A lightweight, versatile stool for sportsmen and other applications comprises a seat and folding front and rear leg components pivotally attached thereto. The rear leg component establishes a plurality of rearward points of ground contact, whereas the front leg establishes a single point of forward ground contact. A set of shoulder straps preferably attached to the rearward leg component allows a user to carry the stool on his/her back with the leg components folded toward one another The front leg component is length-adjustable, and a bar is provided for attaching a backpack or other accessories. The seat swivels and tilts relative to the front and rear leg components to accommodate differing terrains and to provide comfort. The forward leg component may be nested in the rearward leg component in substantially the same plane for a low carrying profile. The seat has a padded upper surface which rests against the back of a wearer to provide comfort while using the shoulder straps.
