A seating system has a tiltable seat coupled to a base, which can be coupled to a motor vehicle or other device. The seat includes a seat bracket coupled to the base by a seat tilt pivot. The seat is configured to maintain a user's body in a fixed position during tilting throughout the seat's range of tilt angles. A seat adjustment mechanism allows angular adjustment of the seat and locks the seat at a fixed tilt angle relative to the base. The seat tilt pivot axis is located approximately vertically below the center of gravity of a loaded seat, thus reducing the force needed to tilt a loaded seat. By fixing or maintaining the seat tilt pivot vertically beneath the load being pivoted, the amount of force needed to control seat tilting can be limited to forces that a typical user can exert with one or two hands.
