Ten cubes stack 71 in up a footprint only 20 in wide, so a paperback collection climbs the wall instead of spreading across the room. Most openings are 9-in squares at 7.5 in of height, sized for spines and small frames, while a wider 18.5-in by 9-in by 11.5-in middle compartment takes binders or a stack of magazines. The base drawer hides chargers and stationery behind a cut-out handle, and a stopper prevents it from pulling free of the runners. A guard rail edges the shelves, and the frame is rated to 205 lbs.
