In Incas only the two sloping planes have to withstand stress and strain due to the weight of the top, while the vertical planes do not in any way support the structural system. Today Incas is available in other stone materials and with suitable finishes, now for the first time it is being produced in a new and sophisticated solid wood version, proving that every great idea can be further developed without losing any of its force orpoignancy. Tables made from Extraforte stone are also suitable for outdoor use.
