Arcos draws viewers’ first glances to its round, openwork central base. The idea and design for it hark back to Koni Ochsner (1933–1995). But in the 1980s it was still impossible to construct it in a compelling manner, at reasonable cost and with sturdiness in wood or cast iron. Today, it is possible. And in Arcos, Röthlisberger now presents this unique, concave-shaped base with its see-through openings. It allows lines of sight through it from every direction and neither obscures beautiful parquet nor a valuable carpet.
