Considerations for Office Chairs

The considerations for office chairs mainly lie in two aspects: Feng Shui and dimensions. Reasonable selection and placement can enhance work efficiency and comfort.

Feng Shui Considerations

1. Position Selection

   • Avoid sitting with your back to the door: Sitting with your back to the door exposes you to cold drafts, causing subconscious tension, leading to disorganized thoughts and poor decision-making. The solution is to adjust the position of your desk and choose a chair with a backrest.
   • Avoid sitting with a window behind you: Having no support behind you can lead to a lack of security. This can be resolved by adjusting the position of your desk or choosing a high-backed chair.
   • Back against the wall: Symbolizes having support, implying assistance from influential people; facing a well-lit area symbolizes a hopeful future.
   • Avoid sitting directly facing the door or in a corner: Sitting facing the door can make you feel unstable and susceptible to external disturbances; sitting in a corner is not conducive to interpersonal communication. Choose an open position instead.

2. Other Dos and Don'ts

   • Position for business owners: Choose a location with smooth traffic flow and gathering of energy. The desk should be placed in a position with a window on the 'left dragon' side, but the window should not be too large.
   • Avoid sitting near walkways or windows: Prone to disturbances and lack of privacy; avoid sitting under a crossbeam, which can create a sense of oppression and affect health.

Dimension Considerations

1. Standard Dimensions

   • Seat height: The most scientific range is 40-45 centimeters, ensuring that your knees are at a 90-degree angle when your feet are flat on the ground, avoiding leg suspension or pressure.
   • Seat depth: 38-42 centimeters is ideal. Too short causes your thighs to hang, while too long presses against the back of your knees, affecting blood circulation.
   • Backrest height: At least 40 centimeters to firmly support your waist and reduce fatigue from prolonged sitting.
   • Armrest height: 20-25 centimeters to allow your shoulders to hang naturally, avoiding arm suspension or elevation.

2. Chair Selection by Position

   • Boss's chair: Can be up to 75 centimeters high with a wide seat surface, projecting authority while ensuring comfort.
   • Employee's chair: The basic model should focus on ergonomics, such as adjustable seat depth. For shorter individuals, choose a seat height of ≤42 centimeters; for heavier individuals, choose a sturdy mesh material for enhanced support.

3. Matching Tips

   • Desk-chair height matching: When the standard desk height is 78 centimeters, adjust the chair to 48 centimeters for optimal comfort; prioritize chairs with adjustable features (such as 5 centimeters of seat depth sliding and multi-directional armrest rotation).
   • Material selection: Breathable mesh is superior to leather, as it is less prone to sweating in summer; ensure the gas lift is certified with 5GS for safety.
