Abstract
Abstract A combination backpack and stool is provided with a frame having a seat-defining member upon which a user may sit, a ground-engageable member for supporting the frame upon a surface, and an upright pedestal member rigidly coupled to and between the seat-defining member and the ground-engageable member so as to establish a space therebetween. A flexible material encloses the defined space to provide a storage compartment for articles. A pair of shoulder straps are attached to the frame and thus allow a user to carry the frame in the form of a backpack. When periodically resting, however, the frame may be set upon the ground so that the user can sit and rest upon the seat-defining member.
