3. Operating Instructions (Adjustments)
The Think Chair features five primary points of adjustability to customize your seating experience. These adjustments are designed to be intuitive.
Seat Height Adjustment: Locate the lever typically found under the right side of the seat. Lift the lever to raise the seat, or lift the lever while seated to lower the seat to your desired height. Ensure your feet are flat on the floor or a footrest, and your knees are at approximately a 90-degree angle.
Arm Adjustments (4D Arms): The chair is equipped with 4D adjustable arms. These allow for adjustments in four directions:
- Height: Press the button on the side of the armrest support and move the armrest up or down.
- Depth: Slide the arm cap forward or backward.
- Pivot: Rotate the arm cap inward or outward.
- Width: Some models allow the entire arm assembly to slide inward or outward from the seat base. Consult your specific model's instructions for this feature.
Adjust the arms so your elbows are at approximately a 90-degree angle when typing, supporting your forearms.
Back Recline and Tilt Tension: The chair's LiveBack Flexor System allows the backrest to move with your body. The tilt tension can be adjusted to control the resistance when reclining. A knob, usually located under the seat, can be turned to increase or decrease tension. Turn clockwise for more resistance, counter-clockwise for less.
Back Recline Lock: The chair offers 2 reclining positions. A lever, typically on the left side under the seat, allows you to lock the backrest in an upright or reclined position. Engage the lever to lock, disengage to allow free recline.
Lumbar Support: The chair features standard height-adjustable lower back support. This support is integrated into the backrest's flexors, which automatically change shape. For specific manual lumbar adjustments, if available on your model, refer to the detailed instructions provided with your chair. Generally, the lumbar support should align with the natural curve of your lower back.

4. Maintenance
To maintain the appearance and functionality of your Steelcase Think Chair, follow these simple care instructions:
- Cleaning: Wipe clean with a soft, damp cloth. For fabric surfaces, use a mild, non-abrasive cleaner if necessary, and test on an inconspicuous area first. Avoid harsh chemicals or abrasive materials that could damage the finish.
- Inspection: Periodically check all screws and fasteners to ensure they are tight. Retighten if necessary.
- Casters: Keep casters free of debris (hair, dust, etc.) to ensure smooth movement.
5. Troubleshooting
If you encounter any issues with your Steelcase Think Chair that are not resolved by adjusting the settings as described in Section 3, please consider the following general advice:
- Squeaking or Noise: Ensure all bolts and screws are tightened. A small amount of silicone spray on moving metal parts (avoiding fabric or plastic) may help, but consult Steelcase support if the issue persists.
- Difficulty Adjusting: Check for any obstructions or debris in the adjustment mechanisms. Ensure levers and knobs are fully engaged or disengaged.
- Instability: Verify that the chair is on a flat, even surface and that all casters are functioning correctly. Re-check assembly steps if recently assembled.
