Office chair ActiveJet YK7406-1 — padded seat and backrest, black, backrest 49×50 cm, seat width 49 cm

ActiveJet YK7406-1 is a black padded office chair designed for everyday desk use in offices, home workspaces and study areas. The chair combines an ergonomic backrest profile and a wide leather-covered seat to provide stable support and comfort during long hours of work or study. A metal five-star base with polyurethane castors and a 360° swivel allow smooth movement and easy access around the workstation.

Advantages

The chair’s ergonomic backrest includes a lower roller that follows the natural curvature of the spine to help maintain correct posture. A generous seat (49 × 47 cm) and a large backrest (49 × 50 cm) deliver stable support for most users, while soft padded armrests reduce strain on shoulders and arms. Height adjustment via a pneumatic gas lift and a butterfly tilt mechanism let you set a comfortable seating position. Durable metal frame and polyurethane wheels ensure long‑term durability and smooth mobility on typical indoor floors.

Suitable for

• Office work and meetings
• Remote work and home offices
• Student study and long reading sessions
• General desk tasks and computer use

Key specifications

• Seat width: 49 cm; seat depth approximately 47 cm
• Backrest dimensions: approximately 49 × 50 cm
• Upholstery: black PU leather (padded seat, backrest and armrests)
• Base: five-star metal base with polyurethane castors
• Swivel: 360° rotation
• Height adjustment: pneumatic gas lift (class 2)
• Tilt mechanism: butterfly tilt for backrest angle adjustment

How to use

Adjust the seat height with the pneumatic gas lift so that your feet rest flat on the floor and your knees form roughly a right angle. Use the butterfly tilt mechanism to set the preferred backrest angle for comfortable support of the lumbar area. Sit so that the lower roller of the backrest supports the natural curve of your lower back and rest your forearms on the padded armrests while typing or using a mouse. The 360° swivel and polyurethane castors allow you to move around the workspace without standing up.

Usage recommendations

Place the chair on a clean, flat indoor surface and check castors periodically for debris. For longevity, avoid exposure to direct sunlight and clean the PU leather with a damp cloth and mild soap when needed. Regularly check and tighten fastenings and follow the manufacturer’s instructions when adjusting mechanisms.
