A walker for assistant people ambulating, particularly on stairs climbing, is a free standing frame comprising a pair of reverse U-shaped frame members that are interconnected by braces at its sides and front, having the walker open on its rear side to allow access by the user. The horizontal parts of the U-shaped members provide handles for gripping the walker. A pair of adjustable front legs are telescopically inserted in the frame and are held in fixed position relative to the frame by a spring lorded pin mounted on the frame passes through the hole on the frame and the front leg. In one embodiment, hand actuated controls mounted on the handles allow the user to pull the pin out of the holes whereby the front legs extend by falling under the force of gravity to the desired length where the pin re-locking the front legs. Alternatively, the front leg are shortened by unlocking the front legs, pressing the front legs against a fixed surface until the legs are at the desired length where the pins are re-locked. In another embodiment, a reversible electro-Magnet force driving the bolts in and out the holes to locking or unlocking the front legs.
