3. Operating Instructions

Your SMUG Office Chair offers several adjustable features to customize your seating experience:

3.1 Seat Height Adjustment

To adjust the seat height, locate the pneumatic adjustment lever under the seat on the right side. 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 your desired height.

3.2 Rocking Mode

To activate the rocking mode, pull the same lever (used for height adjustment) outwards. The chair will now allow for a gentle rocking motion. Push the lever inwards to lock the chair in an upright position.

3.3 Armrest Functionality

The armrests on your SMUG chair are designed to flip up. This feature allows you to push the chair closer to your desk, saving space when not in use, or to provide more freedom of movement. Simply lift the armrests upwards until they lock into a vertical position. To return them to the horizontal position, pull them down.
