Mounted flush to the wall, this 4-tier industrial pipe shelf turns unused vertical space into a striking wall bookshelf for cookbooks, plants, and collectibles. Thickened engineered-wood boards ride on a matte metal pipe frame, giving each 25.5-inch shelf a 45 lbs capacity and the whole unit 180 lbs in total. Twelve inches of clearance between tiers fits tall bottles and framed photos, and the included expansion screws anchor it securely.
