The Sun Station is a lightweight submersible support system able to accomodate any number of accessories. This is done via a universal adaptor at it's top. It's just over 8 lbs empty, and uses water as natural ballast in it's base. It's lowest level is 2.5 feet, and can raise to 4 feet (to break the surface of the water). It comes out of the box with the base, riser, universal adaptor, and reversible top plate (stool on one side, drink indents on the other).
