Key specifications

How to use

Adjust the seat height so your feet rest flat on the floor and your knees form approximately a right angle. Sit back against the chair’s backrest to use lumbar support effectively and use the swivel and casters to reach work surfaces without twisting your torso. If armrests are present, position them so your forearms rest comfortably while typing or writing. Regularly change posture and take short movement breaks to reduce static load during long work periods.

Recommendations

Periodically check caster condition and tighten fasteners if any loosen over time. Clean fabric upholstery with a soft brush or vacuum and treat occasional stains with a cloth dampened in mild detergent solution; avoid harsh chemicals. For optimal ergonomic benefit, combine the chair with an adjustable desk and monitor positioned at eye level.
