This is the desk that spans any treadmill to provide a generous, easy-to-use work surface for completing office tasks while you walk. Walking a mere 1 to 2 mph while working on a computer or making phone calls can reduce stress, improve circulation, and burn twice as many calories as a sedentary position--without inducing heavy breathing or sweating. The 72" x 34" desktop accommodates a computer, telephone, and paper work, it adjusts from 46 1/2" to 56 1/2" high, and its u-shaped design keeps items within reach, providing the same comforts as a traditional desk. It has a four-level file tray, a manuscript stand that holds reading material upright, two cup holders, and beveled desktop edges to ensure arm comfort while typing. The substantial powder-coated steel frame and steel reinforced polycarbonate desktop withstand years of use. Folds to 1/2 its operational size for storage. Assembles in 45 minutes. Treadmill not included. 72" W x 34" D x 46 1/2" to 56 1/2" H. (83 lbs.)
