Adjust the seat height to position your feet flat on the floor and your thighs roughly parallel to the ground. Sit back so the ergonomic backrest and integrated headrest support your spine and neck. Use the fixed armrests to rest your forearms at approximately desk height. The Kniematic tilt mechanism allows slight reclining; lean back gently to engage the tilt and maintain movement while seated. Roll the chair on a suitable floor surface using the safety double casters.
Usage recommendations
For optimal ergonomic benefit, pair the chair with a desk adjusted to elbow height and take regular short breaks to stand and stretch. Use on hard or low-pile carpet; consider protective floor matting on soft carpets to ensure smooth rolling and protect the floor.
