Adjusting Your Chair to Your Body
The risk of musculoskeletal disorders can be significantly reduced by ensuring that your chair is properly adjusted to conform to your body and environment. Evaluate features such as seat size and depth, back height, arm height, chair height, and seat/backrest tilt to properly select and adjust your chair.
Chair Adjustments
Backrest Height
Backrest slides up and down and locks in place to ensure proper lumbar adjustment.
Seat Depth
Backrest slides in and out, on non-tilt models, to provide an easy adjustment to create additional room between the seat cushion and the backrest.
Seat Height Range
Chair can be raised or lowered to numerous height ranges varying between desk, mid & tall height.
Chair Tilt
Chairs have either no tilt options or a variety of tilt control options to properly position the chair for maximum comfort and ergonomic functionality:
NON-TILT
NO Seat or Backrest Tilt – 1 lever
1 lever to adjust seat height.
Manual backrest height and depth adjustment.
TILT
Articulating Seat and Backrest Tilt – 2 levers
1 lever to adjust the angle of the seat and backrest simultaneously.
1 lever to adjust the seat height.
Manual backrest height adjustment.
DELUXE TILT
Independent Seat and Backrest Tilt – 3 levers
1 lever to adjust the angle of the seat.
1 lever to adjust the angle of the backrest.
1 lever to adjust the seat height.

Ergonomic Recommendations
The BACKREST HEIGHT adjustments provide proper lumbar back support to promote correct posture, supporting the natural inward curve of the lower back.
SEAT DEPTH should be adjusted so that there’s at least 2.5” between the edge of the chair’s seat pad and the back of the knee. Adequate seat depth allows the user to use the lower portion of the backrest without creating pressure on the back of the knees.
SEAT HEIGHT should be adjusted so that feet are flat on the floor or footring with the upper legs angled slightly downward to improve lower body circulation. The torso-to-thigh angle should not be less than 90 degrees.
Adjust the CHAIR TILT of the chair to a reclined posture of 100 degrees to 110 degrees. The neck and shoulders should be relaxed. The lower arms should be +/-90 degree angles, preferably resting on the chair’s armrests so that the wrists are straight.
