RH Activ Chair
The industrial chair that follows your movements, always keeping the support at your back. This is an ideal chair for back pain sufferers or for those sitting for long periods.
Thanks to its simplicity and ergonomic design, RH Activ is ideally suited to most work environments, such as laboratories and industrial workplaces, where extra support is needed.
RH Activ 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.
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.

The RH Activ is suitable for both desk height and high bench work.
An ideal chair for reception and counter work.
It has a seat height range from 350mm to 810mm, depending on the gas stem chosen and has a full range of accessories
We recommend black vinyl cover material for most laboratory and industrial applications.
