ABSTRACT:
The invention relates to an apparatus for climbing an upright columnar member such as a tree, pole, or the like, using two climbing members. The first climbing member has a first upright member gripping structure and an adjustable platform spaced from the upright member to accommodate the body of the user in a sitting position. The adjustable platform is preferably a seat which is adjustable to permit the occupant to recline from an upright sitting position. The second climbing member has a second upright member to accommodate the feet of the user. One or both of the climbing members have a retraction device and locking mechanism for adjustably maintaining the climbing members in substantially horizontal position relative to the ground as the climber ascends or descends the tree.
