Issues with Office Chairs After Long-Term Use

Office chairs may develop issues such as cleaning and maintenance problems, aging, and unusual noises after long-term use, requiring targeted solutions.

Cleaning and Maintenance Issues

• Cleaning: For mesh chairs, first use a vacuum cleaner to remove surface dust, then wipe with a damp cloth. For leather chairs, use a dedicated leather cleaner and avoid corrosive cleaners like alcohol and dish soap to prevent damage to the leather surface.
• Maintenance: Regularly clean dust from crevices to prevent accumulation that affects component flexibility. Occasionally apply lubricant to metal components such as gas cylinders, bases, and casters to reduce wear. Avoid prolonged exposure of the office chair to sunlight to prevent material aging. Avoid long-term heavy pressure, such as stacking heavy objects, to prevent structural deformation.

Aging Issues

• Service Life: The normal service life of an ordinary office swivel chair is typically 2-10 years, while high-end ergonomic chairs can last 10-15 years under ideal conditions. Using a chair for over a decade far exceeds the average lifespan of ordinary products, making aging of core components and materials inevitable.
• Inspection and Safety Assessment of Aging Core Components:
  • Gas Cylinder (Lifting Rod): Check if the lifting process is smooth, uniform, and free of jams. Press the seat to see if there is any obvious cushioning or air leakage sound. Test if the chair is completely unable to lift, slowly sinks, or has lifting jams. Check for official manufacturer logos and qualification stamps, such as authoritative safety certifications like SGS, BIFMA, and TUV. Lightly tap with a metal object; a clear sound usually indicates steel, which is relatively safe, while a muffled sound may indicate electroplated iron, which is more dangerous.
  • Base and Five-Star Bracket: Check for deformation at connections, loose screws, whether the base is loose or makes unusual noises, and if rotation is smooth.
  • Casters and Upholstery/Seat Cushion: Check if the casters are severely worn, do not rotate smoothly, or have axle misalignment. Check if the seat cushion foam/mesh is sagging. For mild sagging (less than 1 cm), try flipping the foam cushion or adjusting the straps under the mesh chair to tighten them. For severe sagging, consider replacing the filling or the entire seat cushion.

Unusual Noise Issues

• Loose Connection Screws: Tighten the screws at all connections of the backrest, armrests, base, and chair legs.
• Lack of Lubrication in Base Rotating Shaft: For chairs with a rocking and reclining function, add lubricant to the internal metal springs and rotating shaft positions.
• Wear at the Connection between the Gas Cylinder and Five-Star Foot: Check the contact positions at the top of the gas cylinder and the base, and at the bottom and the five-star foot. Replace components if necessary.
• Aging and Deformation of Plastic Frame Components: Low-priced chairs often have thin plastic frames. After prolonged sitting and pressure, slight deformation, structural compression, and continuous friction in the gaps can cause unusual noises, which are generally difficult to completely repair. Consider replacing the chair.
• Dry and Jammed Wheel Bearings: Add lubricant to the internal bearings of the wheels.
