An adjustable attachable coaster that snaps on any beverage can, disposable coffee cup, and all sizes of soft drink cups. The coaster gives the beverage container a wide base with a no-slip bottom when attached. It is designed to sit on any surface including dashboards, passenger seats, car consoles, stuffed chairs, sofas, beds, waterbeds, picnic grass, and all boat deck surfaces. The user merely takes this coaster out of the glove box or other convenient storage area, sets it down on any surface, and then places the can, plasticware or disposable cup in the middle of the coaster and snaps the hook on the upper edge of the container. The hook is attached to an elastic shock cord. There is a downward pressure from the elastic shock cord and the bottom of the container is "locked" in the recess or other transverse surface below. The beverage container now becomes one with the no-slip base. The no-slip material on the bottom of the coaster simply works by the friction of the textured material that allows it to stick to most surfaces to a forty (40) degree tilt. The beverage with the attached coaster now has a very wide base with a lowered center of gravity. It is very difficult to knock it over and therefore the container is able to withstand sudden forces imparted to it, such as the shock of a sudden stop of the car or other vehicle. The user drinks with the coaster attached.
