An apparatus that combines the functionality of a walker with that of a single crutch is herein disclosed. The apparatus provides for one crutch that comes up from the side support of the walker and thus the side of the user's body and is adjustable in height, as is the walker support handles, such that the invention can be customized for any sized user. The adjustment is facilitated by use of spring pin slip fittings, and thus can be adjusted in a matter of minutes without tools. The crutch support can be easily moved from the right to left hand side of the walker by use of a removable clamp system. It is also envisioned that certain models of the invention can provide crutches on both the right and left hand side of the walker simultaneously, based upon the needs of the patient. When not in use or not needed, the invention folds up in a manner similar to a conventional walker thus providing a low profile for ease of storage.
