Corner Bookshelves, 72", 6 tiers, White

You get six tiers in the same footprint that a shorter corner unit would waste, and the 72 inches lets you run storage up to the picture rail where others stop at shoulder height. The white finish keeps the mass readable against pale walls, and the twelve inches between shelves fits standard hardbacks upright. You hold the tape at the junction of two walls and read the diagonal the unit will occupy.

You level the unit on the floor, anchor it to the wall before you load anything, then fill the tiers. The laminated engineered boards come numbered on our sheets, and the carton holds the fittings for the wall bracket. That is the order: floor first, wall second, then books.
