This chapter focuses on three language classrooms in a French secondary school to analyze how flexible seating gives the students’ body a much-needed freedom (to move in the classroom and to find coziness) in the long day that they spend at school sitting still on hard uncomfortable chairs. Our data consist in video-taped lessons using flexible seating and oral interviews with teachers and learners. Our analysis is based on classroom observations and analysis of content of the interviews to address how flexible seating redefines the place of the body in the language classroom. We will also discuss the benefits that teachers have noticed on learners as well as the feelings of the students regarding this specific pedagogy.
