Made from heavy-duty commercial grade powder-coated steel, the shelving unit assembles without any tools and folds/unfolds within seconds. Each of the five shelves support up to 250 lbs. each (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). Pewter color. Folded 61 3/4" H x 3 1/2" W x 21" D; deployed 60" H x 36" W x 21" D.
