ABSTRACT:
A seating unit includes a back support with a perimeter frame defining an opening, and a plurality of resilient members spanning the opening. An upholstery cover extends over and covers the resilient members and a front of the perimeter frame. A bow-tie-shaped lumbar device is positioned between the cover and sides of the perimeter frame for vertical adjustment. The lumbar device includes a body with end sections defining a greater dimension than a middle of the body. Upper and lower edges of the end sections are thin and serve to wedgingly slip between the cover and the resilient members in a manner leading the middle over irregular surfaces between the resilient members. A thick area between the upper and lower edges causes a change in lumbar support force and shape as the lumbar device is adjusted. Handles are attached to the body by stretchable fabric.
