Frequently Asked Questions

Technical Specifications & Compatibility

Q: What is the taper specification of the center hole? How do you ensure compatibility with our gas lifts?
A: We utilize a precision 1:10 taper (half-angle 1°26′16"). This ensures a tight-tolerance fit with standard gas lifts, effectively preventing wobbling, tilting, or abnormal noise after long-term use.

Q: What is the specification for the caster mounting holes? Is it compatible with mainstream casters?
A: The base comes standard with an international 11mm socket diameter. This ensures that stem casters remain perfectly vertical and secure without tilting after installation.

Q: What are the vertical height and radius measurements of the chair base?
A: The vertical height are 72, 77, 88, 89mm and the radius are 280, 300, 320, 350mm. We provide detailed technical drawings with these measurements to help your R&D team pre-calculate the minimum seat height, ensuring the final chair meets international ergonomic standards.

Structural Strength & Compliance

Q: What is the material composition of this chair base? How is high load capacity guaranteed?
A: We utilize PA+G Material. Compared to standard plastics, we have increased the glass fiber ratio to enhance fatigue resistance and impact strength, ensuring safety during high-frequency commercial use. Additionally, the base features an internal star-shaped reinforcement rib design, which maximizes bending resistance and structural integrity.

Procurement, Logistics & Supply Chain Flexibility

Q: What is the Minimum Order Quantity? Do you support bulk exports and provide Certificates of Origin?
A: We fully support large-scale OEM/ODM procurement and possess extensive export experience. As a Taiwan-based manufacturer, we can provide a Certificate of Origin to facilitate your global market strategy, helping you optimize import duties and streamline customs clearance.

Q: Do you offer full chair assembly or knocked-down shipping options?
A: We offer flexible shipping configurations. You may purchase components individually, or entrust us to integrate other parts for complete chair assembly or Knocked-Down shipping. This flexibility is designed to reduce assembly complexity at your end-destination and optimize container space.
