Office Chair Dual Certification
Admin October 16, 2026
The Pirate Ship TC80 chair has obtained dual certification from the BIFMA X5.1 Commercial Office Furniture Standard and the EN 1335 European Office Chair Specification. The following provides an introduction from two aspects: certification standard content and certification significance:

Certification Standard Content
- BIFMA X5.1 Commercial Office Furniture Standard: This standard primarily focuses on dynamic fatigue and structural integrity in commercial environments. In commercial office settings, office chairs are used frequently and for extended periods, and may face various complex dynamic usage scenarios, such as frequent sitting, standing, turning, and reclining. The BIFMA X5.1 standard evaluates the structural strength and component durability of office chairs through a series of rigorous tests that simulate these dynamic usage processes. Only by passing these tests can it be proven that the office chair can be used stably for a long time in a commercial environment without experiencing structural damage or component loosening due to frequent dynamic operations.
- EN 1335 European Office Chair Specification: This specification strictly regulates size classification and static load requirements in the European market. People with different body types and usage needs have different requirements for the size of office chairs. EN 1335 clearly classifies the seat height, seat depth, backrest height, and other dimensions of office chairs to ensure they can meet the needs of different users. At the same time, the static load requirements focus on the stability and safety of office chairs when bearing a certain weight, such as the maximum weight the chair can bear in a stationary state and the absence of deformation during long-term weight bearing.
Certification Significance
- Product Quality Assurance: Dual certification means that the Pirate Ship TC80 chair has reached a high level in terms of structure and performance. The dynamic fatigue test of BIFMA X5.1 ensures the durability of the chair during frequent use, while the size classification and static load requirements of EN 1335 ensure the rationality of the chair's size and its safety during use.
- Enhanced Market Competitiveness: In the fiercely competitive office chair market, obtaining dual certification is a strong proof of product quality. This helps the Pirate Ship TC80 chair gain the trust of consumers in the European market and other regions that recognize these standards, thereby improving its market competitiveness.
