An ergonomic chair (10) includes a four-bag linkage arrangement wherein a lower frame member (100) is provided with a rigid front support (130) and a rigid rear support (120) with a seat member (30) pivotably connected to the front support (130). A back rest (20, 200) has an upper support pivotably connected at an upper end of the rear support (120) of the lower frame. A link member pivotably connects at a first end to a rear support (120) of the seat member and at second end to a lower support of the back rest. This novel arrangement permits tilting movement of the backrest rearwardly relative to the lower frame member causing elevation of a rear portion of the seat member, permitting the feet to remain on the floor and alleviating pressure on the user's thighs, while rotation occurs closely coincident with the pivot axis of the user's hips ad while maintaining a generally uniform gaze line.
