Ergonomic task chair for office workers

The BOSS B317-BK is a black fabric office chair built for daily desk work. It offers a thick padded seat with a waterfall edge and a cushioned backrest that includes built-in lumbar support. Fixed loop arms provide a stable resting position for the forearms. The chair is designed for users who want adjustable posture settings without complex mechanisms.

Height and depth adjustment only

Seat height is controlled by a pneumatic gas lift for quick changes. The backrest depth can be adjusted to suit different torso lengths. There is no tilt tension control, knee tilt, infinite lock or upright lock function. The back angle itself is not adjustable independently of the seat. The five-star nylon base measures 25 inches in diameter and carries hooded dual-wheel casters for mobility.

Fixed loop arms cannot be repositioned

Armrests are moulded into a continuous loop and cannot be raised, lowered, pivoted or slid. Buyers who need adjustable arm support for varied tasks or shared workstations should look elsewhere. The chair delivers core ergonomic tuning through seat height and back depth alone.
