This ladder shelf fixes to the wall rather than standing on the floor, so the 30 x 12 in shelves float clear of skirting boards and radiators. Four tiers sit 12.5 in apart on a 6.5-in wide metal frame, each rated to 44 lbs - enough for stacked books rather than only ornaments. The unit measures 30 x 12 x 64 in and weighs 25.5 lbs in MDF and metal. Brown boards against a black frame give the pipe-shelf industrial look. Check the wall type and fixings before mounting and loading.
