This stationary unit features no back and cut out side openings to provide maximum supervision of children making it the perfect storage option for Montessori spaces and areas with young ones! This open view also makes it easy for kids to see and pick items off the shelves. Two adjustable shelves accommodate toys and supplies of all shapes and sizes while the top, featuring a raised back and sides, is designed to help contain items and prevent them from falling on the floor. The top and each of the shelves also have metal stiffeners attached to prevent bowing and add strength.
