Designed in 1994 by Ron Arad, The work of Israeli-born London-based designer has played a significant role in the way our contemporary furniture looks. A careful analysis of extrusion technology has allowed the creation of a curvy bookcase which assumes any desired shape, without compromising toughness and functionality.

The basic idea was to bring innovation into the world of bookcases, creating non-orthogonal shapes and using different materials. The bookcase was originally designed as a thin blade of steel, but after the meeting with Kartell , a historic Italian design company specialized in the field of plastics, it is now commercially manufactured in PVC, which gives it both strength and bendability.

A key aspect of the design is that it is attached to the wall according to the wishes of the installer which means that it can be fixed in a spiral, a gentle curve and every shape in between. This is a significant point, as few designers actively promote the end user having the final say on the aesthetics of their product. As a shelf, its thinness and flexibility give it a precarious appearance but upright dividers at various intervals mean that books can be safely displayed even at crazy angles; the topsy-turvy look is rather unnerving at first sight.

The name of the project was designed by the same Ron Arad , as the shape of the object resembles a worm has been given the name of Bookworm, which is the union of the words book and worm.

After the meeting with Kartell, Bookworm was produced in technopolymer , a plastic material of which the company is a leader. To create the technopolymer library in series , the company has created a research team to find the best extrusion technology, remaining faithful to the original product.
