Ergotron's LearnFit desks transform static classrooms into active learning environments. Utilizing the desk's Constant Force technology, students can change their own desktop height on demand, so a comfortable position can be achieved whether sitting or standing or using different types of technology such as tablets or netbooks. The casters enable easy movement for reconfiguring classroom layout and student collaboration. Desks can be rolled together for small group breakouts and quickly returned to the full classroom configuration when done. Standing more throughout the day increases blood circulation, burns more calories and helps maintain muscle tone and insulin effectiveness. The LearnFit desk retails for $500.
