OUI Armchair

Close

O — the seat, U — the backrest, I — the legs: OUI — the armchair.

Based on three elemental forms, the chair follows a clear structural logic. Each element remains legible while together forming a balanced and comfortable object.

For the event space of our friend and Michelin-starred chef Andreas Tuftensammer, we designed this armchair to combine generous comfort with a distinct, refined silhouette. Rooted in a close collaboration with our trusted manufacturing partners, the piece evolved through a careful process of iteration and detail refinement.

Soft upholstery meets a precise wooden frame, creating a quiet contrast between tactility and structure. OUI expresses an approach to furniture that values clarity, proportion and the presence of natural materials.

Legs are made from solid oak with a natural oil finish. Upholstery fabrics are sourced from Dedar and Kvadrat.

Conceived to offer lasting comfort, the chair retains a distinct and memorable silhouette
