A 2-cube bookcase built low and shallow, standing 21 in tall on a 16.5-in by 11.5-in footprint so it slides under a window sill or beside a sofa without blocking the view. The middle shelf steps through five positions across a 2.5-in range, so one cube can hold upright binders while the other takes paperbacks, photo boxes, or a fabric bin. The capped top carries up to 66 lbs for a lamp or a turntable, and the inner shelf takes 44 lbs. Sealed panel edges resist chipping where hands reach in, screw hole stickers hide the hardware, and anti-slip pads keep the 14-lb frame from scuffing hardwood.
