Abstract
A seating unit is provided having a base, a back frame pivoted to the base for movement between upright and reclined positions, and a seat slidably supported on the base assembly and pivoted to the back frame so that the seat moves forwardly and its rear moves forwardly and downwardly with the back frame upon recline. A flexible back shell is connected to the back frame at top and bottom locations for controlled flexure when a seated user reclines and/or flexes his/her back, and is provided with lumbar adjustment for improved lumbar force/support and shape.
