Garden and Outdoor Furniture Design Whale Tail Sitting Bench by Enrique Mínguez Ros This piece of urban furniture is a versatile element for both indoors and outdoors. The shape of the seat and its support makes the bench resemble the tail of a whale without compromising its ergonomics and stability. A thin layer of fibreglass covers its inner core of wood or concrete enriched with recycled plastic. It can be placed alone or in small groups.
