SPECTRUM ADJUSTMENT INSTRUCTIONS
We recommend computer users adopt an open-angle sitting position, with knees slightly lower than hips.
Always sit near the back of your seat.
Adjust your backrest height so that the lumbar support fits into the lumbar contour of your back.
Adjust your backrest angle, seat height, and seat angle (on a 3-lever chair) to a position that allows you to sit close to your workstation.
Your feet should be flat on the floor or on a footrest. There should be no pressure under your thighs.
Keyboarding and mouse operation should be achieved comfortably without stretching.
