Office Chair Placement Tips

The proper placement of office chairs requires a combination of ergonomics and space planning. Here are specific tips:

1. Matching the Height and Angle of the Desk and Chair
It is recommended to keep the height of the office desk between 72-76 centimeters, and adjust the backrest angle of the chair to 110-135 degrees. This angle range can disperse lumbar pressure and prevent lower back fatigue caused by prolonged sitting. If the chair supports a recline-lock function, it can further reduce the risk of spinal lordosis.

2. Reserving Aisles in General Employee Areas
The placement of chairs should ensure that the aisle width is at least 1.2 meters, which can prevent people from kicking power cords or table corners when walking and facilitate emergency evacuation. If space is limited, prioritize ensuring the width of the main aisles and appropriately compress secondary areas to 1 meter, but avoid cluttering.

3. Staff Spacing Standards in Office Areas
For single-person workstations, it is recommended to have a chair spacing of 1.5 meters and adopt a 'honeycomb' arrangement (i.e., hexagonal layout). This layout can maximize space utilization while ensuring independent operating areas for each person and reducing interference caused by physical collisions. For open office areas, space can be further divided using low partitions or green plants.

4. Dynamic Adjustment of Desk-Chair Spacing

• Daily Office Work: Maintain a spacing of 60-75 centimeters between the chair and the desk to ensure that the arms hang naturally with the elbows at a 90-degree angle and the back remains straight without leaning forward.
• Meeting Discussions: Increase the spacing to 80 centimeters to provide space for leg stretching and document placement, while avoiding leaning forward during communication due to the chairs being too close.

5. Detail Optimization to Enhance Comfort

• Inward Adjustment of the Chair Front: Adjust the front of the chair inward by 2-4 centimeters to allow the soles of the feet to fully touch the ground and prevent poor blood circulation in the legs due to suspension.
• Posture Calibration: Keep the chest 3-5 centimeters away from the edge of the desk and position the chair 5-10 centimeters inward from the desk to ensure that the waist is tightly against the backrest and reduce the risk of spinal scoliosis. If the chair does not have a lumbar support, a towel or cushion can be placed between the backrest and the waist.

Precautions:

• Regularly check the stability of components such as the chair's gas lift and casters to prevent accidental falls due to malfunctions.
• If using a height-adjustable desk, synchronously adjust the chair height to keep the 'elbow-keyboard-desktop' in a horizontal line.
• It is recommended that people who work at a desk for long periods stand up and move around every 30 minutes. Combining this with optimized chair placement can further reduce the risk of occupational diseases.
