An interior designer has a dilemma. She has to move an amazingly heavy armchair which is up against a wall. The chair needs to be sitting so it is exactly beside its starting position and facing the same way.

If the only possible movement is to rotate the chair on any of its corners, how can the chair be moved to its new position?

(In reply to solution by Charlie)

If the chair is firmly up against the wall, then this method is impossible, because the chair will rub into the wall on the first rotation!! Try actually experimenting with it... its true!
