Low – or no – mobility during the workday is a huge health concern as many shift to computer-based work. Wilkhahn chairs ON and IN offer an innovation that makes the sitting experience more dynamic.
A recent study by German health insurance companies revealed an alarming fact: 2023 will see people sitting for over nine hours per workday, a metric that has increased by 1.5 hours in the past seven years and has disastrous health consequences. This is the reality that motivated office furniture manufacturer Wilkhahn to work with health and sports professionals in developing Trimension, an innovative mechanism that offers three-dimensional, synchronously supported dynamic sitting on the brand’s classic ON and IN chairs.
What movement does Trimension allow, you might ask? Backwards, forwards, sideways: the adjustment mechanism supports two-dimensional bending and stretching of the torso and lateral hip movements – the latter of which is especially important for activating our skeletons and muscles and squashing back pain. The Trimension kinematics are specifically targeted at mirroring the ‘fluid motion of walking without causing fatigue,’ says Wilkhahn’s design team.
Celebrating its upcoming 15th anniversary, Wilkhahn's ON chair (cover, top and middle) supports intuitive and dynamic sitting. IN, a newer design (bottom), also is highly ergonomic, with a sporty appearance.
ON is further characterized by independently moving arms, a flexframe, slim shell, elastic backrest frame and a Fiberflex backrest covering. It accommodates a diversity of posture changes: each shift in weight is matched by parallel movements of the chair. Even ON’s pivot points correspond to knee and hip joints. The IN chair is a younger design, but with the same ergonomic attributes and optimal support. It has a sporty appearance and a unified twistable seat and stable backrest frame.
Next year happens to mark ON’s 15th anniversary. To celebrate the milestone, Wilkhahn has released the highly linear ON and sporty IN in fresh white models, symbolizing a sort of rebirth, and continual progress toward ‘bright, open and clear’ – but most importantly, healthy – work environments.
