Abstract (en)
A task chair (20) including seat support structure (26), a backrest frame (68, 112, 122, 150) attached to the seat support structure, and a backrest (72a, 72b, 72c, 72d, 72e) supported by the backrest frame. The backrest includes a back support surface (94a, 94b, 94c, 94d, 94e) which may ergonomically conform to a seated user when the user shifts positions while sitting in the chair. The back support surface includes rigid (80a, 80b, 80c, 80d, 80e) and flexible portions (90a, 90b, 90c, 90d, 90e) connected to one another, the flexible portions allowing resilient flexing of the back support surface to create conformance zones which dynamically support the back of a seated user in an ergonomic manner. <IMAGE>
