The arch over the top shelf is the point of this bookcase - a curved metal profile that turns a plain four-tier rack into a piece with a silhouette, suited to a hallway or an alcove where it will be seen from across a room. Four wide shelves each hold 33 lbs on a frame measuring 37.5 x 13.5 x 61.5 in. Rustic brown boards sit in black metal, and the whole unit weighs 29 lbs - light enough for one person to position before anchoring. One bookshelf and an instruction sheet ship per carton.
