The Impact of Ergonomics

The risk of musculoskeletal disorders can be significantly reduced by ensuring that your chair is properly adjusted to conform to the body and the environment it’s being used in. 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:

Ergonomic recommendations

The BACKREST HEIGHT adjustments provide proper lumbar back support to promote good posture, supporting the natural inward curve of the lower back.

SEAT DEPTH should be adjusted so there’s at least 2 ½” in-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 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°.

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 chairs armrests so that the wrists are straight.
