Achieving good posture when sitting, especially in a chair designed to support it, often involves proper adjustment. A key step, as highlighted in DSE training videos, focuses on setting the correct seat height relative to your desk.
Proper adjustment of your chair's seat height is crucial for maintaining correct posture and preventing strain. The goal is to ensure your upper body is comfortably aligned with your workstation.
Adjusting Seat Height for Forearm Position
According to guidance on correct sitting posture, particularly in a work setting:
- Determine Desk Height: Note the height of your desk or work surface.
- Adjust Seat: Raise or lower your seat so that your forearms can rest horizontally on your desk.
- Check Shoulders and Elbows: While your forearms are resting horizontally on the desk, ensure your shoulders are relaxed. Your elbows should be at a comfortable angle (typically close to 90 degrees, though the provided text only mentions they should be 'at a' position while forearms are horizontal).
This specific adjustment ensures that you are not hunching over or reaching up, which can strain your shoulders, neck, and back.
- Incorrect Height (Too Low): You might have to reach up, straining your shoulders.
- Incorrect Height (Too High): You might have to hunch down, putting pressure on your lower back and potentially restricting leg movement.
By focusing on this seat height adjustment, you create a foundation for other aspects of good sitting posture, such as back support and foot placement.
