A first fastener 19 is configured to be releasably connected to the front fastening device 12a, and a second fastener 19 is configured to be releasably connected to the rear fastening device 12b of the furniture drive 6, whereby the carrier 7 and the mounting portion 14 can be tensioned relative to one another within the recess 11 of the sidewall 2a.

(13) FIG. 2 shows the item of furniture 1 with the furniture carcass 2 in a perspective view, in which the furniture drive 6 is received, for the most part, within the sidewall 2a of the furniture carcass 2. In a mounted condition, the furniture drive 6 can be covered on at least one side, preferably on both sides, by a top layer of the sidewall 2a, whereby a very compact and aesthetically unobtrusive arrangement of the furniture drive 6 can be provided. The recess 11 of the sidewall 2a of the furniture carcass 2 can either be configured as a blind hole or as a through hole.

(14) A plurality of fasteners 24 are provided on the actuating arm 8, the fasteners 24 being configured to be fixed to the rear side of the movable furniture part 3. The movable furniture part 3 is pivotally mounted to the underside of the furniture panel 4 by conventional furniture hinges and can be moved relative to the furniture carcass 2 between a vertical closed position and an elevated open position by the actuating arm 8 of the furniture drive 6. The actuating arm 8 of the furniture drive 6 is pivotally supported between a fully closed position and a fully open position, and the actuating arm 8, in the fully closed position, is at least partially, preferably substantially entirely, received within the sidewall 2a of the furniture carcass 2.

(15) In this connection, it can be advantageous when at least one fastener 24 of the actuating arm 8, as commonly known, is releasably lockable to a fitting body (not shown) to be fixed to the movable furniture part 3. When the actuating arm 8 of the furniture drive 6 is at least partially countersunk within the recess 11 of the sidewall 2a, it is advantageous when the actuating arm 8 is releasably locked in its closed position. Then, the fitting body of the movable furniture part 3, in the closed position of the actuating arm 8, is automatically lockable with the actuating arm 8 by manually pressing the movable furniture part 3 in a direction of the front face 17a of the sidewall 2a of the furniture carcass 2.
