Four storage levels combine a 2-tier shelf and four open cubes so books, decor and storage bins share one 36 x 13.5 x 47 in bookcase. The top shelf measures 36 x 7 x 2 in to keep smaller items visible, while the second shelf at 36 x 13 x 13 in holds larger objects. Two middle cubes at 17 x 13 x 12.5 in and two differently sized bottom cubes help separate items by size. Engineered wood shelves and metal legs support up to 320 lbs in total, and a 4.5-in raised base, adjustable feet and two anti-tipping devices work together to improve stability and make floor cleaning easier.
