Since the early noughties, various office equipment companies attempted to curb the negative sedentary effects of office related work by improving the design of the standard office chair. The result was a central tilting point. This mechanism is what allows us to refer to dynamic or active seating. Here's what you need to know about this phenomenon:
In chairs with a central tilting point, the backrest and sitting pan are fixed to the desired settings but the tilting point pivots according to your movement. According to the HAG In-Balance principle, it's easy to tilt backwards or forwards using your legs. This stimulates muscle activation of the legs and increases ankle movement. Two factors that are often lacking while using a traditional chair. A result of the added muscle activity is higher energy expenditure and less sedentary time.
