designer Hans Coray used the motif for his 
aluminum chair “Landi” designed for the 1939 
Swiss National Exhibition in Zürich. Circular 
Perforation was also offered in the seat and 
backrest, which was molded from one sheet 
of aluminum, since this allowed rainwater to 
flow through it better when the chair was used 
outdoors. In the late 1950s, it was the architect 
Roland Rainer, who designed the so-called 
“Stadthallensessel,” as part of the furnishings 
of his civic center in Vienna. The molded ply 
wood seat and backrest of this chair is char- 
acterized by the hole pattem in the backrest. 
Like Coray’s “Landi," which until now has been 
re-introduced in several new editions, Rainer's 
“Stadthallensessel” was re-launched at the in- 
stigation of the architect Gregor Eichinger in 
the mid-1 990s and temporarily put into pro- 
duction with slight structural improvements.
