Disclosed is a collapsible device which can provide at least partial containment for one or more objects, including a child or animal, and which can collapse or fold into a compact configuration in order to allow for improved portability of the collapsible device. In some implementations, the collapsible device can include a collapsible frame and at least one flexible material component that can be reversibly secured to the collapsible frame. In addition, some implementations can include a foldable base or at least one adaptable feature.
