Abstract: An adapter is removably attached with engagement means, such as screws, to an object such as the leg of a piece of furniture, such as a table or chair. The adapter attaches to the furniture leg in such a manner that the screws do not mar the furniture, nor do they require a groove, indentation or recess on the furniture leg for attachment thereto. The adapter is configured so that the distance from the leg to the ground is less than the diameter of the wheel mounted on the adapter. The adapter is also configured so that the leg is laterally displaced from the wheel. The wheel is also swingably retractable so that the furniture can be made stationary without having to remove the adapter.
