For most people, sitting in an office chair for eight to nine hours a day leads to a string of problems — from neck pain and back ache to a general feeling of discomfort. And no amount of height adjustments of the chair seem to help. Precisely why Humanscale, a Bengaluru-based office furniture maker, launched chairs without knobs and levers. Instead, these chairs read the weight of the user and instinctively provide the perfect recline — a truly ‘ergonomic’ offering that has been designed for improving comfort plus efficiency in the working environment.
