Montreal-based designers St Ely have created a sofa made up of three interchangeable modules with sliced-off corners. St Ely is a collaboration between industrial designer Eugenie Manseau and architect Hubert Pelletier. The seating has been launched by Lerival, an American design house that connects furniture design with architecture.

“We think the back view is as important as the front or side view. By expressing the fold on the back side we created a formal detail that is coherent with the front view and that animates the back side,” Pelletier said.
