Abstract
A chamber may include a first barrier portion, a second barrier portion, a peripheral bond, an interior bond, and a fold. The first barrier portion defines a first surface of the chamber. The second barrier portion defines a second surface of the chamber, the first surface being opposite the second surface. The peripheral bond 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. The interior bond is spaced inward from the peripheral bond and joins the first barrier portion and the second barrier portion. Additionally, the fold is in the second barrier portion and extends away from the interior bond and through a majority of a thickness of the chamber.
