One of the premium current furniture designers of all time, the Finnish creator Eero Aarnio is acknowledged all over the world for being a originator of fiberglass furniture. But of all of his works none would show to be as essential as his Ball Chair creation.

As its term mean, the Ball Chair is a lounge chair formed like a ball. The chair's body is created out of a hollow sphere finished from a fused fiberglass material of polymer and fine glass fibres. The chair's building made both lightweight and durable, and thanks to the fiberglass' structure it was also fireproof. The chair is fixed with a funnel- formed base at the foot, and for relieve the inner part is fixed with polyurethane cushions enclosed with brilliantly-colored fabric or leather. Early creation runs of the Ball Chair were also ntegrated with a bright red telephone at the side, although it is detached in present reproductions with some high-end models restoring it with more present services for instance iPod docks and liquid crystal display (LCD) screens.

The Ball Chair is completed by Aarnio's in 1963 and is accredited as the creation that jump-started his career. Ironically, Aarnio initially done the Ball Chair for himself, as his house had no big chair to speak of. A sample of the Ball chair was firstly done from plywood which in turn was apply in shaping the final cut from fiberglass in a procedure related to that used in the manufacture of gliders and light aircraft works. After considering the affirmative intuition from people that visited his house, Aarnio decided to display his design to the International Furniture Fair in Cologne, Germany. The chair became a first Ball Chair still continues in its place in Aarnio's home, though reproductions based on the chair's design are being constructed.
