How to Inspect Office Chairs

Inspecting office chairs requires a comprehensive examination from multiple aspects, including materials, specific items for second-hand chairs, chair types, and other defects.

Material and Physical Performance Inspection:

• Sensory Identification: Genuine leather feels soft and delicate with good breathability; the leather texture is natural, without mildew spots, cracks, or peeling.
• Fabric Defects: Check for color differences, fading, holes, pilling, yarn slippage, and edge wear; for leather, ensure there are no glue marks, burn marks, or cutting imprints.
• Metal Components: Ensure there are no burrs, deformations, or sand holes, with smooth edge sealing to avoid sharp edges.
• Plastic Components: Check for cracking, deformation, or insufficient filling; pay special attention to armrest burrs and flow marks.

Specific Inspection for Second-Hand Ergonomic Chairs:

• Gas Lift Certification: Confirm that the gas cylinder has SGS, BIFMA, or TÜV certification stamps; lack of identification or blurred identification may pose a risk of explosion.
• Mesh and Seat Cushion: Check for mesh sagging, breakage, or fading, and seat cushion foam collapse or slow rebound; press the seat cushion for 3 seconds and observe the rebound.
• Chassis Noise: Listen for creaking or air leakage sounds during lifting or tilting; test stability by lifting continuously 10 times.
• Armrest Wear: Confirm that the leather/paint surface is not peeling, and the armrests are not loose or difficult to lock; abnormal wear may indicate refurbishment.
• Signs of Refurbishment: Check for paint touch-up color differences, stickers covering screws, or non-original parts; smell for any pungent new paint odor.

Inspection by Chair Type:

• Type I (Tiltable Chairs): Test whether functions such as synchronous tilting and central tilting work properly.
• Type II (Fixed Seat Angle Chairs): Confirm that the backrest tilt angle is fixed without looseness.
• Type III (Fixed Seat Angle and Backrest Chairs): Check the stability of the chair legs or sled base, ensuring no structural cracking.

Other Defect Inspections:

• Sales Packaging: Ensure the packaging is not damaged, wet, or has incorrect information, with all accessories present and well-protected.
• Labels and Printing: Check for missing, incorrect, or blurred instructions, hangtags, or labels, ensuring accurate labeling information.
• Appearance Defects: Confirm there are no sharp fragments, burrs, or pointed edges, with no structural cracking, exposed metal, or fabric with diagonal or bowed weaves.
• Assembly Issues: Ensure parts match correctly, hardware gaps are reasonable, and there are no loose or missing components.
• Function Testing: The tilting function should be adjustable, and the gap between the chair feet and the ground after pressing the seat should not exceed 5mm.
