Tronco appears to be a very basic chair, its seat formed from planks of wood joined together and mounted on round dowels. It is unlike any of Mattiazzi’s previous designs that have displayed a sculptural softness achieved by mechanically removing material. Instead, Tronco’s character is formed from solid strips of wood in what appears a very elementary construction, yet its simplicity is the result of iterative experimentation and high regard for material honesty. Tronco has surprisingly natural comfort and works well in multiples, not just alone. Its form is modest enough so that it takes on the appearance of "texture" when shown in numbers. Tronco, in effect, creates a terrain of its own in any architecture.
