Five open tiers share a wall mounted frame, so you gain vertical storage without using much floor space. Each 15.5 x 12 in shelf supports up to 33 lbs, giving you room to arrange books, plants or kitchen items securely. Dual anti-tipping kits fasten the metal structure to the wall to enhance stability, while adjustable foot pads help the frame sit level on uneven floors. A 7.5-in bottom clearance leaves open space so you can sweep or mop under the ladder shelf easily.
