ABSTRACT:
A portable tree seat and platform for standing is provided which is completely stable and avoids the drawbacks of the prior art tree seats which have a tendency to pivot or rock. The portable tree seat includes a substantially flat seat member, a screw threaded fastening member for threaded penetration of a post or tree, a V-shaped stabilizing member attached at its wide end to the seat member, and having a peg member connected to the lower end of the V-shaped member and having a penetrating point thereon for penetrating a post or tree to which the portable seat is adapted to be attached to. Thus, the seat member is totally adjustable in any direction to insure that the seat is always maintained in a horizontal plane relative to the ground and relative to its longitudinal and transverse axes, regardless of the tree angle or configuration.
