II. Key Points for Selecting an Ergonomic Office Chair

1. Lumbar and Back Support Fit Prioritize models with lumbar support that can be adjusted up and down, as well as forward and backward, ensuring a snug fit against the lumbar curve in various sitting positions (e.g., upright or reclined) to prevent fatigue caused by suspension.

2. Seat Cushion and Size Compatibility The seat cushion should have moderate hardness to avoid excessive sinking of the buttocks or pressure caused by excessive hardness. Additionally, select the seat width, depth, and height based on height: the seat width should exceed the hip width by 5-10 cm; the seat depth should allow the thighs to fully conform without pressure on the back of the knees; and the seat height should enable the feet to rest flat on the ground with the thighs parallel to the ground.

3. Practicality of Adjustment Functions Focus on the ease of adjusting core functions, such as seat height, lumbar support, armrests, and recline angle. Avoid models with complex operations or limited adjustment ranges, and prioritize testing the smoothness of actual use.

4. Structural Stability Check for smooth operation of the gas lift and stability of the base when reclining, and confirm that the product has passed safety certifications such as BIFMA to ensure no risk of tipping over during long-term use.
