Five tiers combine triple open shelves and a lower enclosed cabinet to organize books, decor and household items within a 23 x 12 x 70 in frame. Upper shelves measure 22 x 11 in with 13-in spacing, and each tier supports up to 44 lbs to hold heavier hardcovers or collectibles. A 3-position adjustable shelf in the cabinet, with 10.5 x 9.5 x 24 in inner compartments, can be removed to make room for taller objects, while the reversible lower shelf installs on either the left or right to suit your layout. Sliding doors on aluminum alloy rails let you reach stored items without needing extra clearance for door swing, and solid wood legs with protective foot pads help keep the unit stable and reduce floor scuffs.
