Key is a glass-topped low table made from four interlocking frames, secured by eight bolts. The frames tesselate to form the outline of a truncated square pyramid or a type of geometric prism, with the angle of each bend and the relationship between the base and tabletop being dictated by the hexagonal form of the steel bar.

Both Hex and Key utilise the inherent precision of hexagonal geometry. The hexagon, with its six equal sides and angles, is a naturally occurring shape found in everything from honeycombs to crystal structures. Known for its efficiency, the hexagon tessellates perfectly, minimising wasted space and creating strong, compact structures.

In the case of hexagonal bar, its six flat surfaces provide multiple points of contact, making it difficult to rotate freely, unlike a circular or round bar, which has no fixed flat surfaces to resist such movement. Its non-rotational form simplifies the bending process, with six pre defined bending axis allowing for the creation of precise components and seamless, stable assemblies.
