The Kreuzschwinger is a new type of sitting and reclining furniture, which adapts automatically to changing body posture and can swing forward and backward without mechanisms. This design sensation received many international rewards and is on display in many museums. This modern classic was plagiarized in part or entirely 101 times. The legal chapters comprise a fascinating and instructive series of plagiarism-whodunits until the Kreuzschwinger became the ninth piece of seating furniture in history to be awarded the far-reaching copyright protection for applied art.
