ABSTRACT:
A tree-climbing hunter's support apparatus includes a tree-gripping frame section and a collapsible frame section that extends from the tree-gripping section to unfold and support a flexible lounge seat. The positioning of the seat for supporting a hunter provides for a strong and safe tree-gripping lever action to prevent the apparatus from slipping down the tree. The flexible lounge seat permits the hunter to remain safe, comfortable and motionless for long periods. The hunter can climb and descend the tree with the assistance of the apparatus, and can conveniently transport the apparatus on his back.
