Key specifications

• Ergonomic high-back design with neck and lumbar support
• Height-adjustable gas lift mechanism
• Contoured seat padding for pressure relief
• Durable frame and reinforced construction for daily use
• Black and red upholstery with practical finishing

How to use

Adjust the seat height with the gas lift lever so your feet rest flat on the floor and your knees form approximately a 90-degree angle. Position the backrest and any included cushions to support the natural curve of your lower back. Use the armrests, if adjustable, to relieve shoulder tension and maintain relaxed shoulders while typing or gaming. Regularly change posture and take breaks to avoid static loading during extended sessions.

Usage recommendations

For best results, combine correct seat height and lumbar positioning with short movement breaks every 45–60 minutes. Keep the chair clean by wiping upholstery with a damp cloth and avoid exposing it to direct sunlight for prolonged periods to preserve color and material integrity.
