Slim at 8 inches deep and 22 inches wide, this three-tier bookcase slots into the gap beside a desk or a bed without crowding the walkway. Each shelf spans 20.5 inches with 12.5 inches of headroom, enough for hardcovers standing upright. Round feet lift the base off the floor, screw hole covers hide the hardware, and an anti-tipping kit secures the frame to the wall.
