Eighteen shelves in this tall bookshelf adjust across three height options so you can size the 24 open cubes for paperbacks, binders or display pieces while keeping contents visible. The 6.5-in depth lets you line up storage against a wall to save floor space in narrow rooms or home offices. Each cube supports up to 11 lbs and the top shelf holds 44 lbs to handle book collections. Engineered wood construction, matching fastener hole covers and an anti-toppling device contribute to a stable, finished storage unit.
