II. Key Considerations for Purchase

1. Support

   • Lumbar Support: Should fit the L1-L5 lumbar segments, avoiding suspension or excessive pressure, with preference for adjustable height/depth designs.
   • Backrest: Should provide wrap-around support from the shoulders to the sacrum, reducing the risk of spinal scoliosis.
   • Seat Cushion: Pay attention to softness (e.g., latex/foam), support (e.g., zoned support), and breathability (e.g., mesh fabric), with adjustable seat depth to fit different leg lengths.

2. Adjustability

   • Armrests: Support vertical, forward/backward, and rotational adjustments to fit various scenarios like keyboard operation and reading.
   • Headrest: Adjustable in height and angle to support the cervical spine and prevent forward leaning.
   • Base: Prefer products with recline locking and gravity-sensing adjustment to enhance午休 (noon break) comfort.

3. Material and Structure

   • Base: Should be stable and anti-tip, preferably made of steel or high-strength plastic.
   • Gas Lift: Look for TUV/SGS certification to avoid explosion risks.
   • Frame: Nylon + glass fiber or steel frames are more durable, avoiding plastic part aging and breakage.

III. Tips to Avoid Pitfalls

1. Avoid 'Heavy Lumbar, Light Seat': Insufficient buttock support can lead to pelvic retroversion and lumbar muscle strain, ensuring the front of the seat cushion does not compress the thighs.
2. Be Cautious with 'Fixed Foam Seat Cushions': Some high-end chairs have non-adjustable seat cushion lengths, which may not be friendly to users over 180cm tall or with long legs.
3. Beware of 'Ordinary Mesh Chairs': With fixed support, lighter individuals may feel too hard, while heavier individuals may cause mesh sagging and uneven pressure distribution.
