Seven cubbies in two sizes - 13 x 9 in and 9 x 9 in - sort books from stationery without everything sharing one long shelf, and three of those shelves move through five positions within 1.2 in. Total capacity across the unit is 210 lbs, with 55 lbs on the top and 22 lbs per cube. The bottom bay measures 26.5 x 17.5 in for a monitor. The hutch stands 37 x 10 x 31 in and weighs 31 lbs in white engineered wood and MDF. Cube height is 12.5 in, tall enough for most hardbacks standing upright.
