Four storage shelves on a foldable frame create flexible space for tools, pantry items, or decor, while the 30 x 14 x 48 in unfolded size offers vertical storage without taking much floor area. The MDF shelves mount into slots along the powder-coated metal frame so you can choose from 10 positions with about 4.3 in between layers, adjusting the spacing for taller boxes or smaller jars. An anti-toppling device helps secure the unit to the wall, and the heavy-duty frame supports up to 180 lbs. Four universal wheels, including two lockable casters, let you roll the shelf between rooms or keep it firmly in place. When not in use, the 14 x 3 x 48 in folded size makes it easy to store against a wall or in a closet.
