Rolling drawers change how this organizer gets used. Each 19.5 by 14 by 11 inch bin rides on 4 casters, 2 of them lockable, so a child can pull one out to the living room rug and push it back at bedtime instead of carrying armfuls of toys. Above them sits a 39 by 8 inch upper shelf and an open compartment 10.5 inches deep for books and snacks, with 12 inches of height in the bottom bay. The whole cabinet stands 23.5 inches tall, within reach for a 3-year-old, and spans 40 by 12 inches against a wall. Engineered wood construction carries a total of 176 lbs. Assembled weight is 41 lbs, and the open layout leaves nothing hidden behind a door.
