Six open tiers create vertical storage for books, photos, storage boxes and ornaments while keeping everything visible and easy to reach. The 23.5 x 9.5 x 70 in MDF engineered wood frame fits against a wall to save floor space, and each 22.5 x 8.5 x 11 in compartment helps you sort items by size or use. Thickened boards with edge sealing support up to 200 lbs in total. Two anti-toppling devices secure the bookcase to the wall and protective foot pads help enhance stability and protect floors.
