Modular by design, this stackable cube storage organizer builds from a single 13.5-inch cube into a custom small bookshelf tower up to four units tall. High-strength engineered wood boards hold 55 lbs per cube, ready for novels, vinyl records, or display pieces. Screw hole covers and protective foot pads keep the finish polished on every side, so the open cube works equally well against a wall, under a window, or as a freestanding room divider.
