How to use

Adjust the seat height with the gas lift lever so that your thighs are approximately parallel to the floor and your feet rest flat. Sit with the contoured seat supporting your pelvis and the backrest supporting the lower back at its 430 mm height. Use casters to move short distances; avoid dragging the chair on uneven surfaces. If required, install one of the optional armrests by following the supplied mounting instructions for the chosen type.

Usage recommendations

For longer periods of sitting, combine correct seat height and posture with regular micro-breaks and position the chair so your work surface is at elbow height. Clean synthetic leather with a damp cloth and mild detergent; avoid abrasive cleaners.
