- Insérer le vérin à gaz : Place the gas lift cylinder into the center hole of the assembled chair base. Ensure it is seated firmly.
- Mécanisme de fixation du siège : Alignez le mécanisme du siège avec les trous pré-percés sous le coussin. Fixez-le à l'aide des vis et de la clé Allen fournies. Assurez-vous que l'avant du mécanisme soit orienté vers l'avant du siège.

Mode d'emploi
Your ALFORDSON Arco-Grey chair offers several adjustment features to customize your seating experience.
1. Réglage de la hauteur du siège
To adjust the seat height, pull the lever located under the right side of the seat upwards. While holding the lever, stand up to raise the seat or remain seated and apply pressure to lower it. Release the lever to lock the height.
2. Fonction d'inclinaison du dossier
The backrest can recline up to 120 degrees. To recline, pull the lever located under the left side of the seat upwards and lean back. Release the lever at your desired angle to lock the recline. To return to an upright position, pull the lever again and lean forward slightly.
