This 4-tier folding shelf sets up in about a minute, unfold the frame, snap on the top panel, and it's ready, no tools required. Built from Q235A carbon steel, it stands 60 inches tall with a 36 x 21 inch footprint and holds up to 190 pounds per shelf. Switch between five swivel casters (two with brakes) for rolling it across tiles, cement, or epoxy floors, or detach the wheels and use the support feet for a static load rating of 750 pounds; in caster mode it carries up to 200 pounds. Four J-hooks on the frame give you extra spots to hang tools, bags, or cords. When you don't need it, the whole unit folds down to just 4.7 inches thick, so it tucks behind a door, slides into a closet, or fits in a car trunk for use as a temporary shelf outdoors. At 18.74 pounds it's light enough to move and store on your own. Good for organizing a pantry, kitchen, garage, or basement where floor space is tight.
