Just as the name implies, rolling shelf carts combine the benefits of shelf storage with that of a cart. Whatever the teacher or students need when classrooms move outside can be easily transported on this heavy-duty cart. Many styles have extended sides on each shelf to prevent items from falling off when the cart is moving. If technology will be used, select a rolling shelf cart with a laptop tray or cabinet for storage. All have locking swivel casters for easy mobility outdoors.
