Abstract
A hinge mechanism and mattress for use with a child containment device. A first mattress panel is pivotally coupled to a second mattress panel by a hinge mechanism, and is thereby convertible between an expanded configuration and a collapsed configuration. The hinge mechanism defines a limit point beyond which pivotal motion is prevented in at least one direction.
