Folded to 6.5 in thick, this navy treadmill stores flat under a bed and rolls out on its transport wheels when needed. Raise the risers and the 4.75 HP motor drives the 49-in by 20-in belt from 0.6 to 10.5 mph; leave them down and it walks along at 0.6 to 3 mph beneath a standing desk. Five belt layers cushion each footfall. The LED touch screen adjusts speed and volume and displays pulse, calories, distance and time, while a color light strip shifts with pace. Open footprint is 58-in W by 31-in D by 47-in H. Built from steel, ABS, PVC and MDF, it weighs 106 lbs and carries users up to 265 lbs. The remote control starts and stops it from desk height.
