3. Opsætning og montering

- Placer stolen på en flad, stabil overflade.
3.2 Komponentmontering
Follow the specific assembly instructions provided in the separate assembly guide included with your chair. Typically, this involves:
- Attaching the footrest assembly to the main chair frame.
- Connecting any necessary cables between the footrest and the main unit.
- Securing the side panels or armrests, if they are separate components.
- Connecting the power cord to the chair and then to a grounded electrical outlet.
