Sorry for double post...
Beech Bonanza Seat
Airline Seat Couch
Airbus Dual Seats
Airliner Seat Recliners
Airplane Tail (Make a table out of it or something)
If you want more your best bet would be just to buy an un-modified aircraft seat (like the first one I posted), and make some brackets or something to turn it into a normal chair. It's cheaper that way, and then you can brag to your friends that you have a REAL aircraft chair, and you made yourself.
