How to use

Adjust seat height so your feet rest flat on the floor and knees form approximately a 90° angle. Set the lumbar support height and depth to match the natural curvature of your lower spine. Position the headrest to support the base of the skull without forcing the head forward. Change armrest positions to keep shoulders relaxed and forearms level with the desk. Use the chair’s adjustments as needed throughout the day to maintain comfort and correct posture.

Usage recommendations

For prolonged sitting, combine correct chair adjustment with regular breaks and light stretching. If multiple users share the chair, recheck and readjust lumbar, headrest and armrest settings when switching users to maintain ergonomic support.
