The Array seating collection—whose name comes from the concept of a matrix, or ordered pattern, found in the languages of computer science—uses geometry to create a visual effect that varies depending on the viewer’s perspective. Designed by Zaha Hadid for Poltrona Frau Contract, the auditorium or theater seat folds diagonally upward when not in use to form a triangle with the back and base.
