This 4-tier storage shelving unit brings organized, freestanding storage to a garage, basement, pantry, kitchen, or laundry room. Constructed from durable polypropylene, the unit features a waterproof, anti-crack, and anti-slip surface with reinforced crossbars and side supports for stable, long-lasting performance. The assembled unit measures 24 x 12.5 x 37 inches and weighs 7 pounds, with each of the four shelves holding up to 100 pounds for a total weight capacity of 300 pounds. A 14.5 inch clearance between shelves allows room for bins, totes, and boxes of varying sizes. Two anti-toppling devices help anchor the unit for added stability, and the modular design lets shelves be combined or separated to fit the available space. Assembly is tool-free: support columns insert, shelves connect, and four caps finish the top layer. The package includes one shelving unit and an instruction sheet, and the surface wipes clean for easy upkeep.
