What to Inspect When Checking Office Chairs

When inspecting office chairs, it is essential to focus on appearance, dimensions and specifications, structural stability, material and workmanship, functionality and operation, safety, labeling and packaging, as well as other aspects. Details are as follows:

1. Appearance Inspection
   Verify that the overall color matches the order and that pattern printing or embroidery is clear and properly aligned. Check that surface finishes (such as painting, electroplating, fabric covering) are uniform, without runs, blisters, or color variations. Look for scratches, cracks, dents, as well as fabric threads, breaks, or stains. Ensure that metal parts are adequately rust-proofed and that plastic components are free from deformation or burrs.

2. Dimensions and Specifications Inspection
   Use professional measuring tools to check key dimensions such as seat height, seat width, seat depth, back height, armrest height, and spacing, ensuring they meet tolerance ranges (±2-5mm). Verify the overall proportional harmony, such as whether the angle between the backrest and seat surface conforms to ergonomic standards (95°-105°). Check that the travel ranges of adjustable components (such as gas lifts, headrests, and armrests) meet specifications.

3. Structural and Stability Inspection
   Visually inspect or tap the frame material (metal, solid wood, engineering plastics) for cracks, decay, or deformation. Confirm that screws, rivets, and welds are secure without looseness, that metal parts are free from rust, and that plastic connectors are not brittle. Apply vertical pressure to the seat (simulating a load of over 100kg) and observe for any wobbling or unusual noises. When testing the tilt function, check the reliability of the locking mechanism and the smoothness of the rebound. For swivel chairs, verify the flexibility of the base rotation and the effectiveness of the braking mechanism.

4. Material and Workmanship Inspection
   Confirm that the frame material (steel, aluminum, solid wood) meets the order requirements without substitution of inferior materials. Check the density and resilience of the filling (foam, memory foam). Verify that the fabric material (mesh, leather, PVC) matches the order and is free from odors or excessive harmful substances (an environmental protection test report may be requested). The sewing workmanship should have even stitches without skipped stitches, and seams should be flat. Plastic parts should have smooth injection mold openings, and metal parts should have chamfered edges. For mesh chairs, check for uniform tension.

5. Functionality and Operation Inspection
   Test the smoothness and locking reliability of adjustable components such as gas lifts, armrests, headrests, and lumbar supports. For swivel chairs, verify that the base rotates without sticking or unusual noises and that the braking mechanism responds quickly. Simulate actual usage scenarios by placing a heavy object (over 120kg) on the seat for 1 hour and check for structural deformation or damage. For chairs with massage or heating functions, verify the safety of the electrical circuit and that the functions start normally.

6. Safety Inspection
   All edges should be rounded or blunted to prevent cuts from sharp edges. Check the security of small parts (screws, decorative caps) to prevent detachment and ingestion. Verify that the gas lift has passed certifications such as BIFMA or SGS and is free from explosion hazards. Ensure that materials comply with environmental standards such as REACH and RoHS, without excessive levels of harmful substances like formaldehyde or benzene. For chairs used in public places, check that the fabric has passed flame-retardant tests (such as CAL TB 117 standard).

7. Labeling and Packaging Inspection
   Check that the product labels on the chair are complete and clear.

8. Other Aspects
   Use sensory identification methods (such as observing leather texture, touching the feel, and assessing seat breathability) to assist in judging material quality. Check installation details to ensure that the furniture is level and properly aligned, screws are securely fastened, there are no missing or loose parts, and no installation debris remains at the site.
