Forest is a desk partition that enables students to focus on their studies with positive feelings. Through observation research in a classroom of an elementary school, some students had difficulty concentrating on their assignments and isolated themselves from others to focus. The playfully shaped desk partitions in Forest let students build up their semi-closed space that helps them concentrate, through a creative process. It gives them autonomy to decide how high and how dense the Forest would be. Also, its playfulness encourages others to join the building, solving the problem of isolation.
