Why Do Ergonomic Chair Factories Emphasize Certified Gas Lifts?

For every office chair manufacturer and ergonomic chair factory, the safety and stability of each component directly affect product quality and brand reputation. Among all parts, the gas lift is one of the most critical — it contains high-pressure gas that supports smooth seat height adjustment. Its performance determines the stability, durability, and most importantly, safety of the chair.

For mesh chair suppliers and office furniture retailers, understanding the importance of gas lift certification is essential to identifying high-quality office chairs and ensuring product reliability for end users.
        

1. Why Does the Gas Lift Need Certification?

A gas lift bears repeated lifting, lowering, and side pressure during daily use. Using an uncertified or poor-quality gas lift could lead to leakage, deformation, or even explosion — posing serious safety risks.

That’s why the International Organization for Standardization (ISO) and national testing agencies have established strict testing and certification standards. Obtaining these certifications is not only a requirement for safe market entry but also a key qualification for office chair manufacturers and ergonomic chair factories to access international markets.

2. What Are the Main Certification Standards?

The most recognized and advanced certification worldwide is the ISO 12599 series, which covers comprehensive testing for performance, safety, and durability. A certified gas lift typically undergoes the following tests:

Durability Test: Simulates long-term use, requiring the gas lift to perform tens of thousands of lift cycles without leakage, deformation, or malfunction.

Burst Pressure Test: Subjects the gas lift to extreme pressure levels beyond normal working conditions to ensure it will not explode even under abnormal stress.

Eccentric Load Test: Tests the gas lift’s stability under side loads — simulating uneven sitting posture or off-center pressure — to prevent bending or failure.

Static Load Test: Examines the lift’s ability to safely support loads well above standard body weight without collapsing.

Gas lifts that pass these rigorous tests are awarded official certification marks. For ergonomic chair factories, this represents a strong commitment to quality and user safety. For office furniture retailers, wholesalers, and project buyers, it serves as an important indicator of trustworthy and long-lasting products.

Choosing certified gas lifts is not just a technical requirement — it’s a clear sign of professionalism and integrity for every office chair manufacturer and mesh chair supplier, and a symbol of reliability for every office furniture retailer bringing safe, high-quality seating to customers.
