L45 by Guglielmo Poletti for Desalto | A set of tables with an ingenious constructional geometry creating an effect of seemingly precarious balance

Desalto presents L45, a series of tables by the designer Guglielmo Poletti ranging from coffee tables to medium and large dining tables with rectangular or square tops. L45’s innovative concept is expressed in the project’s structural requirements, which revolve around a detail: the joint between the leg and top is limited to the meeting of their respective vertices.

The design involved careful study of constructional geometries to create the impression that the ends of the table top rest precariously on four single points of the supporting structure. The top, consisting of a simple parallelepiped, houses the complex mechanism anchoring it to the structure, making it both structural and load-bearing.

The range is available in hand-made textured finishes, in different types of wood or Fenix ​​laminate. The process of industrial production includes a substantial component of manual skills, without which it would be impossible to attain such outstanding detailing. A considerable degree of accuracy is required in welding the joint between leg and crosspiece, and it is essential for the edges to match perfectly.

To create the detail of the convergence between the legs and the table top, a mechanism of assembly was specially designed to ensure absolute precision. In the case of some finishes, the texturing process is also done wholly by hand, like the galvanic Peltrum finish.

At a glance


What is it and who is it aimed at?
It is a new series of tables available in many variants – from coffee tables to small tables as well as medium and large dining versions.
What is the design concept?
The seminal aspects of the project are embodied in a detail: the minimal point of contact between leg and table top in the joint where their vertices meet.
How is it made structurally and with what materials?
The structural steel frame consists of four legs jointed with their respective crosspieces, in turn coupled to the load-bearing lattice to which the top is fixed. The top houses within its thickness the mechanism anchoring it to the structure.
How is it produced and where?
The tables are produced in-house with the exception of the tops, which are finished externally. The industrial process is accompanied by a notable manual component.
How is it manufactured?
Each piece consists of a steel frame machined by numerical control (CNC) systems. The subsequent welding and finishing process, done in-house, is completely manual.
What makes it special?
The rigorous geometry of the corner contains a technical complexity very skillfully concealed, a feature embodying the company’s distinctive character: its extraordinary productional know-how.
What is it like?
Rigor, purity, lightness.
In the designer’s own words
“The company is the ideal interlocutor to express my design vocabulary on an industrial scale, thanks to our shared interest in the investigation of form, never as an end in itself but directed towards the search for the structural limit.”
