5. Operating Instructions

Your HeroSet HS5199 chair offers several adjustable features for personalized comfort.

5.1. Height Adjustment

To adjust the chair height, locate the lever on the right side beneath the seat. While seated, pull the lever up to lower the chair. To raise the chair, stand up and pull the lever up. Release the lever at the desired height.

5.2. Rocking Function and Recline Lock

The chair features a rocking function that allows the backrest to recline between 90 and 120 degrees. To activate the rocking function, pull the lever on the left side of the seat outwards. To lock the backrest in an upright position (90 degrees) or a reclined position (up to 120 degrees), push the lever inwards at your desired angle.

5.3. Tilt Tension Adjustment

Beneath the seat, at the front of the mechanism plate, you will find a round knob. Rotate this knob clockwise to increase the tension, making the rocking motion stiffer. Rotate it counter-clockwise to decrease the tension, allowing for easier rocking.

5.4. Flip-Up Armrests

The armrests can be flipped up 90 degrees to allow the chair to be pushed closer to a desk or for increased spatial freedom. Simply lift the armrests upwards until they lock into the vertical position. To return them, gently pull them down.

5.5. 360-Degree Swivel and Casters

The chair is equipped with a 360-degree swivel function for easy movement and access. The durable PU casters are designed to roll smoothly on various floor types, including terrazzo, ceramic tile, carpet, and wood board.
