Six open shelves on this 70-in tall bookcase create vertical storage for books, framed photos, decor and storage boxes while keeping everything visible and easy to reach. Each of the 6 tiers uses a thickened MDF engineered wood board with edge sealing for reliable daily use and a total weight capacity of 200 lbs. The 23.5 x 9.5 x 70 in overall size and 22.5 x 8.5 x 11 in inner compartment size help organize books and organizers. Two anti-toppling devices anchor the unit to the wall, and protective foot pads help keep floors free from scratches.
