Abstract
A tree climbing apparatus consisting of two movable platforms, each of which is secured to the tree trunk by a flexible strap that has a non-scratching cover that will not harm the bark of the tree. Each of the flexible straps has a construction that includes an elastic stiffener that causes the flexible strap to be self-straightening when one end of the flexible strap is removed from the platform.
