A flush-mounted guiding arrangement adjustably mounts furniture parts that are extractably and insertably mounted inside a furniture carcass by means of a pair of extensible guides encompassing one respective guide rail. The sliding rail is longitudinally guided on the guide rail and can be placed in the lateral edge region on the bottom face of the extractable furniture part. An adjusting fixture grips the bottom of the furniture part that is to be mounted and in the forward end area of the sliding rail. The adjusting fixture has a mechanism for adjusting the position of a sliding rail relative to the extractable furniture part in the direction of at least one axis of a Cartesian coordinate system formed by three coordinate axes that run substantially perpendicular to each other.
