An assistive walking rear entry device including a main frame, elongated upright body weight support members connected to each side portion of the main frame and two elongated leg members connected to each body support member one extending forwardly, the other extending rearwardly, each leg member including a rollable member attached to a distal end portion thereof. An elongated seat is attached to and supported on a lower portion of a centerpost, the centerpost being supported on the main frame. Rearwardly opening lateral torso supports are attached to the upper portion of the centerpost and make supporting contact with the thoracic area and for propelling the device during a walking gait. The seat is positioned against the perennial region to support the pelvis and to help propel the device on a "hands free" basis. The body weight support members are preferably multi-function for body weight support during a walking gait and preferably are tied together by a cross member to insure identical side-to-side displacement.
