ABSTRACT:
An article of furniture includes a drive device for moving a movable furniture part. The drive device includes an electric drive unit and a coupling device for at least temporarily transmitting a force of the electric drive unit to the movable furniture part, and the coupling device has a drive and a drive output. Operating between the drive and the drive output are coupling elements by which, in a first operating position, a clamping connection between the drive and the drive output and thus coupling between the drive and the drive output can be produced, and, in a second operating position, the coupling elements are movable into a position in which the drive and the drive output are not coupled.
