The assembly includes a frame base and forward and rearward frame portions each attached to the frame base by a ratchet arrangement. A pair of leg members extend downwardly from the frame base. The forwardmost leg member is pivotally attached to the frame base so as to be swingable away from the lower back of the carrier of the convertible backpack assembly. Webbing material is be disposed over the frame portions and across the frame base, to define the front and back of the backpack as well as the back, seat and leg support portions of the chair. The seat portion may have its tension adjusted under the frame base, to allow greatest sitter comfort. A pair of side panels of webbing material are removably disposed between the front and rear frame portions to define the sides of the backpack assembly. The side panels may either attach to the sides of webbing material over the front and back frame portions or form part of a separate liner that functions as the container for the backpack between the front and back frame portions.
