A piece of furniture includes an upright post, a horizontal rail, and a fastening unit. The upright post is provided with a coupling base having a parallel pair of side walls and a connecting wall that interconnects the side walls and that inclines inwardly and downwardly such that side walls and the connecting wall cooperatively confine a vertical engaging groove which tapers downwardly. The horizontal rail includes an upper rail member and a lower rail member mounted on a bottom side of the upper rail member. The upper rail member is provided with a tongue unit which extends downwardly into the vertical engaging groove. The tongue unit has a parallel pair of flanges confined between the side walls and an inclining wall that interconnects the flanges and that is superimposed on the connecting wall. The lower rail member is provided with a support unit which includes a parallel pair of abutment walls and a vertical wall which interconnects the abutment walls. Each of the abutment walls has an inclining outer edge which abuts against the connecting wall. The upright post, the connecting wall, the inclining wall, and the vertical wall are formed with aligned fastener holes to permit extension of the fastening unit therethrough for fastening the horizontal rail to the upright post.
