One of the six shelves adjusts through three positions in 1.3-in steps, so a row of tall art books or a stack of box files can be accommodated without rebuilding the unit. The bottom bay runs 36 x 18 in, wide enough for a monitor and a keyboard tray beneath. Load ratings are graded by level: 66 lbs on the top tier, 55 lbs at the bottom and 22 lbs on the adjustable shelf. The hutch measures 37 x 9.5 x 33.5 in and weighs 24 lbs in engineered wood and MDF. The natural finish shows a light wood grain.
