A hospital bed includes a bed portion, a frame supporting the bed portion, and a seating system connected to the frame and including a seat component. The seating system is moveable between a stored state in which the seat component is at least parrtially located within an expanse of the frame, and a seating position in which the seat component is spaced apart from the frame for seating on the seat component. The seating system may include a rotating joint and a lateral bar that extends from the joint to a seat support so the seat component can be rotated away from the frame, in either a single pivot configuration, or double pivot configuration with multiple lateral bar segments and rotating joints. The seating system may include a flip seat design in which a seat component is moved out of the stored state and rotated to the seating position.
