8. The seat cushion of claim 1 , wherein the one or more fasteners is a slideable fastener.
9. A method for carrying a pressure-distributing medium in a personal mobility vehicle cushion, the method comprising the steps of:
a) providing a cushion cover having a pocket with a first portion of a hook-and-loop type fastener in the pocket;
b) providing a pressure-distributing medium with a second portion of a hook-and-loop type fastener;
c) inserting a pressure-distributing medium in the pocket;
c) securing the pressure-distributing medium to the inside of the pocket by mating the first and second portions; and
d) inserting a base in the cover so that the pressure-distributing medium is positioned above the base.
10. The A seat cushion for a personal mobility vehicle, the seat cushion comprising:
a base; a pressure distributing medium with a first fastening element supported by the base, the pressure-distributing medium having a first fastening element; and
a cover covering the base and the pressure-distributing medium, wherein the cover comprises:
a pocket for receiving the pressure-distributing medium having a second fastening element within the pocket; securing the pressure-distributing medium to the inside of the pocket by mating the first and second fastening elements; and
top and bottom fabric panels joined together with an opening provided therebetween that is selectively opened and closed via one or more fasteners, wherein the pocket is formed from a piece of fabric secured adjacent an underside of the top fabric panel so that an opening is presented along one side of the pocket, and wherein the pocket opening is at a front end thereof.
11. A seat cushion for a personal mobility vehicle, the seat cushion comprising:
a base; a pressure distributing medium with a first fastening element supported by the base, the pressure-distributing medium having a first fastening element; and
a cover covering the base and the pressure-distributing medium, wherein the cover comprises:
