How to use

Adjust the seat height so your feet rest flat on the floor and your knees form approximately a right angle. Set the lumbar and headrest positions to support the natural curve of your spine and avoid forward head posture. Adjust the armrests to a comfortable height that keeps your shoulders relaxed while using a keyboard, mouse, or controller. Use the castor wheels to reposition the chair smoothly; ensure the floor surface is compatible with rolling casters. Follow any included manufacturer instructions for assembling the chair and connecting or configuring the RGB lighting if applicable.

What to consider before purchase

• Confirm that your weight and height fall within the supported limits (up to 120 kg, up to 205 cm)
• Check seat and backrest colour and material to ensure it fits your comfort and room aesthetics
• Consider whether hard adjustable armrests meet your ergonomic preferences
• Ensure your space accommodates the chair footprint and allows free movement on castor wheels

Usage recommendations

For extended sessions, periodically change posture and perform short breaks every 45–60 minutes. Use lumbar and headrest adjustments to maintain a neutral spine position and set armrests to support relaxed shoulders; this will help reduce strain during prolonged gaming or work sessions.
