Active Work Chair from KOS IrelandThe Activ Chair 22 follows all your movements, so that you sit flexibly and actively, while your lower back is always supported – which is both comfortable and ergonomically correct. 

No need to make adjustments, the chair adjusts to you.

The secret is the Active Movement System (AMS) that creates a free-float, ergonomic pattern of movement that is unique to RH Activ. The position of the lever ensures ease of use while sitting in the chair.

The Active Movement System adapts to you from the moment you sit down. The movement of the backrest on free-float adapts to your body weight allowing for constant support which follows your body’s movements.
