A: We support a wide range of international trade terms to suit your logistics needs, including EXW, FOB, C&F, DDP, and DDU.
Q7: What is the difference application between 4 leg base, five star base, and round base?
  • 4-Leg Base: Best for static seating like dining, guest, or conference chairs. Offers a clean, minimalist aesthetic.
  • 5-Star Base: The industry standard for mobile task and office chairs. It provides optimal balance and prevents tipping when rolling, strictly meeting BIFMA safety requirements.
  • Round Base: Ideal for lounge chairs, bar stools, and salon seating. Its solid weight lowers the center of gravity, offering maximum stability for reclining or height-adjustable furniture.
Q8: What kind of functions does a chair base support?
Beyond simply holding the chair up, a professional seating base serves four critical structural functions:
  • Weight Distribution: Safely disperses the user’s weight to the floor, ensuring structural integrity under heavy static and dynamic loads.
  • Central Hub for Adjustability: Features a reinforced center taper to securely house the gas cylinder. Depending on the cylinder paired, this connection enables standard height adjustment and 360-degree swivel, as well as specialized functions like fixed (non-rotating) positioning or auto-return (repositioning) for conference and lounge seating.
  • Dynamic Mobility: Acts as the anchor point for casters or glides, allowing smooth, balanced movement across various floor types.
  • Anti-Tip Stability: The calculated span (radius) and geometry of the legs prevent the chair from tipping over during deep recline or sudden movements, keeping the chair compliant with BIFMA safety standards.
Q9: Which base material should I choose for my chair or table?
  • Aluminum: The premium choice for executive and high-end ergonomic chairs. Lightweight, highly durable, and offers an elegant polished or brushed finish.
  • Nylon: Cost-effective, flexible, and highly resilient. Perfect for standard office and daily task chairs.
  • Steel (Chrome/Powder Coated): Excellent for heavy-duty applications, offering maximum load capacity and a modern industrial look.
Q10: How do I select the right base radius for different types of furniture?
The base radius must support the chair’s center of gravity to prevent tipping, especially when the tilt mechanism is engaged.
  • Small (Radius 300-320mm): For stools, kids’ chairs, or compact armless task chairs.
  • Standard (Radius 320-350mm): For regular office and management chairs.
  • Large (Radius 350-380mm+): Mandatory for heavy executive chairs, 24/7 intensive use seating, or chairs with deep-tilt mechanisms to ensure BIFMA-compliant anti-tip safety.
