Abstract: A seat assembly. The seat assembly is adapted for use in entering confined spaces or otherwise entering spaces through confined entryways. The seat assembly includes a seat that is slidably disposed along a track. In one embodiment, the seat is rotatable. The seat assembly further includes a wire or tether that has multiple clamps positioned along its length. The assembly is utilized by placing the track such that it extends through a confined entryway and then securing the clamps about the perimeter edge of the opening such that the tether is held taut. The tension in the wire exerts a force that maintains the track, the seat, and a user or any equipment thereon in a horizontal position through the opening. Users can the utilize the slidable seat to enter and exit the confined opening with minimal difficulty.
