How to use

Adjust the seat height so your feet rest flat on the floor and your knees form approximately a 90° angle. Use the synchro-tilt control to set the desired recline tension and angle; this coordinates backrest and seat movement for continuous support. Fine-tune lumbar support and any additional adjustable elements to fit your posture. Lock the mechanism if a fixed position is needed during focused tasks.

Usage recommendations

For best ergonomic effect, alternate between upright and slightly reclined positions during long sessions, take regular short breaks to stand and stretch, and adjust height and tilt every time a different user occupies the chair.
