Operating Instructions
The FLEXISPOT ErgoX-PRO chair offers multiple adjustment options to customize your seating experience for optimal comfort and support.
Chair Adjustments:
- Seat Height Adjustment: Locate the lever on the right side beneath the seat. Pull the lever up to raise the seat; release to lock. To lower, pull the lever up while seated.
- Seat Depth Adjustment: Use the lever on the left side beneath the seat to slide the seat forward or backward by 2.8 inches (7cm), accommodating different thigh lengths.
- Backrest Recline and Tilt Lock: The chair features a 3-position tilt base (90°/115°/135°). Use the recline lever to adjust the angle and lock it into your desired position. The 12-level fine-tuned backrest with spring cushioning ensures natural movement.
- 5D Dynamic Lumbar Support: The lumbar support is designed to adapt to your posture. It can be adjusted for height and depth to provide targeted support to your lower back.
- 4D Adjustable Headrest: The headrest can be adjusted for height, angle (45°, 160°, 120° rotation), and front/back position (1.8 inches) to support your head and neck. It can also function as a back cushion.
- 7D Linkage Armrests: These full-motion armrests move with your body. Adjust them for height (3 inches up/down), rotation (40°), left/right movement (360°), and front/back (2.4 inches) to provide continuous support for various activities.
- Footrest (if applicable): Extend the footrest from beneath the seat for additional relaxation. It offers 9° adaptive fine-tuning.

Maintenance
To ensure the longevity and optimal performance of your FLEXISPOT ErgoX-PRO chair, regular maintenance is recommended.
- Cleaning: For general cleaning, use a soft, damp cloth. For the mesh components, dry clean only. Avoid harsh chemicals or abrasive cleaners.
- Inspection: Periodically check all screws and bolts to ensure they are tight. Re-tighten if necessary.
- Caster Care: Keep the casters free of hair and debris to ensure smooth movement.
Troubleshooting
If you encounter any issues with your chair, please refer to the following common solutions:
- Chair Does Not Adjust Height: Ensure the gas lift lever is fully engaged or disengaged as required. Check if the gas lift cylinder is properly seated in the base and mechanism.
- Backrest Tilt Not Working: Verify that the tilt lock mechanism is disengaged. Some users report needing to apply more force or adjust the tension knob (if present) to achieve desired tilt.
- Armrests Move Too Easily: The 7D armrests are designed for dynamic movement. If they feel excessively loose, ensure all assembly screws are securely tightened.
- Squeaking Noises: Check all connection points and tighten any loose screws. Applying a small amount of silicone lubricant to moving parts (e.g., gas lift, tilt mechanism) can help.
- Chair Feels Unstable: Re-check all assembly steps to ensure all components are correctly installed and tightened. Ensure the chair is on a flat, even surface.
If these steps do not resolve the issue, please contact FLEXISPOT customer support for further assistance.
