The stylish task chair includes a base with casters, a mounting plate, a seat frame, a back frame, a pair of springs and a seat and backrest. The frames are formed of steel wire of seven-sixteenth inch diameter. The chair is formed by welding the springs to the seat frame and the mounting plate and by welding the back frame to the mounting plate, the back frame being contiguous with the springs. A seat panel is fastened to the seat frame and a backrest panel is mounted to the back frame. Two horizontally disposed steel wires are welded to the back frame and support armrests. The spring allows the rearward portion of the seat to pivot and the cantilevered back frame allows the backrest to flex, these pivoting and flexing movements being independent of each other. The steel wire offers comfort and an airy open look. Seat and backrest cushions may be connected to the panels.
