Step 2: Insert Gas Lift into Base

Step 3: Attach Mechanism Plate to Seat Cushion
Align the mechanism plate with the screw holes on the underside of the seat cushion. Secure it using the provided screws from the hardware kit. Ensure the 'FRONT' arrow (if present) on the mechanism points towards the front of the seat.
Step 4: Attach Armrests to Seat Cushion
Attach the armrests to the sides of the seat cushion using the designated screws. Do not overtighten initially.
Step 5: Attach Backrest to Seat Cushion and Armrests

Operating Your Chair
Seat Height Adjustment
To adjust the seat height, locate the lever on the right side of the seat. To raise the seat, lift your weight off the chair while pulling the lever upwards. To lower the seat, remain seated and pull the lever upwards.

Backrest Tilt Function
To recline the backrest, pull the lever on the left side of the seat outwards. This will unlock the backrest, allowing it to tilt. To lock the backrest in an upright position, push the lever inwards. The chair allows for a comfortable rocking motion when unlocked.
Tilt Tension Adjustment
The round knob located under the front of the seat controls the tilt tension. Turn the knob clockwise to increase tension (making it harder to recline) or counter-clockwise to decrease tension (making it easier to recline).

Adjustable Headrest
The headrest can be adjusted vertically by sliding it up or down to find your optimal neck support. It can also be rotated slightly for fine-tuning the angle.
Lumbar Support Adjustment
The integrated lumbar support is designed to provide optimal support for your lower back. Adjustments typically involve sliding or rotating a mechanism on the backrest to position the support where it feels most comfortable for you.

Care and Maintenance
Cleaning
- For mesh and fabric surfaces, use a soft cloth dampened with mild soap and water. Gently wipe the affected areas. Do not use harsh chemicals, abrasive cleaners, or bleach, as these can damage the material.
- Wipe plastic and metal parts with a damp cloth. Dry immediately to prevent water spots or corrosion.
- Avoid excessive moisture. If the chair becomes wet, dry it thoroughly before use.
General Care
- Regularly check all screws and bolts to ensure they are tight. Retighten as necessary to maintain stability and prevent squeaking.
- Keep the chair away from direct sunlight and heat sources (e.g., radiators, fireplaces) to prevent material degradation, fading, or warping.
- Avoid standing on the chair or using it for purposes other than its intended use as an office chair.
Troubleshooting Guide
Issue: Chair does not adjust height.
Solution: Ensure the gas lift lever is fully engaged. Check if the gas lift cylinder is properly seated in both the base and the mechanism plate. If the issue persists, the gas lift may be faulty and require replacement.
Issue: Chair squeaks or wobbles.
Solution: Check all assembly screws and bolts and tighten them securely. Ensure the casters are fully inserted into the base. If squeaking persists, a small amount of silicone-based lubricant can be applied to moving parts, avoiding contact with fabric.
Issue: Backrest does not recline or lock.
Solution: Verify that the tilt lock lever is correctly engaged or disengaged. Adjust the tilt tension knob (located under the seat) to ensure it's not too tight or too loose, which can affect the recline mechanism.
