ON Task Chair

Unlike traditional chairs that restrict natural movement, ON encourages constant micro-movements that keep the body active and balanced. Two independently movable swing plates at the core of the mechanism mimic the function of thighs, hips, and knees. Even the smallest weight shifts are translated into movement, allowing the pelvis to rotate freely—essential for spinal stability and overall well-being.

This innovative approach provides a significantly greater and more natural range of motion for the pelvis and shoulders, stimulating metabolism, improving spinal elasticity, and enhancing muscle coordination without tiring the body. Backache is effectively prevented, while joints and muscles remain activated throughout the working day.

Excellent comfort is ensured by the combination of a torsionally flexible upholstered seat shell, an elastic back frame, and a breathable Fiberflex cover. With a wide range of models and configurations, ON delivers ergonomic performance, distinctive design, and functional versatility for every office environment.
