With five shelves in a narrow 28 by 13 inch footprint, this foldable rack is built for spots where floor space is tight but you still need height for storage. It unfolds and locks together in about a minute with no separate assembly step, just snap on the top panel and load it up. Five swivel wheels, two with brakes, roll smoothly across tile, cement, or epoxy floors and support up to 200 pounds in caster mode, with 360-degree rotation for easy repositioning. Switch to the four detachable support feet and the frame holds a static load of up to 750 pounds, with each layer rated for 190 pounds, while a crossbar keeps it from racking under a full load. When not in use, the shelf folds down to a slim profile for storage in a closet or car trunk. Four J-hooks give extra spots to hang tools, bags, or cords. Standing 66 inches tall, it works well in a pantry or garage.
