An ergonomic device (10, 110) for a vehicle seat includes a pressure surface (106, 206) oriented toward a seat cushion so that the pressure surface deploys to support a seat occupant. A mount bracket (102,202) fixes the device to a frame of the automobile seat. A linkage (112, 144, 166) between the pressure surface and said mount bracket allows the pressure surface to be selectively positionable between a first position disposed to extend for support of a seat occupant and a second position that is retracted. A power actuator (20, 130) is in operative communication with the linkage such that the power actuator mediates travel of the pressure surface between the first and second positions. The power actuator (20, 130) is in communication with a use anticipation indicator (40) such that the power actuator is engaged to place the pressure surface in the second, retracted position upon a signal from the use anticipation indicator.
