Key specifications

• Ergonomic seat and backrest shape for prolonged sitting support

• Reclining backrest with multiple angle settings for rest and focus
• 360° swivel base for easy rotation and mobility
• Armrests for forearm support during extended use

How to use

Adjust the seat height so your feet rest flat on the floor and your knees form approximately a right angle relative to the seat. Use the reclining lever to set the backrest at a comfortable angle for either focused work or a relaxed position; lock the backrest if your model provides a locking mechanism. Position the chair close to your desk so forearms rest comfortably on the armrests while typing or using a controller. Rotate on the swivel base to change orientation without standing.

Usage recommendations

For prolonged sessions, vary posture periodically: switch between upright and slightly reclined positions, take short breaks to stand and stretch, and adjust seat height and armrests to keep wrists and shoulders relaxed.
