Twenty inches between shelves is exceptional on a narrow bookcase, and it means this 18-in wide tower takes tall art books and stacked boxes that a conventional 12-in gap would not. A drawer 13 x 11 x 9 in inside sits at the base for closed storage, and the lowest shelf clears the floor by 4.5 in. Shelves hold 45 lbs each and the drawer 22 lbs. The frame stands 62.5 in on an 18 x 14 in footprint at 41 lbs, in white engineered wood with a gold-finish metal frame.
