Our carts offer superior organizational options for storing and transporting large quantities of books. These Book Carts feature an ergonomic handle and spring platform that is designed to reduce strain while loading, transporting, or unloading the cart. The spring platform lifts contents of the cart while unloading, reducing the need to bend over. Ergonomic Book Carts are ideal for educational facilities, libraries, community centers, or any other facility that handles large amounts of books. At grade schools, middle schools, high schools, community colleges, colleges and universities, our carts are used in libraries and other classroom settings. These carts offer the most flexibility since they will fit through hallways, can be used inside or outside, and will fit through an average doorway. The casters are non-marking which erases worry of ruining floors. Its durable, double-wall blow-molded polyethylene body can withstand day-to-day punishment, making it perfect for almost any application. The cart is rust proof, making cleaning a cinch. The black ergonomic netting on both sides can be detached for easier access to contents. The unit includes Heavy-Duty 4" roll-quiet casters; two swivel and two rigid. In addition, the rugged steel frame includes tow bars if multiple carts need to be trained together.
