Abstract: An adjustable tree seat for hunters includes a base member adapted to be secured to a tree or the like by a pair of elongated flexible straps having separable fastener means on their opposed ends. An open and tubular support member is retained on the base and a seat post projects out of the top of the support member and telescopes within the support member. Holes at spaced intervals on the seat post may be aligned with a hole in the base and a pin passed through the aligned holes to secure the seat post at a controlled elevation relative to the base. A bicycle-type seat is supported on the free end of the seat post and a foot platform is pivotably attached to the bottom end of the base by flexible straps which allow the platform to extend normally to the tubular member or to be aligned parallel to the tubular member for transportation and storage.
