ABSTRACT:
A tree stand has a platform,a seat collapsible between a position overlying the platform and a position upstanding from the platform, and a climbing band for encircling the tree. The platform, seat and band engage the tree at three discrete points to afford stability. A safety rope is secured to the seat and has a Chinese knot for tightening the rope about the tree. A climbing aid is provided and includes a generally rectangular frame with one end frame member slidable toward and away from the opposite end frame member to adjustably lock in a selected position dependent upon the girth of the tree.
