The Okamura Portone combines function and design to give rise to a truly comfortable task chair.

 
 
 

Sit, and the chair moves pliably to firmly support your hips. Portone was born of Okamura's obsession with studying the human body.


The Portone chair has a small frame contoured to the beautiful curves of the chair back. Its minimalist, square form offers a sense of simplicity and refinement and suits a diverse range of office settings.
