Tayco's J1 Task Chair is one of the best in its category. It simply sits well, with good upright support across the entire back, adjustable lumbar support and a synchro-tilt mechanism that encourages movement but also locks at your desired position. The J1 has a comfortable mesh upholstered flat seat with seat depth adjustment standard. The height adjustable arms come standard with arm pads that move front-to-back and side-to-side. When built with optional loop arms, the J1 makes an excellent conference / task chair for high traffic applications like car dealerships--simply a really good looking chair, with clean lines, breathable mesh back and a unique monochromatic aesthetic.
