<p>A chair for supporting the human body, and for adjusting to meet the unique ergonomic characteristics of individuals is characterized by a base (32, 38) having a pair of front upwardly and rearwardly extending front terminal sections (33, 39) on which a back support member (23, 118, 119) is adjustably mounted for movement between various intermediate vertical positions. The base has a pair of upwardly and forwardly extending rear terminal sections (34, 40) on which a seat member (22) is adjustably mounted between different vertical heights. Different relative positions of the seat member and the back support member not only vary the relative vertical height of these members above the base, but also change the seating area on the seat member for the different adjustment positions of both the seat member and the back support member.</p> |
