Over Silhouette Verstelbare Stoel
Silhouette is een verstelbare stoel die door de herconfiguratie van zijn primaire elementen kan worden omgevormd tussen een fauteuil, loungestoel en chaise longue. In plaats van te vertrouwen op zichtbare mechanismen of verborgen onderdelen onder de bekleding, transformeert hij door de rollen van dezelfde zichtbare componenten die de stoel in elke stand definiëren opnieuw toe te wijzen. Met zijn strakke, sculpturale vorm en heldere structurele expressie biedt Silhouette een eigentijds alternatief voor conventioneel verstelbaar meubilair.

- Unieke Eigenschappen
- Silhouette is a transformable chair that shifts between an armchair, lounge chair and chaise lounge. Its defining feature is that the structure itself performs the transformation. In the chaise, the suspended headrest and legrest rotate to become load-bearing supports in the armchair, and vice versa. The chair changes function through structural reconfiguration rather than added mechanisms, and in each state the form reads as complete and resolved.
- Afmetingen & Verpakking
- Approx. 545 mm x 900 mm x 860 mm (armchair configuration) and 545 mm x 1400 mm x 780 mm (chaise lounge configuration).
Materials: Baltic birch plywood; steel sheet metal; steel rods; aluminum tubing; custom mechanical locking components; rubber gaskets; black powder-coated steel washers and elongated hex nuts; and leather-upholstered cushions.
Finished with a true black stain and clear polyurethane coating.
All moving connections are metal to metal, with no glue or permanent bonds between joints, allowing the chair to be fully disassembled, repaired, and reassembled without degrading the wood elements. - Tags

- Productietechnologie
- Developed through multiple full-scale prototypes, the geometry, proportions, and biomechanics were refined so that each configuration provides appropriate seat depth, height, and support, rather than functioning as a compromise between positions. After extensive hand drawings and scale models, a precise digital twin was developed before fabrication. The chair’s wood components were laser-cut, hand-routed, sanded, and stained, while custom sheet-metal components and steel rods were cut, manually threaded, welded and finished by hand.
- Ontwerpuitdaging
- Three main challenges defined the project. Conceptually, the chair had to function and appear resolved in multiple configurations while allowing elements such as the headrest and legrest to shift structural roles. Mechanically, suspended components required the development of a concealed locking system capable of resisting human load without visible hardware or auxiliary mechanisms. Fabrication demanded precise tolerances, extensive prototyping and iterative refinement to reconcile structural performance with formal clarity.
- Onderzoek
- This project is an experimental study on adaptable seating. The objective was to create a single chair that can be transformed to support multiple postures without relying on exposed mechanisms or hiding them beneath upholstery. The methodology combined precedent analysis, including measuring and cataloguing existing chairs and chaise lounges, with hand drawing, digital and physical modeling, and full-scale prototyping. Peers participated in use tests of successive prototypes to analyse and help improve comfort, balance and proportion. The research demonstrates that adaptability in furniture can be achieved without compromising structural clarity or formal integrity, expanding the possibilities for how seating is conceived and produced.
- Inspiratie
- Silhouette emerged from a long-standing interest in transformation in furniture: how an object might adapt to different ways of sitting without compromising formal clarity. It was inspired by the tension between movement and structure, and by the question of whether transformation could emerge from the form itself rather than from added mechanisms. Formally, it draws from the disciplined geometries and material restraint of modernist design while pursuing a distinctly contemporary expression.
- Projectduur
- The project was conceived at the Yale School of Architecture in New Haven, Connecticut, USA. Designed and fabricated entirely in the school’s wood and metal shops, the chair was completed in June 2024 following a four-month independent design-and-build process.
- Werkproces
- The chair transforms through a fluid rotation of its headrest and legrest: when shifting from chaise lounge to armchair, the headrest becomes the rear legs and the legrest the front legs. Concealed locking mechanisms within the base guide and secure each movement, allowing each position to be locked or released smoothly as needed. Adjustable armrests and an infinitely variable backrest support natural transitions in posture, from reclined to upright, with minimal effort and no external tools.
