II. Selection Tips

1. Appropriate Size:

• Seat Height: After adjustment, feet should naturally touch the ground to avoid poor blood circulation due to leg suspension;
• Seat Depth: There should be a 2-3 finger gap between the front edge of the seat and the back of the knee to prevent pressure on the sciatic nerve.

2. Chair Type Selection:

• Upright Sitting for Office Work: Prioritize attention to lumbar support strength, seat cushion softness and hardness, and armrest adjustability (e.g., height, angle);
• Reclining for Rest: Check the range of motion of the backrest (e.g., maximum recline angle) and the adjustment method of the chassis (e.g., gravity sensing or manual locking).

3. Material Preference:

• Mesh: Highly breathable, suitable for summer or individuals who sweat easily, but pay attention to the issue of elasticity degradation;
• Sponge: Significant differences in softness, hardness, and wrapping feel, requiring actual sitting to judge comfort.

4. Functional Adjustments:

• Weight Capacity: Should cover the user's weight to avoid structural damage from long-term overweight;
• Adjustable Functions: Such as headrest height, lumbar support position, armrest extension, etc., should be selected based on needs;
• Installation and After-sales Service: Confirm the completeness of accessories, installation difficulty, and warranty period (e.g., 5 years for the frame, 1 year for the mesh).
