Fifty-five pounds per shelf on a 12 lb frame is an unusual ratio, and the mesh wire is why - open steel grid rather than solid panels, reinforced by a bar through the middle. It also means water and dust do not collect, which matters beside a sink. Three lower shelves take a microwave, an oven and kitchenware; the bar across the top accepts hooks for cups and cloths. The unit measures 23.5 x 13.5 x 53.5 in in white-finished iron. Assembly is required and the parts arrive in one carton. Two other finishes, gray and black, are offered on the same frame.
