A 2-in back panel behind every shelf keeps books and frames from being pushed off the rear of an otherwise open unit, which matters when a 61-in bookcase stands away from a wall. Five shelves at 22 x 11 in sit 11.5 in apart and hold 33 lbs each. The frame is engineered wood with metal, measuring 24 x 12 x 61 in at 26.5 lbs - light for its height, so anchor it once loaded. The wood-grain finish over a dark frame gives it an industrial look for a study or a living room alcove.
