A length adjustable cane for assisting a user with mobility on surfaces having different heights includes a cylindrical outer tube and a cylindrical core member configured to be received in the outer tube and telescopically movable between retracted and extended configurations relative thereto. A handle is connected to an upper end of the core member. An actuator lever is coupled to the handle and accessible to a hand of the user, the actuator lever being movable between actuated and released configurations. A latching mechanism is situated in the outer tube proximate the open end thereof. A drawbar having an elongate configuration is positioned in an interior of the core member. The drawbar includes a first end coupled to the actuator lever and a second end operatively coupled to the latching mechanism. Operation of the actuator lever operates the latching mechanism to selectively allow length adjustment of the cane.
