15-420Ever been on a long air flight and had to endure the person in front of you putting his seat down from start to end?  Annoying like hell..  Well here’s the trick to combat that “Knee Defender”, you lower the table/tray in front of you and attach this Knee Defender and viola the seat in front of you is locked in it’s upright position –  but yes the tray/table has to be down for this to work, nothing is free so that is the drawback to this little trick.   At a price of US$ 15,- it’s a bargain for those transatlantic trips.
