Office Chair Aging

Admin October 08, 2026

Office chair aging involves multiple issues such as component performance degradation, overall performance reduction, and appearance damage.

Component Performance Degradation

  • Gas Spring Aging: The gas spring is a crucial component of an office chair, and its aging often manifests as excessive sinking. The internal sealing ring, typically made of polyurethane or high-performance rubber composites, undergoes stress relaxation, oxidative degradation, and the accumulation of microscopic cracks over time due to continuous reciprocating sliding, load compression, and temperature and humidity variations. This leads to a decline in sealing performance, allowing high-pressure nitrogen to escape and accelerating the sinking speed. Additionally, factors such as scratches on the piston rod surface, the deposition of lubricant oxides on the inner wall of the cylinder, and environmental temperature differences can also contribute to excessive sinking of the gas spring.
  • Cushion Foam Aging: Over time, the cushion foam in office chairs can experience permanent compression deformation, collapsing like an old mattress and failing to rebound. The support surface that originally evenly distributed the pressure on the buttocks disappears, causing the body weight to concentrate on the ischial tuberosities. This leads to repeated soreness in the ischial region and strains the surrounding lumbar muscles, resulting in lower back pain.

Overall Performance Reduction

After prolonged use, issues such as loose screws and worn connectors gradually emerge, leading to a decline in the stability of the office chair. This affects employee work efficiency and may even cause accidental injuries. The elasticity of the seat cushion and backrest weakens, reducing comfort and impacting the employee's work experience. Aging office chairs often fail to meet ergonomic requirements, such as non-adjustable seat height and fixed backrest angles, increasing the burden on the employee's lumbar and cervical spine. Long-term use may lead to health problems such as lower back pain and cervical spondylosis. There are also potential damage risks, such as seat breakage that may cause employees to fall and loose screws that may lead to chair collapse, posing a threat to employee health.

Appearance Damage

Aging office chairs may exhibit problems such as scratches, color differences, and fading, providing a poor visual experience for employees and visiting clients and affecting the company's image and cultural atmosphere. During use, they may also produce squeaking noises, affecting employee work efficiency and disturbing colleagues nearby.

Maintenance Recommendations

When cleaning, avoid scrubbing vigorously to prevent damage to the surface. For leather sofas and office chairs that have been used for a long time or accidentally stained, wipe them with a cloth dampened with an appropriate concentration of soapy water (or laundry detergent, with a water content of 40% - 50%), then rinse with clean water and dry with a clean cloth. Do not use harsh cleaning agents. When using, try to keep the center of gravity in the middle of the gas spring. Regularly check for loose screws, springs, and knobs on office chairs that have been used for a long time, and adjust the spring tension according to the user's body weight. Do not sit on the armrests or place heavy objects on them. Follow the instructions for regular maintenance and avoid prolonged exposure to sunlight.
