Human life constantly shifts between focus and rest. DAY 2 NIGHT embodies this duality in a single adaptive chair, enabling a transition from day to night through a deliberate change in orientation and posture.

A continuous structure lets the user move intuitively between positions. Rather than relying on complex mechanisms, the chair responds directly to the body, redefining it as both a functional tool and a space for recovery.

In Work Mode, the chair provides stable ergonomic support for focused activity. To enter Lounge Mode, the user reorients the chair and reclines, actively shifting posture, balance, and spatial experience. This transition is not automatic, but intentional—transforming the act of sitting into a conscious movement between states.

The cantilevered frame ensures both flexibility and structural stability, while eco-conscious materials enhance comfort and tactile quality. This integration creates a clear and intuitive relationship between the user and the object.

DAY 2 NIGHT defines a continuous interface between action and rest.
