Abstract: A container for securing objects in a moving vehicle comprises a bottom panel and a sidewall attached to and extending upwardly from the bottom panel to form a box-like structure forming a first container portion. The sidewall may be foldably attached to the bottom panel such that the container may be collapsed down so that it is more compact for easy storage. The sidewall may be comprised of a plurality of walls each attached to the bottom panel or alternatively, the sidewall may be formed by a single, integral structure attached to the bottom panel. The sidewall may be collapsible such that the sidewall may be folded or crumpled down relatively flat over the bottom panel. The container includes an adjustable divider disposed in the container which partitions the interior of the container. A variety of other accessories, such as drink holders, shelves, tables, and pockets may also be disposed in, or on, the container to conveniently hold objects in a moving vehicle.
