How to use

Adjust seat height so your feet rest flat on the floor and knees form approximately a 90-degree angle. Position the lumbar support and headrest to maintain the natural curve of your lower spine and to support your neck. Set the armrests to a height and angle that allow your shoulders to remain relaxed while using a keyboard, mouse or controller. Use the tilt mechanism to change recline angle during breaks or concentrated tasks and lock it at a comfortable position for sustained activity. Roll the chair on hard floors or suitable carpeting using the casters and avoid dragging the base to prevent wear.

Usage recommendations

For best ergonomic effect, periodically change posture, take short standing breaks every 30–60 minutes, and perform simple stretches to reduce muscle fatigue. Clean the mesh and frame with a soft brush or damp cloth and inspect casters regularly to maintain smooth movement.
