The table legs are expelled outwards remaining constrained and fixed by the central ring when screwing together two equal truncated cones. This creates a central knot that reveals the mechanism and creates a strong visual impact. This intelligent solution lets us mount and dismount the table with a single gesture and a single screw. At the same time the rounded legs allow the mechanization of a round groove where a standard rubber ring naturally fits, softening the transition between iron and glass. This provides an ideal support and avoids the use of a drop of silicone.
