1. A human support structure comprising:
at least one support configured to support at least one part of a human body; a base;
a first motion transmitting assembly comprising first and second link members joined to each other for pivoting movement around a first shared axis and defining a first unit;
the first link member joined to a component for pivoting movement around a first axis,
the second link member joined to a component for pivoting movement around a second axis;
a second motion transmitting assembly comprising third and fourth link members joined to each other for pivoting movement around a second shared axis and defining a second unit,
the third link member joined to a component for pivoting movement around a third axis,
the fourth link member joined to a component for pivoting movement around a fourth axis,
the first and second motion transmitting assemblies cooperating between at least one of: a) each other; b) at least two of the at least one support; and c) the base and at least one support to guide relative movement between the at least one support and the base,
the human support structure configured so that the first and second units are selectively and controllably relatively repositionable, while maintaining a relative position of: a) the first and second link members on the first unit; and b) the third and fourth link members on the second unit, to change how relative movement between the at least one support and base is guided,
wherein at least one of: a) the first shared axis; b) the first axis; and c) the second axis is non-parallel to another of: a) the first shared axis; b) the first axis; and c) the second axis,
wherein the first shared axis and the first axis have a fixed relationship.
