Yksi Chair is an armchair in typical Scandinavian design conceived by the Dane Jakob Thau and the Finn Sami Kallio. The chair frame is made of solid wood, a choice of material that makes the chair sturdy and stable. Choose between a black lacquered, lacquered oak and oiled oak finish. The chair’s design is modern yet classic. This makes the Yksi Chair an old-fashioned furniture that is suitable for both private homes and restaurants and cafés.

In addition to this chair, the Yksi furniture series also includes a similar chair with a clear seat and a bar stool in various finishes. The name of the series, Yksi, means "one" in Finnish and is a link to the designer duo's desire to combine several elements into one unit. The Yksi Chair also has chair legs that look like an upside-down Y.
