Round-the-clock Testing: Stricter than Standard

The Youjin Testing Lab is our ultimate backbone for R&D and mass production. Our in-house test room is fully equipped with advanced testing machinery, subjecting every model to endurance runs far exceeding regular BIFMA standards.

• Backrest Cycles: Simulating 120,000 backward pushes to prove lifetime structural integrity.
• Swivel Swings: Swiveling 100,000 times under heavy loads to ensure smooth rotation.
• Castor Wear Run: Heavy-load castor run over obstacles for miles to confirm resilience.
