World’s First Sidestacker

Christian Flindt, a Danish designer, in 2005 won the Design Award at the Copenhagen International Furniture Fair for Parts of a Rainbow, the chairs that stack and store side by side.

Christian says of his design philosophy, "I am interested in communication between people.
I want to rethink furniture in a way that they will inspire people to make new connections."

This arrangement works too.  See more of Christian’s works at his website.
