Two open cubes on this floor standing bookcase keep books, photos, and storage boxes easy to see and reach while making use of compact floor space. The 5-position adjustable shelf lets you change the height between the upper and lower compartments to fit different item sizes within the 15.5 x 11 in inner shelf area. Measuring 16.5 x 11.5 x 21 in overall and made from engineered wood MDF, it supports up to 66 lbs on the top and 44 lbs on the shelf. Edge-sealing and anti-slip foot pads help protect floors and keep the unit steady.
