5. Operating Instructions (Adjustments)

The MARKUS chair offers several adjustments to customize your seating experience for optimal comfort and support.

5.1. Seat Height Adjustment

To adjust the seat height, locate the lever on the right side, beneath the seat. Pull the lever upwards while seated to lower the seat, or pull the lever upwards while standing to raise the seat. Release the lever at the desired height.

5.2. Tilt Mechanism Adjustment

The chair features an adjustable and lockable tilt function. Locate the second lever, typically on the left side beneath the seat. Pull the lever outwards to unlock the tilt function, allowing the backrest and seat to recline. Push the lever inwards to lock the tilt in an upright or reclined position. A knob, usually at the front under the seat, can be rotated to adjust the tension of the tilt mechanism, making it easier or harder to recline.

5.3. Lumbar Support

The MARKUS chair includes built-in lumbar support designed to provide relief and support to your lower back. This support is integrated into the backrest and does not require manual adjustment.

5.4. Safety Castors

The chair is equipped with pressure-sensitive castors. These castors are designed to brake automatically when you stand up, preventing the chair from rolling away. When you sit down, the pressure releases the brake, allowing the chair to move freely.

6. Care and Maintenance

Proper care and maintenance will extend the lifespan of your IKEA MARKUS Office Chair.

6.1. Cleaning Instructions

• Fabric/Mesh: Wipe clean with a damp cloth. For tougher stains, use a mild soap solution and then wipe dry. Do not use harsh chemicals or abrasive cleaners.
• Plastic/Metal Parts: Wipe clean with a damp cloth.

6.2. General Maintenance

• Periodically check all screws and bolts to ensure they are tight. Retighten as necessary.
• Inspect castors for any debris or hair that might impede movement. Clean if necessary.
• Avoid exposing the chair to direct sunlight or extreme temperatures for prolonged periods.

7. Troubleshooting

This section addresses common issues you might encounter with your office chair.

7.1. Chair Does Not Adjust Height

• Check Gas Lift: Ensure the gas lift lever is fully engaged. If the gas lift is faulty, it may need replacement.
• Obstruction: Verify there are no obstructions preventing the lever from moving freely.

7.2. Chair Squeaks or Wobbles

• Tighten Screws: Most squeaking or wobbling is caused by loose screws. Carefully inspect and tighten all assembly screws, especially those connecting the seat, backrest, and armrests.
• Lubrication: A small amount of silicone spray on moving metal parts (avoiding the gas lift cylinder) can reduce squeaking.

7.3. Castors Not Rolling Smoothly

• Clean Castors: Remove any hair, dust, or debris that may be caught in the castor wheels.
• Surface Compatibility: Ensure the castors are suitable for your flooring type.
