5. Mode d'emploi
5.1. Réglage de la hauteur
To adjust the seat height, locate the lever on the right side beneath the seat. While seated, pull the lever up to lower the seat. To raise the seat, stand up and pull the lever up. Release the lever at the desired height to lock it in place.
Image 5.1: The chair features adjustable height, 360-degree rotation, and flexible casters for various floor types.
5.2. Armrest Adjustment (Flip-up Function)
The armrests are designed to flip up 90 degrees. To raise an armrest, simply lift it upwards until it locks into the vertical position. To lower it, pull it down. This feature allows the chair to be stored under a desk, saving space.

5.3. Tilt/Rocking Function
The chair features a 120-degree tilt tension and rocking function. Locate the lever on the left side beneath the seat.
- Engage/Disengage Rocking: Pull the lever outwards to enable the rocking function. Push it inwards to lock the backrest in an upright position.
- Régler la tension d'inclinaison : The round knob located at the front center beneath the seat controls the tilt tension. Turn clockwise to tighten the tension (making it harder to recline) and counter-clockwise to loosen it (making it easier to recline).

5.4. Pivotant et roulettes
The chair offers a full 360-degree swivel for ease of movement. The flexible casters are designed for smooth rolling on various floor surfaces, including marble, wood, and carpet.

6. Entretien
6.1. Nettoyage
- Nettoyer avec une publicitéamp chiffon. Évitez les produits chimiques agressifs ou les nettoyants abrasifs.
- For the mesh backrest and fabric seat, use a vacuum cleaner with a brush attachment to remove dust and debris.
- Periodically check and clean the casters to ensure smooth movement and prevent floor damage.
6.2. Soins généraux
- Regularly inspect all screws and connections to ensure they remain tight. Retighten as necessary.
- Avoid prolonged exposure to direct sunlight to prevent fading of materials.
- Do not place hot items directly on the chair's surfaces.
7. Dépannage
- Grincements de chaises : Check all bolted connections and tighten if loose. A small amount of silicone lubricant can be applied to moving parts if the squeaking persists.
- Difficulté à régler la hauteur : Vérifiez que le levier de vérin à gaz est bien enclenché. Si le problème persiste, il faudra peut-être remplacer le vérin.
- Roulettes ne roulant pas correctement : Remove any hair or debris wrapped around the caster wheels. Clean the wheels and their housings.
- La chaise semble instable : Verify that the chair is on a flat surface and all components, especially the base and backrest, are securely attached.
- Seat Cushion Flattening: Over time, seat cushions may compress. While this is normal wear, if it significantly impacts comfort, consider adding a supplementary cushion or contacting customer support for options.
