This is an intentional design feature built to provide stable, reliable arm support while preventing the mechanism from loosening over time.

Stability & Support: The armrest width adjustment is designed with higher resistance to keep your arms securely supported and prevent wobbling during use.

Long-Term Durability: This added tension ensures the adjustment mechanism remains reliable even after years of extended use.

Recommended Action: Try adjusting the armrests back and forth several times. As the internal components are used, the parts will settle in and the movement will naturally become smoother.

Further Assistance: If the adjustment still feels too stiff after repeated use, please record a short video of the movement and contact our support team.
