The seat comprises a front end and a back end interconnected by foldable sides and a top which can be swung into a vertical position and inserted into the back and when the seat is collapsed. The ends are shallow, rectangular boxes with their smaller surfaces oriented top and bottom when the seat is erected. It further comprises two handles detachably attached to the back end and stored inside the front end when the seat is collapsed. The sides are hinged such that their centers fold inward when the seat is collapsed, allowing the ends of the seat to move together and be latched together. There are four caster, one at each corner of the bottom of the erected seat and a foot rest which swings out of the front of the seat. The casters are lockable to prevent the seat from rolling when desired. A carrying handle is attached to the front end of the top of the seat and is accessible for carrying the seat when the seat is collapsed with the top inserted and locked into the back end. Erected, the seat is sized to fit in the aisles of commercial aircraft. Collapsed, its size and shape conform to airline regulations for carry-on luggage.
