Ergonomics is the science of fitting your workspace for the comfort and health of your body. Because each body is different, the best ergonomic chair height for your co-worker might not be the right fit for you.
Determining the right chair height for you comes down to your height, body type, and work style. For example, if you like to recline in your computer chair while reviewing documents, you’ll want a chair with an adjustable reclining feature. And, of course, people of different heights will need different height chairs for comfort.
Even if your chair doesn’t have numerous adjustment points, most are still height adjustable. Many people can adjust a standard office chair to the proper seat height with minimal (if any) modifications. As a rule, you want the seat height to sit just below your kneecap.
Here’s how to take your measurement:
- Sit on a chair that allows your legs to bend at or near a 90-degree angle with your feet flat on the floor.
- Use a measuring tape to measure the distance from the floor underneath your heel straight up to the bottom of your kneecap. Record this measurement.
- Double-check your measurement while standing, or ask a friend to help you.
This measurement is the best ergonomic chair height for your body — use it to adjust your seat cushion properly. When you sit in a chair adjusted to the correct height, your weight should feel evenly distributed on the cushion with your feet firmly on the floor. If you feel pressure near the front of the chair behind your knees, you may need to lower the seat height.
