This three-tier rolling book cart keeps books, binders, and office supplies organized and easy to move between rooms. Built from carbon steel with a rust-resistant coating, it measures 30.3 x 15 x 48 inches, and each 13.7-inch-high shelf supports 110 pounds, for a combined capacity of 330 pounds -- enough for a full load of hardcover books or heavy equipment. Side compartments on each shelf hold A4 folders or tablets so nothing slides off while you push it around. Four TPR silent swivel casters roll quietly across wood or tile, and two lock in place to hold the cart steady while loading or unloading. Assembly is simple with pre-drilled holes, an included guide, and extra screws. The white steel frame suits libraries, classrooms, offices, and home bedrooms, making restocking shelves or moving documents easy and quiet.
