Setup and Assembly
Assembly is required for this chair. Please follow the instructions provided in the separate assembly guide included with your product. Ensure all components are present and undamaged before beginning assembly. Typically, assembly involves attaching the base to the seat, connecting the backrest, and securing the armrests. It is recommended to assemble the chair on a soft, clean surface to prevent scratches.
Estimated Assembly Time: Approximately 10-20 minutes.
Tools Required: Usually an Allen wrench (often included).
Operating Instructions
Your FlexFit Hyken Mesh Task Chair offers multiple adjustment points to customize your seating experience for optimal comfort and ergonomic support.
1. Seat Height Adjustment
- Locate the lever on the right side, beneath the seat.
- To raise the seat: Lift the lever while taking your weight off the seat. The seat will rise automatically.
- To lower the seat: Lift the lever while remaining seated. The seat will lower under your weight.
- Release the lever to lock the seat at the desired height.
2. Armrest Height Adjustment
- Press the button located on the side of each armrest support.
- While holding the button, slide the armrest up or down to your preferred height.
- Release the button to lock the armrest in place.
3. Headrest Adjustment
- The headrest can be adjusted for both height and angle.
- Gently push or pull the headrest to adjust its angle.
- To adjust height, firmly pull the headrest upwards or push downwards. It will click into various positions.
4. Lumbar Support Adjustment
- The integrated lumbar support is designed to conform to your back.
- Adjustments for lumbar support are typically integrated with the backrest's overall design and may not have separate controls. Ensure the backrest is positioned correctly for optimal support.
5. Tilt Tension and Lock
- Tilt Tension: The tension knob located underneath the seat (usually at the front) allows you to adjust the resistance of the chair for reclining. Turn clockwise to increase tension (harder to recline) and counter-clockwise to decrease tension (easier to recline).
- Tilt Lock: Use the lever on the left side (or combined with the seat height lever) to lock the backrest in an upright position or in one of the three reclining lock positions. Push the lever in to lock, pull out to unlock and allow tilting.
Maintenance
Regular maintenance will help prolong the life and appearance of your chair.
- Cleaning Mesh: Use a soft cloth dampened with mild soap and water. Do not use abrasive cleaners or solvents.
- Cleaning Base and Casters: Wipe with a damp cloth. Periodically check casters for hair or debris and clean as needed to ensure smooth rolling.
- Hardware: Periodically check all screws and bolts to ensure they are tight. Retighten if necessary.
- Avoid Direct Sunlight: Prolonged exposure to direct sunlight can cause the mesh and plastic components to fade or degrade.
Troubleshooting
