1. A chair comprising:
a base; and
a seat coupled to the base, the seat including:
a pair of seat supports extending from the base, each of the seat supports configured to independently exhibit a first bending stiffness when bent to a stop point, and a first component is disposed apart from a second component when the pair of seat supports exhibit the first bending stiffness and until bent to the stop point, and exhibit a second bending stiffness when bent beyond the stop point, the second bending stiffness being greater than the first bending stiffness, and the first component contacts the second component when the pair of seat supports exhibit the second bending stiffness and when bent beyond the stop point; and
a seat support surface coupled to the pair of seat supports.
