Abstract: A walker is disclosed that may be adjusted in width during use for allowing the user to pass safely through narrow doorways or passageways. Walkers of the present invention have crossbars at a front thereof constructed of telescoping tubing and locking/unlocking mechanisms. During use, the telescoping tubes may be unlocked so that a smaller tube may be moved into a larger tube, reducing a width of the walker. In other embodiments, a lead screw assembly may be rotated in order to reduce width of the walker. In yet other embodiments the walker may be automatically increased or decreased in width responsive to the tubes being unlocked.
