Oak-toned boards with gray accents give this three-tier unit a warmer finish than the plain white version of the same frame. The 15-in gap between shelves is the widest in this range, cut for lever-arch files, tall hardbacks and stacked storage boxes. Shelves measure 23 x 10.5 in and hold 66 lbs each. Boards are 0.6 in thick engineered wood, giving 24 lbs of weight across a 23.5 x 11.5 x 39.5 in frame. An anti-tipping kit ships with it, and assembly is required from the enclosed instructions.
