Clean-up becomes something a child can finish alone when the bins are on wheels: two drawers glide out of the base, take 33 pounds each and hold a 13 by 10 by 6 inch load of blocks or figures, then roll back with a nudge. Above sits a three-tier bookshelf, 11 pounds per tier, for picture books and small decorations. The natural engineered wood carries a wave-shaped trim across the top and rounded corners at every edge, and the surface wipes down after craft afternoons. Two anti-toppling devices anchor the 32.5 by 12 by 30 inch frame to the wall. Net weight is 30 pounds, so it stays put in a nursery or playroom once loaded.
