Four ledges rather than a single shelf let books face outward at a child's eye level, which is how a nursery bookshelf actually gets used - covers visible, spines ignored. Each is 24 x 5 x 2 in in solid fir wood with a 16.5-in recommended hole spacing to hit wall studs, and each holds up to 16.5 lbs. The set weighs 4.5 lbs in total. Mounted at different heights they turn a blank wall into a display for picture books, framed photos or small toys. A user guide is included with fixing guidance.
