4. Assembly Instructions
Assembly is straightforward and typically takes about 20 minutes. Two tools are included for your convenience. It is recommended to have assistance for attaching the armrests.
- Attach Casters to Star Base: Insert each of the five casters into the holes at the end of the star base legs. Push firmly until they click into place.
- Insert Gas Lift: Place the gas lift cylinder into the central hole of the star base.
- Attach Mechanism Plate to Seat: Align the mechanism plate with the screw holes on the underside of the seat cushion. Ensure the front of the mechanism plate faces the front of the seat. Secure with screws and washers using the provided Allen key.
- Attach Armrests to Seat and Backrest: Position the armrests on the sides of the seat cushion, aligning the holes. Secure the armrests to the seat using screws. Then, align the backrest with the upper holes of the armrests and the back of the seat. Secure the backrest to the armrests and seat. Note: It may require some force to align the holes correctly, especially for the backrest. Screw gradually and evenly on both sides.
- Connect Seat Assembly to Gas Lift: Carefully place the assembled seat and backrest onto the gas lift cylinder, ensuring the central hole of the mechanism plate aligns with the top of the gas lift.
Once assembled, ensure all connections are tight and the chair feels stable before use.
5. Operating Instructions
Your tectake office chair offers several adjustment features to customize your seating experience for optimal comfort and ergonomic support.
5.1 Height Adjustment
To adjust the seat height:
- To raise: While standing, pull the lever located on the right side of the seat upwards. The seat will rise automatically. Release the lever when the desired height is reached.
- To lower: While seated, pull the lever located on the right side of the seat upwards. The seat will lower. Release the lever when the desired height is reached.
5.2 Tilt Mechanism and Tension Adjustment
The chair features a continuous tilt mechanism that allows the backrest and seat to recline together. The tension of this tilt can be adjusted to suit your weight and preference.
- To activate/deactivate tilt: Pull the same lever used for height adjustment outwards to enable the tilt function. Push it inwards to lock the chair in an upright position.
- To adjust tilt tension: Rotate the round knob located underneath the front of the seat. Turn clockwise to increase tension (making it harder to recline) and counter-clockwise to decrease tension (making it easier to recline).
5.3 Ergonomic Support
The chair's design, including the padded backrest and headrest, provides ergonomic support to promote a healthy posture and reduce fatigue during extended use.

6. Maintenance and Care
Proper care will extend the life and appearance of your tectake office chair.
- Cleaning: The synthetic leather material should be dry cleaned. For minor spills, wipe immediately with a soft, damp cloth and mild soap, then dry thoroughly. Avoid harsh chemicals or abrasive cleaners.
- Regular Inspection: Periodically check all screws and bolts to ensure they remain tight. Re-tighten if necessary.
- Lubrication: If the tilt mechanism or casters begin to squeak, a small amount of silicone-based lubricant can be applied to the moving parts.
- Avoid Direct Sunlight: Prolonged exposure to direct sunlight can cause the synthetic leather to fade or crack.
7. Troubleshooting
Here are solutions to common issues you might encounter with your office chair:
| Problem | Possible Cause | Solution |
|---|---|---|
| Chair does not adjust height | Gas lift cylinder is faulty or lever is not engaged correctly. | Ensure the lever is fully pulled up. If the issue persists, the gas lift may need replacement. Contact support. |
| Chair wobbles or is unstable | Loose screws or uneven floor. | Check and tighten all assembly screws, especially those connecting the armrests and mechanism plate. Ensure the chair is on a flat surface. |
| Squeaking noise during movement | Friction in moving parts (e.g., tilt mechanism, casters). | Apply a small amount of silicone-based lubricant to the pivot points of the tilt mechanism and caster stems. |
| Casters do not roll smoothly | Debris caught in casters or worn casters. | Clean any hair or debris from the caster wheels. If casters are worn, they may need replacement. |
| Tilt mechanism is too stiff or too loose | Tilt tension knob needs adjustment. | Rotate the tilt tension knob underneath the seat to increase or decrease resistance. |
