Thirteen inches between shelves across a 67-in frame means every one of the five tiers takes a standing hardback, not just the bottom two. Shelves measure 22.5 x 9 in and hold 45 lbs each. The 9.5-in depth keeps the unit tight to a wall in a hallway or a study. Dual anti-tipping kits secure it, which matters at this height. Engineered wood and MDF bring the weight to 34.5 lbs across a 24-in width. Rustic brown suits a room with warm flooring; assembly is required from the enclosed instructions.
