A walker for assisting persons with varying degrees of physical ability is provided with an adjustable strap. A user opens a portion of the walker and enters the walker, and then the user closes the portion of the walker to enclose himself or herself in the walker. The user is positioned over an adjustable strap, and the adjustable strap is in an extended position. The adjustable strap may then be retracted such that a seat disposed on the adjustable strap rises and contacts the user to bear at least a portion of the user's weight.
