An integral stair climber, lifter, bracer and walker includes a frame which has a pair of spaced apart upright struts or members. A cross piece extends between the upright members two-thirds of the distance up the upright members. A handle portion is attached to the upright members at the upper end thereof. The handle portion includes a pair of opposed, vertically disposed segments which are receivable on the upright members. A grip pair is located on top of each vertically disposed segment and includes two grips, one located posteriorly to a vertically disposed segment and another extending anteriorly to the vertically disposed segment. A transverse element extends between the two vertically disposed segments or struts. Each anteriorly located grip is connected between the transverse clement and the vertically disposed segment. A four-footed base is located on the lower end of each upright member and is orthogonal thereto. Each base includes a plate to which four feet are attached and which is fixed to the upright member. Each anteriorly located grip is tilted upwards at approximately a 45 degree angle and slightly inwards towards the transverse element at approximately a 25 degree angle.
