Thirteen inches between shelves and 6.5 in from the lowest shelf to the floor makes this 63-in unit usable for tall books at every level rather than only the top bay. Five open shelves carry 220 lbs between them across a 26 x 13.5 in footprint. Well-processed thickened board sits in a metal frame for a total weight of 35 lbs. The open construction on all four sides means it can stand as a room divider as well as against a wall. Rustic brown boards against black metal give an industrial finish.
