Office Chair Seat & Backrest Combined Testing System – Simulate Real-World Fatigue & Safety

BIFMA X5.1, EN 1335 & ANSI/BIFMA Certified for Full Chair Durability Validation
Our Seat-Back Integrated Testing Machine replicates years of sitting, reclining, and dynamic loads in one system, ensuring office chairs meet global ergonomic and structural safety standards.

Core Testing Capabilities

Synchronized Multi-Axis Testing

Static Load:
- Seat: 1500N vertical force (simulate 200kg user).
- Backrest: 800N horizontal/vertical force (leaning & reclining).
Cyclic Fatigue:
- 100,000+ cycles at 1–10 Hz (seat) + 0.5–5 Hz (backrest).
- Synchronized motion for seat tilt & backrest recline (±30°).
Impact Resistance:
- Seat drop test (25kg weight from 150mm height).
- Backrest impact (15J energy via pendulum module).

Smart Control & Precision

Force Accuracy: ±0.5% FS via 6-axis load cells.
Displacement Control: 0.01mm resolution (seat) + 0.1° angular precision (backrest).
Real-Time Monitoring: 3D deformation mapping with laser scanners.

Automation & Compliance

Pre-Set Profiles: BIFMA X5.1, EN 1335, GB/T 22894, ANSI/BIFMA.
Auto-Adjust Fixtures: Robotic arms adapt to chair sizes (seat width: 400–600mm; backrest height: 500–900mm).
Fail-Safe Logic: Stop tests upon detecting fractures, excessive deformation, or load drops.

Customer Success Stories

“This machine’s synchronized testing exposed a critical weak point where the seat meets the backrest – something single-axis testers missed.”
– ErgoChair Innovations, Canada

“We reduced certification time from 14 days to 3 days by testing seat and backrest simultaneously.”
– Asia Furniture Testing Lab, China

FAQ

Q: Can it test chairs with headrests and armrests?
A: Yes! Optional fixtures add headrest compression and armrest load tests.

Q: How to test electric reclining chairs?
A: Integrate with our power module to simulate motorized tilt cycles.

Q: What’s the minimum chair size supported?
A: Seat depth ≥380mm, backrest height ≥450mm (custom fixtures for smaller sizes).

Q: Is environmental testing possible (heat/cold)?
A: Add thermal chambers (-30°C to +80°C) for material performance under extreme conditions.
