Foss Extension. One shape at a time.
For those who want to build on their Foss Starter Set — one object at a time.
For horizontal wall compositions. Magnet on the back.
An extra Dropi alongside your existing Trio. A Steinn that carries the line forward. Or a few objects in a different wood — a second voice in the same composition. Here you choose the shape, mounting depth, wood type, and finish for each object individually.
Two shapes
Dropi — the drop, 22 × 15 cm. The soft, flowing form that gave the Foss family its signature.
Steinn — the square, 16 × 16 cm. The resting point beside the drop; where the eye takes a breath.
Per object, you choose
Mounting depth: 1 cm or 3 cm. The 3 cm option lifts the object from the wall and creates a three-dimensional shadow play.
Wood type: Walnut or Oak.
Finish: Natural, ½ Gold, or ½ Silver.
Magnetic system — compose until it feels right
Every individual object comes with a complete mounting kit: wall plug, screw, magnet, and metal ring (already mounted on the back). One screw in the wall — and you can still rotate and shift the object until the composition sits just right.
Prefer composing vertically?
For custom Foss Cascade lines — shape after shape clicked vertically — choose Foss Cascade Extension. There you’ll find the same Dropi and Steinn with magnets on top and bottom, plus the Cascade shapes Kristall, Carré, and Sólar (the Dropi with gold leaf).
