Abstract: A portable, folding, outdoorsman's seat designed to be hung from the trunk of a tree. The seat is adjustable for height, tilt, and girth of the tree, and comprises a sling-type seat suspended from an integral rope harness. The ropes attach to the seat through a pierced sleeve arrangement allowing for tilt adjustment, and to each other through metal plates such as tent-rope adjusters or the like. The seat may be carried in a jacket pocket and easily erected without assembly.
