These are the foldaway shelves that hold a total of 600 lbs. and tuck into an unused corner to instantly create an organized storage space. Made from heavy-duty commercial grade powder-coated steel, the shelving unit assembles without any tools and folds/unfolds within seconds. Each of the four shelves support up to 150 lbs. (without wheels). When not in use, the unit folds flat for compact storage under a bed, behind a door, or in a crawlspace. It comes with four optional smooth-rolling casters for easy repositioning (adding wheels reduces weight capacity to 75 lbs. per shelf/300 lbs. total). Pewter color. Deployed 59" H x 29" W x 29" D. (44 lbs.)
