A series of rectilinear components come together to create anything from an unusual-looking desk to a cozy corner sofa or a combination of the two. The Work Sofa by Dutch design studio Prooff gives office workers the freedom to change their furniture around to suit their task, whether they’re making a private phone call or collaborating on a project with co-workers.

The different configurations offer varying levels of formality, too, eliminating the need for rigidly defined spaces within a workplace so that any room can go from a brainstorming lounge to a more professional setting just by moving the various parts around.

The designers analyzed how people use furniture at work, doing some “intensive research into the activity of sitting and the nature of maximizing social activity.”

This led to the creation of five components that fit together like puzzle pieces. The way the pieces come together is ultimately up to the user, with virtually endless possibilities.
