How to use

Adjust the chair height so your thighs are parallel to the floor and your feet rest flat on the ground or a footrest. Use the backrest adjustment to find a supported posture for the lumbar region and lock the backrest angle when you find a comfortable position. Activate the rocker mechanism for gentle rocking when needed and set the 2D armrests to match your desk height to keep shoulders relaxed. Attach the head and lumbar cushions at positions that support your natural spinal curvature; remove the cushion covers for washing at 30°C when necessary.

Recommendations

For ergonomic use, combine correct seat height and backrest angle with short movement breaks every 45–60 minutes. Use the chair’s adjustment options to tailor support for your body and work style; the breathable fabric and cold foam padding help maintain comfort during extended gaming or office tasks.
