The objective technical task of the present invention is therefore to provide a piece of furniture which is improved compared to the prior art, as well as a method in which the disadvantages of the prior art are at least partially eliminated, and which are characterized in particular by convenient operation, a flexible adjustment option

and/or user-friendly assembly.

This problem is solved by the features of claim 1.

It is therefore provided according to the invention that the at least

an electric drive device is mounted on the carrier.

This makes it possible for the at least one electric drive device - for example, as an add-on to existing furniture - to be user-friendly, for example, in the front area of a receiving shaft, to be installed, retrofitted, maintained, or adjusted. Disassembly of the at least one door assembly or the receiving shaft to expose the at least one electric drive device

is generally not required.

The receiving shaft can, for example, be accessed through an external space on the side of the furniture body or through an internal space within

of the furniture body

In addition, there is the positive feature that, in contrast to electrical drive devices arranged at the rear in the receiving shaft, a coupling of the at least one electrical drive device with the at least one

Door arrangement is favored. For example, the at least

An electric drive device can be connected to a coupling gear for a pivoting movement of a revolving door. For example, the at least one electric drive device can interact with a rack in order to move a folding sliding door translationally along the receiving shaft. In general, the at least one electric drive device can be provided for both a closing and an opening process, wherein the at least one electric drive device is preferably provided at least for an opening process along a furniture front and/or a
