Setting up a computer workstation ergonomically is essential for maintaining comfort, reducing the risk of injury, and increasing productivity. Here’s a comprehensive guide to achieving the proper ergonomic setup:

1. Chair

• Height: Adjust the chair height so that your feet are flat on the floor or on a footrest, and your knees are at a 90-degree angle.
• Back Support: Ensure the chair provides adequate lumbar support to maintain the natural curve of your spine.
• Seat Depth: There should be a small gap (2-4 inches) between the edge of the seat and the back of your knees.
• Armrests: Adjust the armrests so your shoulders are relaxed, and your elbows are at a 90-degree angle with your forearms parallel to the floor.

2. Desk

• Height: The desk should be at a height where your elbows are at a 90-degree angle when typing, with your forearms parallel to the floor.
• Legroom: Ensure there is enough space under the desk for your legs to move freely.

3. Monitor

• Height: The top of the screen should be at or slightly below eye level.
• Distance: The monitor should be about an arm’s length away (20-30 inches).
• Angle: Tilt the monitor slightly upward (10-20 degrees) to reduce neck strain.
• Alignment: Center the monitor directly in front of you to avoid twisting your neck.

4. Keyboard and Mouse

• Position: Place the keyboard and mouse close together and at the same height to avoid reaching.
• Height: Your wrists should be in a neutral position, not bent up or down.
• Support: Consider using a wrist rest to maintain neutral wrist posture.

5. Desk Accessories

• Document Holder: Use a document holder placed at the same height and distance as your monitor to minimize head and neck movement.
• Phone: Place your phone within easy reach to avoid overreaching.

6. Footrest

• Usage: If your feet don’t rest flat on the floor, use a footrest to support your feet and maintain proper leg positioning.

7. Lighting

• Position: Position lighting to avoid glare on the monitor. Use adjustable desk lamps if necessary.
• Brightness: Ensure sufficient lighting to reduce eye strain, but avoid direct light on the screen.

8. Breaks and Movement

• Regular Breaks: Follow the 20-20-20 rule: every 20 minutes, look at something 20 feet away for at least 20 seconds.
• Movement: Take short breaks to stand, stretch, and move around to reduce muscle fatigue and improve circulation.
