Overview

Designed for comfort and ease, this versatile work and lounge chair provides functional support for professional work in the office while stimulating a flexible mindset.

Gently enveloping the body, its design integrates a synchro-tilt mechanism—essential for task chairs—to ensure comfort during long work hours. The backrest curves seamlessly into the armrests, supporting a broad variety of sitting positions and encouraging relaxed, natural conversation in the workspace.

Available in high or low versions and a wide range of colors and materials, BIWA’s versatility adapts to diverse settings from desk work to meeting rooms, lounges to conference environments.

Design ConceptbyKohei Wada

BIWA aspires to resonate with human emotions through a timeless design that transcends typical task chair aesthetics.

More than ever, offices are evolving into vibrant spaces where ideas and collaboration generate new value. It follows that furniture design should also evolve beyond the conventional notion of “office furniture.”

The soft silhouette, reminiscent of a lounge chair, features a separate shoulder rest that appears to float in space, creating a magical focal point. The embracing form draws inspiration from the shape of the traditional Japanese instrument biwa, from which it takes its name, and Japan’s Lake Biwa, where the chair is produced.
