What is the best small treadmill for home use?

Best small treadmill for most homes: Echelon Stride. It folds flatter than most treadmills, is easier to store upright or under furniture, and still feels more like a real treadmill than many ultra-compact walking pads.

If you mainly want under-desk walking, choose UREVO 2-in-1 Under Desk Treadmill instead. If you want a compact but more serious running option, look at the Horizon T101—it is larger, but better suited to regular jogging.
