The Amphi pieces of different heights form a scenic, auditorium-style arrangement of seating in the space according to need. The height and depth dimensioning of Amphi follows that of the Kivikko seats so they work well together.

The surplus material generated by the waste and cut-off pieces of foam plastic products is used as the raw material for Amphi. The waste generated in the manufacture is also returned back to the manufacturing process as raw material. The dense, soft material improves the acoustics of the space.
