Books at the top, bulk below: the tiered upper racks hold magazines, stationery and picture books with covers turned outward, while the 2 wide shelves underneath take building blocks and bigger toys that would swamp a narrow rack. Loading follows the same logic as the ratings, 11 lbs on each upper rack and 33 lbs on the lower shelves, so the weight sits near the floor. Engineered wood panels are thickened at the base for stability and finished without odor, and an anti-tipping kit anchors the unit to the wall. Height stops at 32 inches, low enough for a child to reach the top row unaided, with a 29 by 12 inch footprint against the wall. The assembled cabinet weighs 36 lbs.
