Four open cubes and two full-width drawers form a versatile five-tier storage system in this 51-inch freestanding bookshelf that supports a combined 200 lbs. Each 13 x 12.5 x 13 in cube fits standard storage bins, and smooth-slide drawers with convenient handles keep personal items concealed below. Two anti-toppling kits anchor the unit securely to the wall, while the clean gray finish and screw hole stickers create a streamlined modern appearance.
