Abstract

A back for an office chair comprises a peripheral frame shaped generally to outline the back of an occupant in the chair; a lumbar base structure attached to the frame; and a lumbar back support for an occupant of the chair connected to the lumbar base structure and extending toward the lumbar area of an occupant through an adjustable connection. The adjustable connection helps to provide comfort to the occupant and comprises one or more of a detent to allow adjustment of the height of the back support in relation to the frame, a movable joint to allow rotary motion of the lumbar back support in relation to movement of the back of the occupant, and an extensible connection to allow adjustment of the distance between the lumbar base structure and the lumbar back support. The chair back may also comprise at least one movable and flexible LED light supported by the back for reading comfort and may contain electrical circuitry to supply power to the LED light. The light may be removable with an electrical plug-in connection.
