ABSTRACT:
A portable tree seat has a main bracket, a seat portion pivotally connected to the main bracket, and a support brace for supporting the seat portion in an unfolded operative configuration wherein it is in a generally horizontal attitude. The support brace includes a positive stop and a spring that cooperate to automatically locate the support brace in a position for engaging the main bracket when the tree seat is unfolded. The tree seat further includes a rod so located on the seat portion that a rope tied thereto is tightened to maximum tension on the vertical support when the seat portion is lowered from a raised position to the unfolded operative configuration.
