Teachers, librarians, and book lovers - this rolling book cart is an absolute game-changer for organization and mobility! With a massive 352-pound weight capacity (110lbs per shelf plus 22lbs on the unilateral placement), this heavy-duty cart can handle serious loads without breaking a sweat. The V-shaped shelves are genius - they hold about 30% more books than flat shelves while preventing them from sliding off, and the wall-hugging design saves precious aisle space. You get 4 lockable 360-degree casters (2.6 inches each) that roll smoothly over carpets, hardwood, and thresholds, then lock securely when you need the cart to stay put. The accessories are so practical - 3 hooks for bags or supplies, 3 book stands for display, and that handy unilateral placement for extra storage. The ergonomic handle reduces wrist strain when moving it around, and all the accessories are positioned within easy reach. Made from heavy-duty carbon steel with rust-proof screws and bolted joints, this cart is built to last through years of daily use. The rubber-tipped wheels protect your floors from scratches, and reinforced levers on top and bottom ensure stability. At 48.4x31.5x14.2 inches with 11.8x26.8x8.3 inch shelves, it's the perfect size for classrooms, libraries, offices, or even home use. Whether you're organizing classroom supplies, sorting library returns, or creating a mobile reading nook at home, this cart delivers functionality and durability that's worth every penny.
