Three tiers of open shelving divide into eight cubes so books, toys and decor can be sorted by size and kept easy to see. The 48 x 12.5 x 36.5 in frame is built from engineered wood MDF with thickened boards to support daily use. Each cube holds up to 44 lbs, while the top surface supports up to 132 lbs for stacked books or display pieces. Large 23 x 12 x 10.5 in cubes and smaller 15 x 12 x 10.5 in cubes fit both tall albums and compact bins. A raised edge along the top helps keep displayed items from sliding off, and anti-tipping kits and non-slip foot pads help stabilize the bookcase against a wall.
