The bookcase comprises just a few ingeniously interconnected elements, which show Gianfranco Frattini's attention to the laws of statics and dynamics. It has four vertical struts and two rack and pinion poles at the two ends, all crafted from solid olive wood. The shelves, produced in MDF with olive essence veneer, can be positioned in the holes along the struts as desired with a minimum of eight and a maximum of 12 shelves. A special metal cylinder is attached to the ceiling to hold the bookcase in place. The Albero's frame is attached to this and the floor thanks to two adjustable metal ferrules that ensure its stability. The height of the bookcase can vary between 2.66 m to 3.26 m.
