The bottom shelf starts 12 in above the floor, which keeps a vacuum, a radiator or a skirting board clear underneath and is only possible because the frame mounts to the wall. Six shelves sit 9 in apart across a 23.5-in width, sized for paperbacks, CDs and small decorative pieces, with 265 lbs of capacity in total. The unit is 8 in deep and weighs 22.5 lbs in engineered wood and metal. Wall fixings anchor it at two points for stability; a user manual is included with the ladder shelf.
