II. Key Points for Selection

1. Size Fit

   • Seat Height: Ensure feet rest naturally on the ground, avoiding suspension or tiptoeing.
   • Seat Depth: Maintain a 2-3 finger gap between the back of the knee and the edge of the seat cushion to prevent compression of leg blood vessels.
   • Backrest and Headrest: Those with greater height should pay attention to the adjustment range to ensure neck and head support.

2. Chair Type Selection

   • Sitting Upright for Work: Prioritize chairs with adjustable lumbar support, no pressure at the front of the seat cushion, and armrests that support the elbows.
   • Reclining for Rest: Pay attention to the backrest tilt angle (recommended 110°-135°), chassis stability, and footrest functionality.

3. Material Preferences

   • Mesh Material: Highly breathable, suitable for summer or those who sweat easily, but note the load-bearing capacity.
   • Sponge Seat Cushion: Optional softness and hardness, strong wrapping sensation, but requires regular cleaning to prevent sagging.

4. Function Verification

   • Load-Bearing Range: Ensure the chair's maximum load-bearing capacity is ≥ 1.2 times the user's weight.
   • Adjustment Functions: Include seat height, armrests, lumbar support, headrest, etc., and test the smoothness of adjustments in practice.
   • After-Sales Terms: Pay attention to the warranty period (recommended ≥ 3 years) and return and exchange policies to reduce usage risks.
