Adjustable upper straps extend from the four corners of a collapsible seat assembly and terminate at a central O-ring. A groin strap extends from the central ring to a portion of the seat assembly. A tree ascender strap is also connected to the central ring, and has a latchable hook which can be used to encircle the trunk of a tree and secure the climber as he climbs. A back strap and shoulder strap extend from the central ring and help to restrain a hunter within the assembly both while climbing and while in an elevated position in the tree. A main lead securing strap extends from an extension strap connected to the central ring and has a buckle which allows it to be secured around a tree above the head of the hunter. The main lead securing strap is looped through itself in such a way that the strap chokes the tree trunk within itself to prevent slipping on trees with smooth bark. In a preferred embodiment the seat assembly has two identical seat segments which are hinged to a rigid downwardly extending spar, with a plurality of straps in tension serving to keep the seat assembly in its erected condition when in use. Alternatively, collapsible seat assemblies employing flexible strap webs may be used.
