A drive device for a movable furniture part includes an ejection force accumulator which can be tensioned, and an ejection element mechanically loaded by the ejection force accumulator and used to carry out an ejection movement of the moveable furniture part from a closed position into an open position. The ejection movement can be initiated by a compression movement of the movable furniture part into a compression position which is behind the closed position. The drive device also comprises a tensioning device for tensioning the ejection force accumulator with energy which can be emitted by the ejection movement. During the compression movement, at least 50% of the energy emitted by the ejection force accumulator during the ejection movement can be introduced into the ejection force accumulator by the tensioning device.
