5. Operating Instructions
Your Mimoglad OC-5188 chair features several adjustable components to customize your seating experience:
- Height Adjustment: Locate the lever under the right side of the seat. To raise the seat, lift the lever while taking your weight off the chair. To lower the seat, lift the lever while seated. The chair offers approximately 4 inches of height adjustment.
- Lumbar Support Adjustment: The lumbar support can be adjusted vertically by approximately 2 inches to provide optimal support for your lower back. Gently push or pull the lumbar support pad up or down to your preferred position.
- Tilt/Rocking Function: The chair features a rocking function that allows the backrest to recline from 90 to 135 degrees. Use the tension knob located under the seat to adjust the resistance of the rocking motion. Pull the lever out to enable rocking, and push it in to lock the chair in an upright position.
- Flip-Up Armrests: The armrests can be flipped up 90 degrees, allowing the chair to be pushed closer to a desk or for easier entry and exit.
- 360-Degree Swivel: The chair is designed with a 360-degree swivel function for easy movement and access within your workspace.

6. Maintenance
Proper care and maintenance will extend the life of your Mimoglad office chair:

- Fabric Seat Care: For the fabric seat cushion, spot clean with a mild fabric cleaner if necessary. Test on an inconspicuous area first.
- Hardware Check: Periodically check all bolts and screws to ensure they are tight. Re-tighten as needed to maintain stability and safety.
- Caster Care: Keep casters free of hair and debris to ensure smooth rolling.
