A compliant back for a seating unit includes a rigid upright defining a track, and a flexible back shell configured to support a seated user's upper body, including a top pivot pivotally connected to a top section of the back shell and a pivot/slide member slidably connected to the track of the back shell. A biasing device is operably coupled to the pivot/slide member that biases the pivot/slide member toward a position where the flexible back shell protrudes forwardly to a shape chosen to optimally support a seated user.
