Object or Details
Every piece ships flat and knocks down completely. Switch the view below.
Side Table / Stool
A compact two-tier form that doubles as a stool. Locks together with a simple rotation.
Coffee Table
A double-shelf silhouette where the aluminum planes read as thin, floating surfaces between four oak legs.
Lounge Chair
3 aluminum planes form the seat, back, and the connection point to an oak leg. The leg locks in with a combined twist and press action.
Low Bench
A solid oak slab rests on a folded aluminum frame, finished with a final manual bend at assembly.
A Material Dialogue
The identity of the collection rests on a deliberate dialogue between two materials, kept visible rather than resolved away. Every piece is made from just two: 5mm aluminum and solid oak. Toggle Plane / Grain above to shift the site to match.
Aluminum
Sanded aluminum sheet, finished with wax for a natural look that matures alongside the oak, in a muted, desaturated slate blue/gray. Sharp architectural lines, geometric rigidity, thin profiles.
Oak
Rich, warm oak wood. Organic permanence, texture, and structural mass grounding each piece.
Precision Mechanical Joinery
Toolless Assembly
Aluminum panels slip directly through precision-milled slots in the oak timber — no tools required.
No Adhesives
Rigid structural integrity comes purely from geometry, friction, and gravity — no screws, fasteners, or wood glue.
Honest Construction
Metal tabs are left visible where they punctuate the wood, turning the logic of the joint into a decorative, functional feature.
Flat-Pack & Circular
Surface
Every piece is made from just two materials: 5mm aluminum and solid oak.
Both are sanded to a low grit and finished with wax, so the aluminum ages and matures naturally alongside the oak over time.
