Key specifications

• Upholstery: black woven fabric
• Ergonomic backrest with lumbar contour
• Seat padding: medium-firm foam for daily use
• Adjustments: pneumatic seat height adjustment, tilt mechanism
• Base: five-star base with smooth-rolling casters
• Armrests: fixed or adjustable depending on configuration

How to use

Sit with your back against the contoured backrest and adjust the seat height so your feet rest flat on the floor and your knees are at approximately a 90° angle. Use the pneumatic height lever to raise or lower the seat and engage the tilt mechanism to set the desired recline tension. Position the chair close to the desk to keep forearms supported while typing, and adjust armrests if present to align with the desk surface. Regularly change position and stand up periodically to reduce static load on the spine.

Usage recommendations

For prolonged daily use, combine correct seat height and backrest position with short movement breaks every 30–60 minutes. Use a chair mat on soft floors to preserve casters and ensure stable rolling. Clean the fabric periodically with a vacuum nozzle and a damp cloth; avoid aggressive chemicals to maintain upholstery condition.
