A three-part storage unit that treats large toys and small ones as separate problems. At the bottom sits a rolling toy box measuring 22-in by 14-in by 12-in and rated to hold 22 lb, deep enough for ride-on toys, bulky building sets or a run of hardback books that would never fit a shallow bin. It sits on lockable wheels, so it rolls out to wherever a child is playing and locks in place once it gets there, then rolls back under the frame when the floor needs clearing. Above it, three removable plastic bins at 11.5-in by 7.5-in by 5-in and rated for 6.5 lb each take the small pieces that get lost in a big box: figures, cars, craft supplies. Each bin lifts right out for sorting and rinses clean, which matters for the bins that end up holding sticky things. A top display shelf finishes the unit at 30-in tall on a compact 25-in by 15-in footprint, and the whole layout is set at a scientific height so a child places and retrieves items independently rather than waiting for help. The frame is sturdy wood with a strong load-bearing capacity, built from MDF with PP bins and iron tube supports, and the whole assembly weighs only 21.5 lb in total. Materials are non-toxic and tasteless, chosen for long-term use in a room where a child spends real time. All corners are rounded so nothing catches a child's clothes or skin. It works in classrooms, a kids playroom, daycare, school and homes, and assembly and cleaning are both quick.
