Seating unit with adjustable lumbar device

A seating unit comprising:

• a back support;
• a back cover located on a front surface of the back support but separable therefrom at least in a lumbar area of the back cover;
• and
• a lumbar device adjustably positioned between the back support and the back cover, the lumbar device including a longitudinally, non-stretchable flexible panel configured to slidingly engage the front surface of the back support and a rear surface of the back cover, respectively, and still further including handles that track along edges of the back support and yet still further including stretchable material that connects the handles to respective ends of the the flexible panel, whereby vertical movement of the lumbar device causes a shape change of the back cover for providing improved lumbar support to a seated user.

A seating unit comprising:

• a back support including side frame members and horizontally extending resilient members spaced in a vertical direction in a lumbar area of the back support;
• a back cover shaped to cover at least a front of the side frame members;
• and
• a lumbar device positioned between the back cover and the resilient members for affecting lumbar support, the lumbar device having a body with end sections connected by a middle section, upper and lower edges of the vertical end sections being relatively thin and defining a larger vertical dimension than the middle section forming wedges and shaped to guide the upper and lower edges of the middle section over the resilient members as the lumbar device is vertically adjusted.
