Dividers split each of the four shelves into sections, so books stay upright without bookends and the 29-in width does not become one long row of leaning spines. Chipboard shelves on a metal frame carry 220 lbs in total across a 29 x 12 x 61 in unit weighing 44 lbs - among the heavier four-tier frames here, which shows in how little it flexes when loaded. The open construction lets it stand against a wall or divide a space. Rustic brown boards give it a warm industrial finish.
