A family of seating with essential geometric lines. The circular seat and square back have the exact same area, and intersect to create an opposition of forms, where one geometric figure or the other becomes predominant depending on the vantage point. The circular frame in solid ash wood accommodates the legs, in the same material, and permits attachment of the curved wooden back. The seat is padded and covered. The Riquadra family includes a chair, a chair with armrests and a lounge chair.
