Someone had to tell me about these nifty swing-out seat retainers, and that was after I'd spent an afternoon designing my own solution. Oh well ... better to learn late than not at all, I suppose. I checked my owner's manual and didn't find a thing on these gizmos. You can easily adapt them to an Aero. The Aero seats will stand up to being forced to lay flat for reasonable periods of time, although extended periods would probably deform them pretty badly.
