A drum of drawers is a strange object to build. Every drawer front has to curve on the same radius, every drawer box has to be jointed into a carcass that has no flat sides, and the drawer has to run straight in and out of a cylinder - which means the opening it passes through is a curved slot, tight at the edges and generous in the middle if the geometry is even slightly off.
Then there is the support problem. A cylinder standing on a narrower circular foot is inherently a balancing act: all the weight of the drum and its contents funnels down through the waist, and there are no corner posts to help.
That is what the acanthus scroll brackets are for. They start at the top of the drum, sweep down its outside and turn inward under the base, so they pick load up high and carry it around the waist into the spread of the foot. Cut them off and the vanity would still stand, but the drum would be relying entirely on its own short stem.
Our carvers shape those brackets from solid stock with the grain running along the sweep, because the curl at the bottom is where the load turns, and a bracket with cross-grain at that point would be decoration only. Here it is doing a job.
