Our patented U-shaped base is ultra-stable and surrounds you to prevent you from falling! Unlike other walkers, the U-Step as a solid welded base, that does not wiggle, so you will feel very secure when walking. The majority of the weight of the U-Step is in the base, which provides you with a low center of gravity for greater stability. In addition, the “U” shaped base surrounding you and braces you in every direction from falling. You feel as stable as you would feel holding onto another person’s arm. Other walkers only partially brace you from falling.
