What shape is the sea? It can be seen in rocks shaped by water, in the small waves that extend endlessly on the shore when the waves retreat.
Following this suggestion, Roberto Semprini has designed Onda for Lab23, a bench in Hypergranite, the fiber-reinforced composite material made of a polyester resin and marble dust, resistant to wear and weathering.
Hypergranite comes in a range of colors. The internal structure is composed of a galvanized steel frame and two stainless steel plates for ground attachment.
