detector has detected that the knee bottom actuation assembly is operable.
