Embodiments of a walker are shown, the walker including two patient-load bearing support tubes each having a padded underarm support for seating in the armpit of a patient, an adjustable-height load bearing tube and a rubber tip. Connected to each of the patient-load bearing tubes are two L-shaped legs with a wheel disposed at the end of the leg and a grip disposed on the leg for a patient to grip when the walker is in use. A main tube is connected between the two legs and defines the width of the walker. The height of the patient-load bearing tubes may be adjusted from an extended position in which the padded underarm support is seated in the armpit of the patient to a retracted position in which the padded underarm support does not interfere with the patient's use of the walker.
