Standing desks are sweeping the nation—from homes, to offices, and recently even to schools. As all things old are new again, standing desks have been popular in schools before—but not in quite a while. During the 19th century, it was common to see standing desks, and even some of the first adjustable height desks in schools. They were implemented more commonly in universities and for older students, as back then young students were required to stand each time they answered a question anyway.
