The Zagen office chair can help you correct your sitting posture. The backrest is equipped with an adjustable lumbar support function to help you adjust to the most suitable waist position, maintain the best sitting posture and relieve the pressure on the spine.



Zagen Series' headrests and back is upholstered with Breathable Mesh, providing elastic back support that allows body heat and humidity to be released effectively while seated, keeping you fresh at all times.

Zagen Series' Breathable Seat base padded with high-density soft foam allows long sessions of working even in hot and humid weather.


The S-shaped design of the backrest, paired with the included Lumbar Support Pillow, accommodates to the natural curve of the spine preventing any unwanted spine compression.
