Product Description and Application: RH Activ follows your slightest body movement – comfortably as well as ergonomically. The RH Activ’s unique movements, based on our 2PP™ philosophy of active sitting, encourage core muscle activity, essentially benefiting the user with increased alertness and wellbeing. Furthermore, the Activ’s simplicity and ease of use makes it the preferred product for most office set-ups, including desk sharing. RH Activ can also be specified as a clean-room or ESD chair, which opens up a myriad of possibilities for this truly unique product. RH Activ is a range of chairs that function equally well as work chairs or office chairs. The chair analysed in this declaration – RH Activ 220 – features a large backrest, medium seat, black aluminium footbase and no armrests.
