Wheeled walker with an integrated safety system includes a frame, wheels on the frame to enable the frame to be manually moved along a surface, and a belt/tether apparatus including a belt adapted to be attached to a person using the walker and at least one tether connected at a first end region to the frame and at a second end region to the belt. The tether may include an elastic portion that provides a proportional tension as distance beyond a slack distance of the elastic portion increases. This limits separation of the walker from the person attached to the belt.
