Volant Sofa is designed by Patricia Urquiola, and the Volant range includes the sofa, armchair, chair, and a stool, if you want the whole collection. The structure is basic and self-sufficient. The frame of the base appears orthogonal but in actual fact is a trapezium for adapting to the line of the back and seat. This leads to a shape dichotomy between regularity and irregularity, also in the perception of the seat elements which, despite the fact they seem flat, have curved sections to provide extreme comfort.
