Abstract: A combination backpack and seat device is constructed of first and second U-shaped frame members, each having a transverse portion intended to be horizontally disposed during use and parallel side portions intended to be vertically disposed during use. The frame members are pivotably interconnected at a site within their side portions. A fabric panel extends between the transverse portions of the frame members and serves as a seat when the frame members are pivoted to maximum separation, representing the seat mode of use of the device. In the seat mode of use, the lower extremities of the side portions of the second frame member contact the ground, and a strap of adjustable length secured to the side portions of the second frame member is caused to tautly embrace a tree adjacent the ground.
