Abstract
A seat cushion for an aircraft seat includes a plurality of rear edge securing straps attached to the lower surface of the seat cushion. The rear edge securing straps each have a free end that includes a pull-the-dot fastener that engages a corresponding pull-the-dot fastener at the rear edge of the seat pan. The length of the rear edge securing straps is selected so that when the seat cushion is installed, the rear edge securing straps are pulled substantially flat so that the seat cushion is firmly held in place. The seat cushion is easily removable because the pull-the-dot fasteners are at the ends of the rear edge securing straps rather than affixed directly to the bottom of the seat cushion. Therefore, when the front edge of the seat cushion is released, the seat cushion can be lifted up enough to allow the cushion to be released without pulling at the bottom of the seat cushion.
