Abstract: A submersible, foldable seat for use in a hot tub. The seat is folded down to be used as a seat and folded up to provide an increased unobstructed area for use of the hot tub for other activities such as exercise. The foldable seat uses pivoting attachment members which allow flush connection to the curved hot tub wall. Frame members of the seat use connectors with transverse apertures to rotatably receive tubular portions of the seat frame to allow folding of the seat.
