11. A chamber comprising:
a first barrier portion formed from a polymer material and defining a first surface of the chamber;
a second barrier portion formed from the polymer material and defining a second surface of the chamber, the first surface being opposite the second surface;
a peripheral bond that joins the first barrier portion and the second barrier portion to form an interior void within the chamber and seal a fluid within the interior void;
an elongate first interior bond that is spaced inward from the peripheral bond and joins the first barrier portion and the second barrier portion;
a first singular fold in the second barrier portion having a first portion of the second barrier portion and a second portion of the second barrier portion opposing one another and extending in a single direction away from a distal end of the first interior bond at a first angle;
an elongate second interior bond that is spaced inward from the peripheral bond and joins the first barrier portion and the second barrier portion; and
a second singular fold in the second barrier portion having a third portion of the second barrier portion and a fourth portion of the second barrier portion opposing one another and extending in a single direction away from a distal end of the second interior bond at a second angle, the second angle being substantially equal to the first angle.
