Transform classrooms into active learning environments with on-demand sit-stand desks. With the simple squeeze of a hand lever, kids can change from sitting to standing. This adjustment capability, along with the desk's ease of mobility, gives an educator unparalleled flexibility in arranging their classroom for the lesson. This LearnFit is optimized to provide sit-stand adjustment for students in grades 7 through adult when using standard classroom chairs for seating. For elementary-school students ages 6 and above, this LearnFit is an ideal adjustable standing desk (match it with a taller stool to enable occasional sitting for elementary students).
