An adjustable walker includes a tubular frame construction having front and lateral telescoping tubes defining a walker space for a user. The lateral tubes have handgrips suitable for being grasped by a user. The front telescoping tubes are adjustable in length to adjust the width of the walker space for the user and the lateral telescoping tubes are adjustable in length to adjust the height of the handgrips. Locking mechanisms are provided for locking the front telescoping tubes and the lateral telescoping tubes. Actuators on the handgrips selectively unlock the locking mechanisms to allow a user to adjust the width of the walker space and for selectively unlocking the second locking to allow a user to adjust the height of said handgrips to adjust the height and/or width of the walker by use of said actuators on said handgrips without bending or letting go of the walker.
