Product Story

Portone Chair is the union of style and comfort.

The pliable frame harmonizes with your movement as the lumbar support comfortably contours the curves of your back that accommodates natural side-to-side movement.

A design born of Okamura’s fascination with ergonomics.

The supple lumbar support fortifies your body’s core, reinforcing a healthy posture. The lumbar support easily adjusts to match your physical requirement. To adjust, simply grasp the lower ridge of the lumbar support and push up or down.

1D, 3D and 4D adjustable arms easily adjust up and down. 4D adjustable arms also twist inward and outward and slide forward, backward, right and left.

Reclining tension can be adjusted by rotating the dial under the center of the seat. Turn clockwise to increase tension, or counterclockwise to reduce tension.
