How to Adjust an Ergonomic Chair
Sitting for long hours at a computer can be wearing on your back, neck and legs, so it's important to sit in an ergonomic chair that offers support and comfort and that you can adjust to your body type and height. Not only can an adjustable ergonomic chair increase your productivity but it also can help keep fatigue away.

1
Study the adjustable controls on your ergonomic chair. You should be able to change the height of the seat and armrests, get the best support you can for your back and tilt and swivel the chair to meet your preference. Get familiar with where the controls are and how to reach them. Experiment with what feels best for your body height and size.

2
Stand in front of the chair to adjust its height. The seat should be just below your knees at its highest horizontal position. This will allow you to place your feet flat on the floor when seated.

Sit in the chair and check for proper positioning according to your height. You should be able to fit a clenched fist in the area between your calves and the front edge of the seat. If your knees are too close to the edge of the seat, use the seat back adjustment control to move it forward or backward until the seat back is in the proper position for your height.

Use the back rest tilt control to move it forward, backward, up or down until it fits against the curve on your lower back and feels comfortably firm and supportive. Correct back rest adjustment is important to maintaining good posture and relaxation during long hours at your desk.

5
Measure proper armrest height by bending your elbows and placing them on the armrests so that they barely touch. This adjustment will help keep your posture intact and your shoulders and upper back from becoming fatigued.

Tips & Warnings
Read your user's manual and get familiar with the controls on your ergonomic chair.
Your ergonomic chair should have controls that are easy to adjust while you're sitting.
Place your feet on a footrest if you can't place them flat on the floor.
Be sure that your legs have sufficient room to move under your desk.
Choose an ergonomic chair with armrests that are less than 10 inches high. You'll be able to move your chair closer to your work station without the armrests bumping against it.
Elbows that are improperly elevated on an armrest can cause upper back and shoulder discomfort.
A chair with no adjustable controls offers no support or health benefits.
