3. Operation and Adjustments
Your Pinmoco chair offers several adjustments to optimize your comfort and posture.
- Height Adjustment: Use the lever located under the seat on the right side to adjust the chair's height. Lift the lever while seated to lower, or lift the lever while standing to raise the chair.
- Backrest Adjustment: The backrest features a 2-level adjustable height mechanism. Loosen the knob or lever at the back of the chair, adjust the backrest to your desired height, and then tighten to secure. This allows for personalized lumbar support.
- 360-Degree Swivel: Both the upper cushion and the footstool are designed to rotate 360 degrees, providing flexibility for various sitting positions and easy movement around your workspace.
- Footstool Usage: The extra-wide footstool is designed to support your legs, knees, and ankles when sitting cross-legged or in other alternative postures. Its height can be adjusted relative to the main seat from 0 to 4.7 inches, offering greater freedom to find a comfortable position.

4. Maintenance and Care
Proper care will extend the life and appearance of your Pinmoco office chair.
- Cleaning: The chair is upholstered with PU leather, which is easy to clean and waterproof. For general cleaning, wipe the surface with a soft, damp cloth. For tougher spots, use a mild soap solution and wipe dry immediately. Avoid harsh chemicals or abrasive cleaners.
- Caster Care: Periodically check the casters for accumulated dust or hair and clean them to ensure smooth rolling.
- Hardware Check: Every few months, inspect all screws and bolts to ensure they are tight. Re-tighten if necessary to maintain stability and safety.

5. Troubleshooting
If you encounter any issues with your chair, please refer to the following common solutions:
- Chair Squeaks: Check all bolts and screws and tighten them. Applying a small amount of silicone lubricant to moving parts (e.g., gas lift, tilt mechanism) may also help.
- Difficulty Adjusting Height: Ensure the height adjustment lever is fully engaged or disengaged. If the gas lift is unresponsive, it may require replacement.
- Casters Not Rolling Smoothly: Remove any debris (hair, lint) from the caster wheels. If casters are damaged, they may need to be replaced.
- Missing Parts or Bent Components: If you discover missing parts or a bent bar during assembly or use, please contact Pinmoco Direct customer service for assistance.
